Let’s get this straight, the engine is NOT LEAKING OIL. The fuel is a mixture of lubricating oil and a highly flammable component. In my day, the 1950s, we used castor oil for the lubricant and kerosene and ETHER for the flammable bit. In those days you could go to a Pharmacy, in England they were knows as just Chemists shops, and as long as you had a laboratory bottle with a ground glass stopper you could buy 8 ounces of ETHER. Some times the Chemist would ask what you wanted it for and you would say that it was for model airplane engine fuel, there was rarely a problem. The fuel was a mixture of equal parts Castor oil, Kerosene (Paraffin in England) and ETHER. The engine burned the Kerosene and the ETHER and the Castor oil was just splashed all over the internal moving parts of the engine. The Castor Oil was NOT consumed and was just blown out of the exhaust port and as others have said it ended up coating the front of the plane. I never had this kind of engine which was know as a Glow-plug engine, the battery was used to get the plug glowing until the engine started to run. Then the heat of the combustion kept the plug glowing without the battery, the fuel formula for these engines was slightly different from what I have described. My engines were DIESEL engines and did not require a glow plug, they did have a mechanism which enabled you do adjust the compression at the top of the piston stroke. This was always VERY TRICKY to get right and resulted in many banged up fingers as you had to adjust a screw at the top of the cylinder while the engine was running. Young fingers and propellers running at 8 to 10,000 RPM do not mix without PAIN. Good heavens all this happened almost 70 years ago, I can barely believe it. But it was GREAT FUN, my mother stayed in the house not wishing to see the carnage that she confidently expected to occur. Good job I never told her about the Gun Cotton that I used to make. I used to test the quality of the gun cotton by placing a small amount on the concrete floor of the workshop and hitting it with a hammer. SPECTACULAR RESULTS, until one day the gun cotton literally blew the head off the hammer which then crashed straight through the glass of the workshop window. I do not remember how I explained that one. Best wishes, stay safe and thanks for the memories, didn’t someone else say that?
Nitro Methane and castor oil I had the golden bee and the scar on my index finger to prove it. My father and grandfather were scared shi_less to go back home to his mother-in-law and his wife.
Oil is getting everywhere outside the engine so it is leaking The model works but its a terrible design to have oil just leak all over the place from the combustion chamber vent. it would be better if it didn't need oil in the fuel and self lubricated from a oil reservoir.
DarkShadowsX5 These are TOYS, not professional engines. These engines have been around since WWII, the6 are very cheap devices. When I first used these engines in the 1950s they cost less than the equivalent of about $10. WHAT DO YOU EXPECT.
@@darkshadowsx5949 Don't you get that these are Model engines? Yes there do exist cleaner running engines, ones that run on actual gas and 2 stroke oil, but they have to be much bigger to do so. Does this thing look big to you? I doubt it's bigger than my steam engine, seriously, this things is TIIIINY. Of course it would be better if it didn't need so much oil in the fuel. But we don't live in a perfect world do we? We have to make compromises. This one means smaller, lighter engine. Can't do that with a 4 stroke which would need valves, a cam shaft and many other additional things that add weight and size.
@@darkshadowsx5949 I do really wonder why you are not mentioning that in a model plane is no place for a person... normally the engine is used with some sort of an exhaust pipe so the oil will not mess up the motor. btw A leak is something where something is leaving a system, where it is not designed to. The exhaust is designed to let gas and oil out of the combustion chamber. So it is NOT a leak.
Watching this brought back a flood of memories. For a moment I imagined the exhaust smell coming from my cox .049 plane as I would tune the needle valve before running out to the control line to put it in the air.
Quadcopter 101 I used to myself fly the .049 Cox planes when I was a kid back in the 70’s. Now fly $2000 60cc gas airplanes and the Cox airplanes will always be my best memories.
As a kid, I played around with these engines all of the time. I really enjoyed tearing them down, and rebuilding them. I had control line airplanes (Cox, and balsa models with the Cox engines), a Cox 3-wheeled motorcycle, and even a flying saucer with one of these engines.
@@kestonramdeo8419 Diesel fuel. Cox engines ignite the fuel with glow rings. Just like diesel engines ignite fuel with glow plugs. There is no spark plugs, so no glow ring, no ignition. Don't waste your time if you don't have a glow ring in it, a 9 volt battery, and use diesel (or Cox engine fuel). It won't run without all of those. Understand that gasoline and diesel are different in that gasoline does not ignite when pressurized. Diesel fuel does. But it has to be brought up to a certain temperature before it does. That's where the glow plugs or ring comes in. Initially, they start the engine by glowing hot electrically and compressing (pressurizing)the fuel (spinning the prop) Once the engine is running, the glow plugs stays hot by itself and the engine runs. Unplug the battery from the glow ring. Ever see what happens when you hit a can of WD-40 with a sledgehammer? DONT DO IT. WD-40 is mostly diesel fuel. In the can, it's already compressed. Another sudden compression increases the temperature past a flashpoint and BOOM!! There's a video of it in TH-cam somewhere.
My hair, my clothes and body used to reek of the exhaust from these little engines. Just hearing this video, I can smell it again! The summers I remember most.
I'm 19 and always was fascinated by models and RC stuff. My jaw dropped when I saw that and made the instant decision to get one. Needless to say prices have gone crazy but I got mine, runs very well and the satisfaction of owning such a cute thing was worth it. So weird to read comments of people who grew up in the 50s... I felt nostalgic of an era I wish I was born in !
I still have two of them. A Peewee 0.020 and a Teedee 0.049. Have not run them for many years. Crashed many of the plastic ones and balsa control line models as a youth. Had a 0.049 Baby Bee with a tank extender on a 36" wingspan model and with a full fuel load it flew in a huge circle and out of sight almost. When it finally ran out of fuel I guestimated it was up 3000 feet and glided straight North East of us and never found it. Still have two scars on my finger to this date. Those days were great fun for us kids and still remember that last flight.
I remember building a small sled out of my Erector Set back in the 1950's. I put "outriggers" on each side. A thin layer of sheet metal gave the bottom surfaces a flat area. Then I took one of these Cox engines and mounted it on the back. (Think "swamp boat pusher"). I grew up on a farm so I had plenty of outdoor space available. After a snow, I would put this little contraption down on some hard-packed snow and it would go like the blazes. I had not considered the possibility that one of the outriggers might catch in the snow but that is what happened. That turned out not to be a bad thing, however. When one of them would snag on a little high-spot on the snow, it would immediatly spin my sled, sending it off in a new direction. Do much fun! Thanks for bringing back the memory! 😅 😂 🤣
Herr Unsinn, I did the same thing using the same size motor. I mounted it on a wooden cheese box (Yes at one time cheese came in a small wooden box). For skis, I used the standard white flat metal curtain rods. They worked great and as you described as the sled would hit a bump, it would instantly change direction. I used to get the great laughs just watching it go. Great memories.
We used these on small control line airplanes in the late 60's and early 70's. Lots of fun. The .049 size was the most popular small engine. Then we moved up to .35 .40 .60 ect. Had to wear leather gloves to start them. Nice childhood memory. Thanks
A 15 was a 2.5 cc. couldn't wear gloves, they tended to get caught up. When someone asks " doesn't that hurt? " you just hold up a hand with one finger down, 'hiding' it and say " you don't notice after the first one." I've got one .049 but never used it, had one earlier but it was stolen. I think I have somewhere a .01, a couple of 15's, a 30 or 35, a 40 and a 45 ( 7.5 cc ). I built a propeller driven car, started with a 15 with a manual throttle, a lever attached to the front of the deck working the throttle and a couple of springs on the front axle in case it hit a rock or something. you start it up and let go. it would drive around in circles until it ran out of fuel ( methanol and oil ) or it hit something. One day it was heading towards a parked car so I tried to grab it, hand hit the front axle which moved out of the way and thumb hit the top of the prop. Blood everywhere. rebuilt that car with the 45 but RC controls.
What great memories this brings back!! I just wish you could transmit smell to us! Shortly after I would get it running, I was cleaning mud and debris from the engine, never mastered string flight! Thanks for posting.
I purchased one of these .010 when it came out, still have it, mine is red. There is also the mount for external fuel tank. My father was ham radio operator and we built small radio control plane. It flew long time with that engine. Thanks for good video.
Mine was red, too. Well, the fuel tank was. PeeWee Thistle Drome model, or something like that. I spoke no word of English then, so I might misremember.
@@wafikiri_ Hi, Mine was red also, maybe from 1970-1972, The engine nickname was the TEE DEE .010. And the other word was Thimble Drome. Yeah, airdrome-aerodrome, a thimble is small so it is like a classing scale. If you notice in some of their ads and packages, you can see a plane flying out of a thimble. Fun times.
@@watcher818 Thimble Drome, thanks! I'm pretty sure my engine's model was Pee Wee. So they had a series of similar models. Interesting. Mine was .010 too. It took me two years to get it started. The instructions said to turn the throttle screw 2.5 turns outwards, and I tried many other settings. Finally I got it at 22 turns.
Back in 1975 I used to have a COX PT-19 Plane that had similar engine, 0.049 cu-in with a glow plug and same spring starter. The flying model had control line. Good old days 😌
Irfan I had one too. It was a blast to fly. I was the youngest of five boys but I was the first to do a succesful loop with a line controlled airplane in my family. Thank God we didn't have computers back then. Think of the fun we probably would have missed out on.
I too remember taking these engines apart many times as a lad. I was baffled then (and now) how the fuel air mixture being scavenged into the crankcase found its way to the combustion chamber without benefit of 2 stroke style transfer ports. Thank you for posting.
I remember these Cox engines as a kid. Even though I haven't had one in 45 years, just watching this I could smell the fuel and exhaust again!!! Cool video!
Exactly. Funny thing for me is, I thought these little buggers where still in production. Strange that our child hood toys have become TH-cam novelties. I remember cutting grass and delivering newspapers all summer in order to purchase a fly by string Cox powered Messerschmitt bf 109. Completely destroyed it on it's first flight. Oh well.
Bruce Johnston Took mine to school and started it in the classroom at lunch, to impress girls. Quickly found out, my teacher WAS NOT impressed at all...
Hello friend, I am 79 years old. Since I was 15 years old I am a model airplane practitioner in all its facets. I started with “circular flight” and currently I fly everything that flies; motor sailplanes, sailplanes without motor, glow motors, electric motors, glow and electric helicopters. With 65 years of modeling, I think I have nothing left to discover. When I turned 60 I took out the ULM pilot title and flew successively in Quick Silver, Tecnam P92 and Tecnam Sierra. The doctors forced me to fly with a security pilot due to cardiac issues and desperate, I left him selling my Tecnam Sierra. I only fly model airplanes and, by the way, with all the experience accumulated last September 13, a Sukhoi propeller cut two fingers at the root of my nails. I know very well the stories you tell me because I have lived them. Regards.
"the battery was used to get the plug glowing until the engine started to run. Then the heat of the combustion kept the plug glowing without the battery" ... a pessoa q teve essa ideia é um genio ...
thank you. would you be able to share some more infomation? -how does the chamber gain gas? an how push out burnt gas? -is it open chamber and gas keep pumped in after exhaust? and remaining gas at exposion be used for oil for moving parts? -is it 2 cycle ? up(intake-compress) down(explode-exhaust) Thank you Sir.
@@igobrave1076 The fuel is drawn up the cylinder wall past the piston-notice there's no piston ring. Exhaust gas exits out the obvious port. Fuel/air mix is controlled by the Venturi valve at the front of the engine. Very simple. On this engine the glow plug comes as part of the cylinder head.
Of course, these engines work, I have used them for 40 years! These were the first engines made using CNC Machining in mass production. Many model airplane hobbyists started with engines in this series. The most popular being the .049 displacement series. 0.010, 0.020, 0.049, 0.051, 0.090. 0.15 displacements were available. There may have been a 0.074 even. There were even Conversion Heads available
I had a .09 Tee Dee on a 2.5m (98") motorglider. And it was balsa and ply construction, covered in Monokote, not this foamie rubbish that people play with today.
It seems that the author of the video talking about his .010 engine as if it was a new and fantastic invention. He may have been born yesterday but like you, i also remember the TD line of these little engines as I had several of them including .051 and the .074 for my cl airplanes. I wish I still had them today. Reading all of these comments was like a walk through memory lane and nothing to do with the video.
These little Pee Wee engines were so easy to work on and started with just one spin of the prop. Adjusting the engine speed was a simple turn of the screw next to the fuel filler pipe. We also fitted them to flat bottom model boats and had great fun...
How wonderful! I had a Cox model of a P51 mustang with the .49, it needed EXTREMELY LONG guide lines. I carved a "line car" out of balsa wood and had to spin the .49 backwards to drive it. What fun! And just like that! POOF! Im 10 years old again.
Still I have the Cox 0.049 that I used 50 years ago with a little U-control plane I made witk balsa wood. The only thing that that plane had doing was flying in circles surrounding me. After few minutes , the fuel finished and the plane landing, fully dirty of oil. Today , no child is happy playing to that. Regards from Argentina.
Never a doubt in my mind, heck yeah they will work. Great vlog, thanks for sharing! Got one in my shop now, but, hasn’t been in a plane in over 10 years. Learned along time ago that easy does it on tightening stuff on a aluminum engine, whatever, easy does it on the torquing. That spring starter saved a bunch of fingers!
I just saw this for the first time I'm 57 years old and I have alot of these types of engines,cox,testors, wen Mac. I've got p40 Warhawk and a p51 mustang (testors) brand I was partial to them. I got cars and now I'm going to pull them out thanks to this video and maybe run them. Thanks for the motivation!
childhood memories!!! the planes, the cars and the always burnt out glowheads!!!! lol wouldnt trade a day of them tho!! Oh and the smell of castor oil....great video, can almost smell it running!! thank you for sharing.
Excellent video. I remember the Cox range of model motors in the 50's. They were brilliant for their cost and performance. I've still got a couple of Pee Wees and a Medallion 0.15 up in the attic somewhere. Must get them out.
I bought one of those right after they came out, early 80's as I recall. Sadly I got sick and was off work for about a year with no income, so I had to sell off all those things just to survive. I WISH I STILL HAD IT!
Memories of my old COX 0.049. I had a few of these in the early 80's. I had a COX R/C van with the 0.049 motor. You could steer the van via RC but no throttle control via RC. Those were really fun days with my big brother. 40 years later we are still running nitro on road RC cars with each other and now our grown sons are racing with us. Great memories, thanks for posting.
I had a few of these cox .049 aircraft and car engines when I was a kid. Very reliable, but fussy when starting, and idling, but would run all day with plenty of model engine fuel. Most of them didn't have a carburetor, but a Reed valve in the fuel tank with an adjustable pin for fine tuning. This is an improved model with a carburetor.
its not really a carb, just a needle valve in a venturi, but this model has a rotary valve instead of read valve. They are only fussy is you don't set them up correctly (right amount of prime fuel/compression/glow power), I had mine down to one flick of the prop to start. I also modded my black widow/golden bee's to go from 18,000 rpm to 25,000 rpm by increasing sub port induction, this was on 10% nitro..
my favorite babe bee (.049) mod from back in the day was to drill a hole in the plastic tank mount/plate and plumb the internal tank pickup to an external 5 Oz. nitro-meth tank. I never had to go after my air boat in the water again. You would get bored before running out of fuel.
@Dave Micolichek Not arguing with you. I remember contemplating if it needed a cool down period and if the attached tank helped keep it cooler for the duration of the run. I simply decided it was worth the risk so I didn't have to keep swimming through duck crap to go get the boat when it unexpectedly ran out of fuel. That was at least 25 years ago and I bet I could go soak it in solvent for a day or two to get rid of the nitro-meth cocoon it is currently in and it would fire up.
Surely the definition of a carburettor is it a device to mix the fuel and the air in the right proportions for combustion. That is exactly what the needle valve and venturi does on all these engines thus they are carburettors.
No one talked about it was the cox dune buggie, 0.49 with pull start. Spent more time getting to run then I did play drive it. The worm gear made it to slow for me. Thanks for the video brought back memorys.
The little .049 was a great engine used on model planes in the 50's & 60's. 👍👍👍 Glow plug ignition, then it ran like a diesel!!! Sure did get a lot of "whacked" fingers!! 🤕😨
I have 2 of these Cox 010 engines new in original boxes. One is red , never run, in a plastic case and the black one which is test run only in a cardboard box. I have other Cox engines and over 200 various rare diesel engines, some 'Mills' going back to the 1940s.The ether kerosine (parafin) and caster oil smells lovely. It reminds me of my control line days in the 1960s. More fun than a smart (dumb) phone.
Loved these little screamers. Used to fly them in the '60s free flight in Victoria. Had to start them with the spring, if you tried to start without it it could start in reverse!
Even got one in my garage right now. Used it on a glider. The standard 1/2a model airplane engine .049 c.i. The one I have is smaller, it’s an .020 cox brand. The engine I have was just to get the plane up. Love that small starter spring, sure saves a bunch of sore fingers. These small engines are great pieces of engineering. Love them. Great video, thanks for sharing! I’ll sub and high five!
At 5:05 love the simple glo plug powering. That was always the problem when I was a kid. Flat batteries. This vid shows me how far battery technology has come in 60 years (Oh dear, that long!!!?)
Oh yeah. I remember when we did this long ago. We used a "dry cell", which was an enormous (like 2 1/2 inches diameter by 8 inches high) 1.5V battery and the things didn't last that long.
@@soaringvulture That battery was probably a gas-lighter battery, with a big screw thread around the top. These gas-lighters used a glowing filament (rather like a glow plug) to ignite the gas on your cooker. It worked well with the old "town gas" that was made from coal and consisted mainly of hydrogen and carbon monoxide, but it would not ignite the natural gas (methane) that replaced town gas in the UK around 1970. This large 1.5v cell disappeared from the market after that. Other batteries used for starting glow engines were the AD4 and AD34, which had four and eight (respectively) cells each the size of a large torch cell, all connected in parallel. These batteries were intended for heating the valve filaments of pre-transistor portable radios, so they were also disappearing by the 1970s.
That small airplane motor has been around since 1955! It’s nothing new or spectacular. What he does here, my friend, Dale, and I used to do this on a weekly basis. And when anyone buys one, buy a half dozen(6) glow plugs, don’t ask! And we had sore fingers from starting it, we had no spring starter, great invention. And they make a great battery clip for starting, but this guy evidently likes hot fingers.
OMG !!! Is this a COX .010 ?? I had a .049 Golden Bee and a red .. .020 (revving to 20,000 2-stroke RPM!!) ...back in the late '60's They were great lil engines... Flew some TEEENY control-line planes with them ! Thanks for the memories!! (Jamaica) ... P.S. At times a small bit of "something" would stick the reed valve open ..and I'd have to pull it down and clean in the field !
Spent every penny I earned, begged or otherwise acquired on the Cox .049 engines. They were engineering marvels, really and dirt cheap, costing only about $5-7 bucks in the late 1950s. They ran like crazy (in both directions) and were virtually indestructible. Never used the starter springs; flipped 'em by hand like real men! Wonder if they still make them...
I put one of these on a $5,00 Styrofoam glider from walmart, tossed it around a bit without running, to set elevator & balance, fired it up, and off it went, up into the great blue yonder. found it in the cornfield 2 miles away... (was an 040)
There was a smaller one, I have one NIB. The 010 was the smallest used in their plastic commercial planes like the Lil'Stinker Bipe. My favorite in the Cox line. I just found my box of 1/2A engines and a box of new glow plugs. I use them on gliders to get the altitude. Fuel is Methonal Alcohol+Nitro Methane+ Castor Oil. There are different blends but I use 15% Nitro with 18% Oil in all my engines. As long as these engines aren't rusted, the crank, then they will usually clean up and run.
In the 60s I had the car, plane, and dragster. The dragster was cool: hammer a nail into the asphalt. Tied a string to it. Looped a string through two grommets, one in the front of the dragster, looped into the front grommet. Then stretched a string as long as you wanted (about 100 yards for me). Nailed a second nail into the asphalt. Stared the little Cox engine. Zoooooooooooooooooooooom it zipped abought 60 mph down the road, guided by the string to the end.
It's not the same today for the most part. Back then , castor oil was used for lubricant and that is what gave it its distinctive smell while burning. Now, synthetic oils are used and it does not have the same nostalgic smell. However, some premium fuels use a blend of castor and synthetic
i had a bunch of these cox engines for my airplanes when i was a kid, .049, .020 and .010 sizes. i can still smell the burning fuel now, they were alot of fun.
Nice. I'm old enough to have owned a handful of these little cox engines both glow and diesel. Most you can flick start without the spring and when you get a real feel you can make the 49 four stroke on a very rich mixture. Happy days.
I have a great little .010 i fly on an old timer design balsa wood and tissue paper covered free flyer. It has a little mechanical pinch fuel cut-off and a fuse activated elevator pop up link that brings it down after a 5 minute max on a 30 engine runtime limit. I've had to go after this plane with my car in good thermal conditions, but I have never lost it. Walked a lot of corn and soybean fields to retrieve it over the years. Good little video, brought back a lot of flying memories.
Correct fuel for this the Cox TD 010 glo engine is 30 % nitromethane, 30% degummed castor oil and 40% methanol. Same fuel for all Cox TD racing series engines. TD glow heads all rated at 1.5v but TD's can usually be started on 1.2v. First series TD 010's had gold anodised crankcases and red plastic moulded parts. Second series natural finish crankcase and black plastic parts. Very good idea to disconect the fuel tube from the tank's plastic outlet before storage as the chlorine released from the tube material over the decades will attack the acetal tank material. Common TD 010 and 020 problem.
aeroearth? Hi! I was poor, so I only ever ran mine on a maximum of 3% nitro [three percent was all I could afford], and that was when using an 049 on a pod to lift a big RC glider. For free-flight with an 020 I'd use regular straight fuel - all my little Cox glow engines ran happily on it for many years. Amazingly high quality little bits of engineering. A glow head lasted a full 11month season for me. (I'm based in England; there's usually one unflyably stormy month in a year - but it's as likely to be in summer as in the depths of winter...) I found that the engines needed very little maintenance if kept clean; I hated stiff neoprene fuel tubing, and switched to silicone at the first opportunity. I still have a couple of unopened spare glow heads left from 1978! I loved everything about my tiny engines but the noise... :-)
Oh how I wish someone would have brought up the rights to Cox and remanufactured these engines as they were without any changes . I remember my first plastic U Control airplane (14 yrs old). It was a Piper Cub. When I started that .049, heard the whine of that little engine, and smile that nitro I was hooked for life. I'm 77 and still a RC modeler. Back then if I would have known Cox was going out of business I would have brought a dozen 049's and remember that little jewel of energy the .010, yeah a dozen of those too! What a joy these little engines were.
Nice to meet you! You flew a U-control plane a long time ago. The cox engine is still sold on eBay. Anyway, I hope you take care of your health and have fun as an R.C. modeler.
@@iguy Thank you, hope in these perilous times you and yours are safe well and happy. Here's me a few years back. th-cam.com/video/NhRQWnsIjZQ/w-d-xo.html
Garry Brpwine I had a TESTORS ,049cc, but 9 out of 10, it always ran backwards, so was NEVER on a plane, but my others were English, DIESELS A MILLS 1.3cc, then an ED 2,46cc, , and an ED 3,46 cc Hurricane, it would have been 25 or so years later, when in USA, that had glow plugs, 4, FOX .35cc engines, but used 2 volt plugs, and 2.2 volt wet cell battery, all u control planes.
Cox made these for about three decades. I've had a number of them over the years. I have never heard of them being recalled. They made millions of them. Most popular size was .049 c.u., but they also made .020, .010, .074 and .090.. Can't recall all the sizes, but they made a lot of them. You used to be able to buy them in every hobby store.
i have a small collection of Cox engines. One of these mounts a modern throttle conversion and will be perfect for my small P40. Cox engines are small jewels.
I regret selling my collection of COX motors. I had that one, along with many of the famous 049, and a bunch of really rare motors including 2 small diesels. I used to slice and dice my fingers getting them started, but it was worth it.
Wikus Van De Merwe , I made a leather sleeve for my right hand index finger, most of my early engines were all ENGLISH ones Mills 1,3cc, then ED 2.46cc, and the ED 3.46 cc Hurricaine, , we used to mix our own fuel, Ether, castor oil, and kerosene., had to keep the ether out of the house., racing,,would need an RX, for Amyl nitrate, for more oomph.!
I do indeed :) I miss the old glow engines so much -- even the look -- that I think it would be really cool to make an electric equivalent in the same shape with the same run-time, or more. No RC control. Just a power switch for on.
The starter spring was a nice innovation. Using a plastic starter stick was mandatory on a bigger motor with the wooden props; those babies could take a finger off, or lacerate it almost as bad.
A glow plug, Cox .49,! I had many of these! I had 12 model " fly by string" airplanes. If the " strings" weren't long enough you had to spin around very quickly. You needed a lot of room to fly them. Wow, this brings back memories! That sound, my mother insisted that I didn't start them in our backyard. In later years I got throttleable 1 inch, air craft motors for radio controlled flight. I still have 2 of the .49s. The Cox "golden" .49s motors were especially prized.
I was thinking the same thing! Mine lasted a year before I retired it. It had a tendency to smack the ground at speed. My planes flew on control lines, connected to a control horn. Thanks for posting this video! It brings back some great memories! 👍😁👍
What you are seeing is the reflection of the glow plug element in the cylinder head. It is the high temperature of the heat of the filament that ignites the fuel. The engine does get hot but certainly not that hot!
One whiff of burnt cox fuel in the air with eyes closed, and a rush of 45 year old memories would stream by. Oh the hours spent working on them . . . . endless. . . . way more than the time spent of them actually running the course.

Let’s get this straight, the engine is NOT LEAKING OIL.
The fuel is a mixture of lubricating oil and a highly flammable component.
In my day, the 1950s, we used castor oil for the lubricant and kerosene and ETHER for the flammable bit.
In those days you could go to a Pharmacy, in England they were knows as just Chemists shops, and as long as you had a laboratory bottle with a ground glass stopper you could buy 8 ounces of ETHER.
Some times the Chemist would ask what you wanted it for and you would say that it was for model airplane engine fuel, there was rarely a problem.
The fuel was a mixture of equal parts Castor oil, Kerosene (Paraffin in England) and ETHER.
The engine burned the Kerosene and the ETHER and the Castor oil was just splashed all over the internal moving parts of the engine.
The Castor Oil was NOT consumed and was just blown out of the exhaust port and as others have said it ended up coating the front of the plane.
I never had this kind of engine which was know as a Glow-plug engine, the battery was used to get the plug glowing until the engine started to run.
Then the heat of the combustion kept the plug glowing without the battery, the fuel formula for these engines was slightly different from what I have described.
My engines were DIESEL engines and did not require a glow plug, they did have a mechanism which enabled you do adjust the compression at the top of the piston stroke.
This was always VERY TRICKY to get right and resulted in many banged up fingers as you had to adjust a screw at the top of the cylinder while the engine was running. Young fingers and propellers running at 8 to 10,000 RPM do not mix without PAIN.
Good heavens all this happened almost 70 years ago, I can barely believe it.
But it was GREAT FUN, my mother stayed in the house not wishing to see the carnage that she confidently expected to occur.
Good job I never told her about the Gun Cotton that I used to make.
I used to test the quality of the gun cotton by placing a small amount on the concrete floor of the workshop and hitting it with a hammer.
SPECTACULAR RESULTS, until one day the gun cotton literally blew the head off the hammer which then crashed straight through the glass of the workshop window.
I do not remember how I explained that one.
Best wishes, stay safe and thanks for the memories, didn’t someone else say that?
Nitro Methane and castor oil I had the golden bee and the scar on my index finger to prove it. My father and grandfather were scared shi_less to go back home to his mother-in-law and his wife.
Oil is getting everywhere outside the engine so it is leaking
The model works but its a terrible design to have oil just leak all over the place from the combustion chamber vent.
it would be better if it didn't need oil in the fuel and self lubricated from a oil reservoir.
DarkShadowsX5 These are TOYS, not professional engines.
These engines have been around since WWII, the6 are very cheap devices.
When I first used these engines in the 1950s they cost less than the equivalent of about $10.
WHAT DO YOU EXPECT.
@@darkshadowsx5949 Don't you get that these are Model engines? Yes there do exist cleaner running engines, ones that run on actual gas and 2 stroke oil, but they have to be much bigger to do so.
Does this thing look big to you? I doubt it's bigger than my steam engine, seriously, this things is TIIIINY.
Of course it would be better if it didn't need so much oil in the fuel. But we don't live in a perfect world do we?
We have to make compromises. This one means smaller, lighter engine. Can't do that with a 4 stroke which would need valves, a cam shaft and many other additional things that add weight and size.
@@darkshadowsx5949 I do really wonder why you are not mentioning that in a model plane is no place for a person...
normally the engine is used with some sort of an exhaust pipe so the oil will not mess up the motor.
btw A leak is something where something is leaving a system, where it is not designed to. The exhaust is designed to let gas and oil out of the combustion chamber. So it is NOT a leak.
Watching this brought back a flood of memories. For a moment I imagined the exhaust smell coming from my cox .049 plane as I would tune the needle valve before running out to the control line to put it in the air.
Quadcopter 101 I used to myself fly the .049 Cox planes when I was a kid back in the 70’s. Now fly $2000 60cc gas airplanes and the Cox airplanes will always be my best memories.
I had one cox .49 in 1962
"Watching this brought back a flood of memories." Yep...me too!
Cox
That smell brings you right back every time dont it
As a kid, I played around with these engines all of the time. I really enjoyed tearing them down, and rebuilding them. I had control line airplanes (Cox, and balsa models with the Cox engines), a Cox 3-wheeled motorcycle, and even a flying saucer with one of these engines.
Can i use lighter gas fir them
@@kestonramdeo8419
Diesel fuel. Cox engines ignite the fuel with glow rings. Just like diesel engines ignite fuel with glow plugs. There is no spark plugs, so no glow ring, no ignition.
Don't waste your time if you don't have a glow ring in it, a 9 volt battery, and use diesel (or Cox engine fuel). It won't run without all of those.
Understand that gasoline and diesel are different in that gasoline does not ignite when pressurized. Diesel fuel does. But it has to be brought up to a certain temperature before it does. That's where the glow plugs or ring comes in. Initially, they start the engine by glowing hot electrically and compressing (pressurizing)the fuel (spinning the prop) Once the engine is running, the glow plugs stays hot by itself and the engine runs. Unplug the battery from the glow ring.
Ever see what happens when you hit a can of WD-40 with a sledgehammer? DONT DO IT. WD-40 is mostly diesel fuel. In the can, it's already compressed. Another sudden compression increases the temperature past a flashpoint and BOOM!! There's a video of it in TH-cam somewhere.
My hair, my clothes and body used to reek of the exhaust from these little engines. Just hearing this video, I can smell it again! The summers I remember most.
I'm 19 and always was fascinated by models and RC stuff. My jaw dropped when I saw that and made the instant decision to get one. Needless to say prices have gone crazy but I got mine, runs very well and the satisfaction of owning such a cute thing was worth it. So weird to read comments of people who grew up in the 50s... I felt nostalgic of an era I wish I was born in !
Where do you buy them?
@@michellegarn5318eBay basically anywhere accually but they will cost over $100
So small you have to measure its output in ponies instead of horses
Horseflies, not ponies.
Damn, that is better.

i woulda said seahorses
LOL
I still have two of them. A Peewee 0.020 and a Teedee 0.049. Have not run them for many years. Crashed many of the plastic ones and balsa control line models as a youth. Had a 0.049 Baby Bee with a tank extender on a 36" wingspan model and with a full fuel load it flew in a huge circle and out of sight almost. When it finally ran out of fuel I guestimated it was up 3000 feet and glided straight North East of us and never found it. Still have two scars on my finger to this date. Those days were great fun for us kids and still remember that last flight.
I remember building a small sled out of my Erector Set back in the 1950's. I put "outriggers" on each side. A thin layer of sheet metal gave the bottom surfaces a flat area. Then I took one of these Cox engines and mounted it on the back. (Think "swamp boat pusher"). I grew up on a farm so I had plenty of outdoor space available. After a snow, I would put this little contraption down on some hard-packed snow and it would go like the blazes.
I had not considered the possibility that one of the outriggers might catch in the snow but that is what happened. That turned out not to be a bad thing, however. When one of them would snag on a little high-spot on the snow, it would immediatly spin my sled, sending it off in a new direction.
Do much fun! Thanks for bringing back the memory! 😅 😂 🤣
Herr Unsinn, I did the same thing using the same size motor. I mounted it on a wooden cheese box (Yes at one time cheese came in a small wooden box). For skis, I used the standard white flat metal curtain rods. They worked great and as you described as the sled would hit a bump, it would instantly change direction. I used to get the great laughs just watching it go. Great memories.
The cutest manliest toy I've ever seen
it is NOT a toy fool.it is an old model airplane/glider engine
ok, an engine for a toy airplane then?
whatever
it's not a toy, *fool*
kostas karonis it took me to some clapped website called fool.it 😂😂
We used these on small control line airplanes in the late 60's and early 70's. Lots of fun. The .049 size was the most popular small engine. Then we moved up to .35 .40 .60 ect. Had to wear leather gloves to start them. Nice childhood memory. Thanks
A 15 was a 2.5 cc. couldn't wear gloves, they tended to get caught up. When someone asks " doesn't that hurt? " you just hold up a hand with one finger down, 'hiding' it and say " you don't notice after the first one."
I've got one .049 but never used it, had one earlier but it was stolen. I think I have somewhere a .01, a couple of 15's, a 30 or 35, a 40 and a 45 ( 7.5 cc ).
I built a propeller driven car, started with a 15 with a manual throttle, a lever attached to the front of the deck working the throttle and a couple of springs on the front axle in case it hit a rock or something. you start it up and let go. it would drive around in circles until it ran out of fuel ( methanol and oil ) or it hit something. One day it was heading towards a parked car so I tried to grab it, hand hit the front axle which moved out of the way and thumb hit the top of the prop. Blood everywhere. rebuilt that car with the 45 but RC controls.
i used a chicken stick......
What great memories this brings back!! I just wish you could transmit smell to us! Shortly after I would get it running, I was cleaning mud and debris from the engine, never mastered string flight! Thanks for posting.
I purchased one of these .010 when it came out, still have it, mine is red. There is also the mount for external fuel tank. My father was ham radio operator and we built small radio control plane. It flew long time with that engine. Thanks for good video.
Mine was red, too. Well, the fuel tank was. PeeWee Thistle Drome model, or something like that. I spoke no word of English then, so I might misremember.
@@wafikiri_ Hi, Mine was red also, maybe from 1970-1972, The engine nickname was the TEE DEE .010. And the other word was Thimble Drome.
Yeah, airdrome-aerodrome, a thimble is small so it is like a classing scale. If you notice in some of their ads and packages, you can see a plane flying out of a thimble. Fun times.
@@watcher818 Thimble Drome, thanks! I'm pretty sure my engine's model was Pee Wee. So they had a series of similar models. Interesting. Mine was .010 too.
It took me two years to get it started. The instructions said to turn the throttle screw 2.5 turns outwards, and I tried many other settings. Finally I got it at 22 turns.
Took me back 50 years.
Finicky, oily, dirty...best smell ever!
mam1627 - There is nothing like the spell of nitro-methane in the morning.
@@rogertycholiz2218 Yes
Back in 1975 I used to have a COX PT-19 Plane that had similar engine, 0.049 cu-in with a glow plug and same spring starter. The flying model had control line. Good old days 😌
Irfan I had one too. It was a blast to fly. I was the youngest of five boys but I was the first to do a succesful loop with a line controlled airplane in my family. Thank God we didn't have computers back then. Think of the fun we probably would have missed out on.
I too remember taking these engines apart many times as a lad. I was baffled then (and now) how the fuel air mixture being scavenged into the crankcase found its way to the combustion chamber without benefit of 2 stroke style transfer ports. Thank you for posting.
Now I can drive my hotwheels around!
I had one of those on a U-controlled Stuka back in the 70s. Had a ton of fun with it.
Fly a model JU-87 today and it'd be a Hate Crime!
I remember these Cox engines as a kid. Even though I haven't had one in 45 years, just watching this I could smell the fuel and exhaust again!!! Cool video!
I LOVED the smell of that fuel and exhaust! Probably brain damaged as a result. :D
I've just remembered I had slot cars with the famous cox engine , like 50 years ago
Brings back memories
Exactly. Funny thing for me is, I thought these little buggers where still in production. Strange that our child hood toys have become TH-cam novelties. I remember cutting grass and delivering newspapers all summer in order to purchase a fly by string Cox powered Messerschmitt bf 109. Completely destroyed it on it's first flight. Oh well.

Took mine to school and started it in the classroom at lunch, to impress girls.
Quickly found out, my teacher WAS NOT impressed at all...
Hello friend, I am 79 years old. Since I was 15 years old I am a model airplane practitioner in all its facets. I started with “circular flight” and currently I fly everything that flies; motor sailplanes, sailplanes without motor, glow motors, electric
motors, glow and electric helicopters. With 65 years of modeling, I think I have nothing left to discover. When I turned 60 I took out the ULM pilot title and flew successively in Quick Silver, Tecnam P92 and Tecnam Sierra. The doctors forced me to fly with a security pilot due to cardiac issues and desperate, I left him selling my Tecnam Sierra. I only fly model airplanes and, by the way, with all the experience accumulated last September 13, a Sukhoi propeller cut two fingers at the root of my nails. I know very well the stories you tell me because I have lived them. Regards.
"the battery was used to get the plug glowing until the engine started to run.
Then the heat of the combustion kept the plug glowing without the battery" ... a pessoa q teve essa ideia é um genio ...

@@rabihghannoum4902 they're kinda expensive man
thank you.
would you be able to share some more infomation?
-how does the chamber gain gas?
an how push out burnt gas?
-is it open chamber and gas keep pumped in after exhaust?
and remaining gas at exposion be used for oil for moving parts?
-is it 2 cycle ?
up(intake-compress)
down(explode-exhaust)
Thank you Sir.
@@igobrave1076 The fuel is drawn up the cylinder wall past the piston-notice there's no piston ring. Exhaust gas exits out the obvious port. Fuel/air mix is controlled by the Venturi valve at the front of the engine. Very simple. On this engine the glow plug comes as part of the cylinder head.
@@virtualgod3324 - These Cox.020 engines are about $200.00USD if you can find one used. A new one a lot more.
Oh yeah the little Cox that could! It was the workhorse of my model airplanes, dune buggies, and VWs I had as a kid.
Of course, these engines work, I have used them for 40 years! These were the first engines made using CNC Machining in mass production. Many model airplane hobbyists started with engines in this series. The most popular being the .049 displacement series. 0.010, 0.020, 0.049, 0.051, 0.090. 0.15 displacements were available. There may have been a 0.074 even. There were even Conversion Heads available
k nerd
I had a .09 Tee Dee on a 2.5m (98") motorglider. And it was balsa and ply construction, covered in Monokote, not this foamie rubbish that people play with today.
It seems that the author of the video talking about his .010 engine as if it was a new and fantastic invention. He may have been born yesterday but like you, i also remember the TD line of these little engines as I had several of them including .051 and the .074 for my cl airplanes. I wish I still had them today. Reading all of these comments was like a walk through memory lane and nothing to do with the video.
I had an .074 but it was an OK Cub.
These little Pee Wee engines were so easy to work on and started with just one spin of the prop. Adjusting the engine speed was a simple turn of the screw next to the fuel filler pipe. We also fitted them to flat bottom model boats and had great fun...
How wonderful!
I had a Cox model of a
P51 mustang with the
.49, it needed EXTREMELY LONG guide lines.
I carved a "line car" out of balsa wood and had to spin the .49 backwards to drive it.
What fun! And just like that! POOF! Im 10 years old again.
Still I have the Cox 0.049 that I used 50 years ago with a little U-control plane I made witk balsa wood.
The only thing that that plane had doing was flying in circles surrounding me. After few minutes , the fuel finished and the plane landing, fully dirty of oil.
Today , no child is happy playing to that.
Regards from Argentina.
Still got mine from 1960
I had a Cox .049 and a .15. Great fun!
Never a doubt in my mind, heck yeah they will work. Great vlog, thanks for sharing! Got one in my shop now, but, hasn’t been in a plane in over 10 years. Learned along time ago that easy does it on tightening stuff on a aluminum engine, whatever, easy does it on the torquing. That spring starter saved a bunch of fingers!
I just saw this for the first time I'm 57 years old and I have alot of these types of engines,cox,testors, wen Mac. I've got p40 Warhawk and a p51 mustang (testors) brand I was partial to them. I got cars and now I'm going to pull them out thanks to this video and maybe run them. Thanks for the motivation!
childhood memories!!! the planes, the cars and the always burnt out glowheads!!!! lol wouldnt trade a day of them tho!! Oh and the smell of castor oil....great video, can almost smell it running!! thank you for sharing.
Excellent video. I remember the Cox range of model motors in the 50's. They were brilliant for their cost and performance. I've still got a couple of Pee Wees and a Medallion 0.15 up in the attic somewhere. Must get them out.
Still have mine from that era, and even the older ones from the 40's that used spark plugs.
Still have a "Sea Fury" outboard motor.
I learned to fly Ucontol on .049 size engines when i was 11-12yrs old. Great vid. Takes me back when kids had hobbies! This is very cool…
never had an 010 but brings back fond memories of the 049. those were the days!
I bought one of those right after they came out, early 80's as I recall. Sadly I got sick and was off work for about a year with no income, so I had to sell off all those things just to survive. I WISH I STILL HAD IT!
Yep that one is called a "Wanker" rotary motor :)

Gizawar when you have desire to correct or inform don't do it to those that don't need it, if you're unsure just assume they know unless they ask.
Gunzee no
Reminds me of my Frog 80, circa 1966. Only my little engine was diesel, (no glow plug) and it ran off an ether /oil mix fuel.
I still have an ED Racer diesel, 2.5cc, it's in a Keil Kraft RAF Crash Tender.
OMG I had couple of these on 70's COX 0.10 , 0.20 and 0.45 thanks for sharing
Puts a smile on my face. Cox 0.049 - great memories.
Memories of my old COX 0.049.
I had a few of these in the early 80's.
I had a COX R/C van with the 0.049 motor. You could steer the van via RC but no throttle control via RC.
Those were really fun days with my big brother. 40 years later we are still running nitro on road RC cars with each other and now our grown sons are racing with us.
Great memories, thanks for posting.
I had a few of these cox .049 aircraft and car engines when I was a kid. Very reliable, but fussy when starting, and idling, but would run all day with plenty of model engine fuel. Most of them didn't have a carburetor, but a Reed valve in the fuel tank with an adjustable pin for fine tuning. This is an improved model with a carburetor.
its not really a carb, just a needle valve in a venturi, but this model has a rotary valve instead of read valve. They are only fussy is you don't set them up correctly (right amount of prime fuel/compression/glow power), I had mine down to one flick of the prop to start. I also modded my black widow/golden bee's to go from 18,000 rpm to 25,000 rpm by increasing sub port induction, this was on 10% nitro..
my favorite babe bee (.049) mod from back in the day was to drill a hole in the plastic tank mount/plate and plumb the internal tank pickup to an external 5 Oz. nitro-meth tank. I never had to go after my air boat in the water again. You would get bored before running out of fuel.
@Dave MicolichekRan it for hours and hours that way. I liked it more than my queen bee.
@Dave Micolichek Not arguing with you. I remember contemplating if it needed a cool down period and if the attached tank helped keep it cooler for the duration of the run. I simply decided it was worth the risk so I didn't have to keep swimming through duck crap to go get the boat when it unexpectedly ran out of fuel. That was at least 25 years ago and I bet I could go soak it in solvent for a day or two to get rid of the nitro-meth cocoon it is currently in and it would fire up.
Surely the definition of a carburettor is it a device to mix the fuel and the air in the right proportions for combustion. That is exactly what the needle valve and venturi does on all these engines thus they are carburettors.
I have same one. I bought in 1998 with my Cox Line Control Plane. Good times.
Great video! Keep going!
No one talked about it was the cox dune buggie, 0.49 with pull start. Spent more time getting to run then I did play drive it. The worm gear made it to slow for me. Thanks for the video brought back memorys.
The little .049 was a great engine used on model planes in the 50's & 60's. 👍👍👍 Glow plug ignition, then it ran like a diesel!!! Sure did get a lot of "whacked" fingers!! 🤕😨
This one is acually an 010 not 049
Ill second that
Had one of these in a Cox PT19 flight trainer fbw decades ago :)
Amazing little engine. I had a Cox Pitts Special control line biplane that I flew in my basement and outdoors many decases ago.
I had remote controlled cox cars with that kid of motor in the 70s. The were powerful and loud. I loved them👍
Worked all summer in the strawberry fields to pay for my model with a cox .020. Got a whole half lap in the tennis court before the crash.

I have 2 of these Cox 010 engines new in original boxes. One is red , never run, in a plastic case and the black one which is test run only in a cardboard box. I have other Cox engines and over 200 various rare diesel engines, some 'Mills' going back to the 1940s.The ether kerosine (parafin) and caster oil smells lovely.

Excellent video, very well done too. Thank you : )
Thank for what?
Even got one in my garage right now. Used it on a glider. The standard 1/2a model airplane engine .049 c.i. The one I have is smaller, it’s an
.020 cox brand. The engine I have was just to get the plane up. Love that small starter spring, sure saves a bunch of sore fingers. These small engines are great pieces of engineering. Love them. Great video, thanks for sharing! I’ll sub and high five!
I was playing with it 25 years ago, and it's coming out here now.
At 5:05 love the simple glo plug powering. That was always the problem when I was a kid. Flat batteries. This vid shows me how far battery technology has come in 60 years (Oh dear, that long!!!?)
Oh yeah. I remember when we did this long ago. We used a "dry cell", which was an enormous (like 2 1/2 inches diameter by 8 inches high) 1.5V battery and the things didn't last that long.
@@soaringvulture That battery was probably a gas-lighter battery, with a big screw thread around the top. These gas-lighters used a glowing filament (rather like a glow plug) to ignite the gas on your cooker. It worked well with the old "town gas" that was made from coal and consisted mainly of hydrogen and carbon monoxide, but it would not ignite the natural gas (methane) that replaced town gas in the UK around 1970. This large 1.5v cell disappeared from the market after that. Other batteries used for starting glow engines were the AD4 and AD34, which had four and eight (respectively) cells each the size of a large torch cell, all connected in parallel. These batteries were intended for heating the valve filaments of pre-transistor portable radios, so they were also disappearing by the 1970s.
That small airplane motor has been around since 1955! It’s nothing new or spectacular. What he does here, my friend, Dale, and I used to do this on a weekly basis. And when anyone buys one, buy a half dozen(6) glow plugs, don’t ask! And we had sore fingers from starting it, we had no spring starter, great invention. And they make a great battery clip for starting, but this guy evidently likes hot fingers.
Seems like nobody except us old farts ever heard of Cox engines before
OMG !!! Is this a COX .010 ?? I had a .049 Golden Bee and a red .. .020 (revving to 20,000 2-stroke RPM!!) ...back in the late '60's They were great lil engines... Flew some TEEENY control-line planes with them ! Thanks for the memories!! (Jamaica) ... P.S. At times a small bit of "something" would stick the reed valve open ..and I'd have to pull it down and clean in the field !
Spent every penny I earned, begged or otherwise acquired on the Cox .049 engines. They were engineering marvels, really and dirt cheap, costing only about $5-7 bucks in the late 1950s. They ran like crazy (in both directions) and were virtually indestructible. Never used the starter springs; flipped 'em by hand like real men! Wonder if they still make them...
I put one of these on a $5,00 Styrofoam glider from walmart, tossed it around a bit without running, to set elevator & balance, fired it up, and off it went, up into the great blue yonder.
found it in the cornfield 2 miles away... (was an 040)
HA! Great minds think alike.. ツ

Mark Arnott which?
WOOOOOW!!! AWESOME!!!!
There was a smaller one, I have one NIB. The 010 was the smallest used in their plastic commercial planes like the Lil'Stinker Bipe. My favorite in the Cox line.
I just found my box of 1/2A engines and a box of new glow plugs.
I use them on gliders to get the altitude.
Fuel is Methonal Alcohol+Nitro Methane+ Castor Oil. There are different blends but I use 15% Nitro with 18% Oil in all my engines.
As long as these engines aren't rusted, the crank, then they will usually clean up and run.
In the 60s I had the car, plane, and dragster. The dragster was cool: hammer a nail into the asphalt. Tied a string to it. Looped a string through two grommets, one in the front of the dragster, looped into the front grommet. Then stretched a string as long as you wanted (about 100 yards for me). Nailed a second nail into the asphalt. Stared the little Cox engine. Zoooooooooooooooooooooom it zipped abought 60 mph down the road, guided by the string to the end.
Still have my cox Chaparral, Prop Rod and Jeep.
I can still smell the fuel we used back in the early '70s!
It was diffrent beacouse it had lead right??
I still have a can of cox fuel!
It's not the same today for the most part.
Back then , castor oil was used for lubricant and that is what gave it its distinctive smell while burning.
Now, synthetic oils are used and it does not have the same nostalgic smell.
However, some premium fuels use a blend of castor and synthetic
That was my first thought too.The smell of the seventies.
LiPo batteries don`t smell (and they don`t smear your model in a thick film of castor oil).
i had a bunch of these cox engines for my airplanes when i was a kid, .049, .020 and .010 sizes. i can still smell the burning fuel now, they were alot of fun.
Nice. I'm old enough to have owned a handful of these little cox engines both glow and diesel. Most you can flick start without the spring and when you get a real feel you can make the 49 four stroke on a very rich mixture. Happy days.
I had a .75cc diesel when I was a kid. I took it into the cinema and ran it for about ten seconds during a film. I never got caught.
Until now...
Who did you ran it in cinema??
Top 10 criminals who never got caught
awesome little engine

I still have one of those somewhere, fantastic little engines.
I have a great little .010 i fly on an old timer design balsa wood and tissue paper covered free flyer. It has a little mechanical pinch fuel cut-off and a fuse activated elevator pop up link that brings it down after a 5 minute max on a 30 engine runtime limit. I've had to go after this plane with my car in good thermal conditions, but I have never lost it. Walked a lot of corn and soybean fields to retrieve it over the years. Good little video, brought back a lot of flying memories.
Switch music off when engine runs.
Switch music off in general more like it.
Does anyone know the name of the music in this video. Thanks.
@@michaeldevito5575 Must be 'Cox Tee Dee' music coming out the exhaust ports of this Cox .010 unit.
Correct fuel for this the Cox TD 010 glo engine is 30 % nitromethane, 30% degummed castor oil and 40% methanol. Same fuel for all Cox TD racing series engines. TD glow heads all rated at 1.5v but TD's can usually be started on 1.2v.
First series TD 010's had gold anodised crankcases and red plastic moulded parts. Second series natural finish crankcase and black plastic parts. Very good idea to disconect the fuel tube from the tank's plastic outlet before storage as the chlorine released from the tube material over the decades will attack the acetal tank material. Common TD 010 and 020 problem.
30 percent nitro, jesus... my .6 ci thundertigre only use 10 %.. these lil buggers must run hot as hell
aeroearth? Hi! I was poor, so I only ever ran mine on a maximum of 3% nitro [three percent was all I could afford], and that was when using an 049 on a pod to lift a big RC glider. For free-flight with an 020 I'd use regular straight fuel - all my little Cox glow engines ran happily on it for many years. Amazingly high quality little bits of engineering. A glow head lasted a full 11month season for me. (I'm based in England; there's usually one unflyably stormy month in a year - but it's as likely to be in summer as in the depths of winter...) I found that the engines needed very little maintenance if kept clean; I hated stiff neoprene fuel tubing, and switched to silicone at the first opportunity. I still have a couple of unopened spare glow heads left from 1978! I loved everything about my tiny engines but the noise... :-)
Oh how I wish someone would have brought up the rights to Cox and remanufactured these engines as they were without any changes . I remember my first plastic U Control airplane (14 yrs old). It was a Piper Cub. When I started that .049, heard the whine of that little engine, and smile that nitro I was hooked for life. I'm 77 and still a RC modeler. Back then if I would have known Cox was going out of business I would have brought a dozen 049's and remember that little jewel of energy the .010, yeah a dozen of those too! What a joy these little engines were.
Nice to meet you!
You flew a U-control plane a long time ago.
The cox engine is still sold on eBay.
Anyway, I hope you take care of your health and have fun as an R.C. modeler.
@@iguy Thank you, hope in these perilous times you and yours are safe well and happy. Here's me a few years back.

Thank you for the video!
The engine sounds good.
The plane looks about 25 classes, Airfoil is Clark Y.
I miss those days.
Amazing, good job. That's crazy small!
Every boy had one in the 40's -- 50's .010 - .020 - .049 - .074
Brings back the memories. K&B .35.
You must have lived in a rich neighborhood because the average kid did not have these even if they wanted one until roughly '70's.
Read. My uncle bought me one. We were too poor to buy one. But kids have a knack for getting stuff.
I WISH I HAD ONE OF THOSE
Garry Brpwine I had a TESTORS ,049cc, but 9 out of 10, it always ran backwards, so was NEVER on a plane, but my others were English, DIESELS
A MILLS 1.3cc, then an ED 2,46cc, , and an ED 3,46 cc Hurricane, it would have been 25 or so years later, when in USA, that had glow plugs, 4, FOX .35cc engines, but used 2 volt plugs, and 2.2 volt wet cell battery, all u control planes.
Someone needs to make these and sell them as diy kits that would be awesome
i got these engines for 8 bucks a pop a while back.
They did in the 80s but were recalled
Cox made these for about three decades. I've had a number of them over the years. I have never heard of them being recalled. They made millions of them. Most popular size was .049 c.u., but they also made .020, .010, .074 and .090.. Can't recall all the sizes, but they made a lot of them. You used to be able to buy them in every hobby store.
You can still buy them, got one myself. The brand is COX, and they are mini-rc plane engines.
+roycehellion where? I'd love one of these
i have a small collection of Cox engines. One of these mounts a modern throttle conversion and will be perfect for my small P40. Cox engines are small jewels.
They have been around since I was a kid---years and years ago...neat little machines!
rogergcam - The Cox.010 & .020 & .049 were little beauties and a marvel in engineering. They were miniature internal-combustion engines.
I'm built a plane called Tweety Bird that ran on the Cox td-10 screaming at 27000 RPM LOL
I regret selling my collection of COX motors. I had that one, along with many of the famous 049, and a bunch of really rare motors including 2 small diesels. I used to slice and dice my fingers getting them started, but it was worth it.
Wikus Van De Merwe , I made a leather sleeve for my right hand index finger, most of my early engines were all ENGLISH ones
Mills 1,3cc, then ED 2.46cc, and the ED 3.46 cc Hurricaine, , we used to mix our own fuel, Ether, castor oil, and kerosene., had to keep the ether out of the house., racing,,would need an RX, for Amyl nitrate, for more oomph.!
Wikus Van De Merwe remember the golden bee. Known to always start.it was 049.
I do indeed :) I miss the old glow engines so much -- even the look -- that I think it would be really cool to make an electric equivalent in the same shape with the same run-time, or more. No RC control. Just a power switch for on.
Heck yeah ain't nothing like a cox 49 line control balsa airplane, man this brings back memories, hey? Do they still sell these?
The starter spring was a nice innovation. Using a plastic starter stick was mandatory on a bigger motor with the wooden props; those babies could take a finger off, or lacerate it almost as bad.
I can't remember seeing this particular engine as a kid but I can remember the PeeWee .020 engine. Some great memories. Thank you for that.
Finally found a motor to replace the rubber band in my balsa wood glider from the 5 @ 10 !!!!!! Totally Awesome !!!! Great Job !!!!!!
I have one of these engines Cox 0.20 hold it in my hand an run it. Also have the the Cox 0.049 as the one in the video. My engines are 55 years old.
Nise work sir
I used to play a lot with these when I was a kid 50 years ago. They were sold under the brand COX and you had several size of them....
Of course it will work, you're the imaginative guy!
Now turbo it.
It is already supercharged. By design, it is a crank-case supercharged two-stroke.
Just pump pure cocaine into it.
Can't turbo a 2 stroke unless it has valves....right?
SethIsDead hi
Hi
Very nice
So simple and very less parts and it steel runs
i had an engine like that once , came off of a plane on a string , pretty cool old stuff
A glow plug, Cox .49,! I had many of these!
I had 12 model " fly by string" airplanes.
If the " strings" weren't long enough you had to spin around very quickly.
You needed a lot of room to fly them.
Wow, this brings back memories!
That sound, my mother insisted that I didn't start them in our backyard.
In later years I got throttleable 1 inch, air craft motors for radio controlled flight.
I still have 2 of the .49s.
The Cox "golden" .49s motors were especially prized.
.049
@@SLJ2137694 This one is 5X smaller, it's a 0.010.
It was designed to work! I had 0.010 and 0.049 Cox for my U line planes.
me too
Looks like the old "Busy Bee" glow plug motor that I once had.
I was thinking the same thing! Mine lasted a year before I retired it. It had a tendency to smack the ground at speed. My planes flew on control lines, connected to a control horn. Thanks for posting this video! It brings back some great memories! 👍😁👍
Yup, .049 busy bee
Yup lil Cox with auto start
@@daviddou1408 You may be right. I thought it was the busy bee in NZ, but I'm going back 60 years and the old memory isn't as sharp as it once was.
Winding back just 1/2 turn is enough for starting , to prevent damage to the string also let the engine do the combustion.
Thanks again for sharing
Who remembers getting your fingers bit from the prop adjusting the needle valve? this took me back to when I was A kid in the 70's
The cute part is thay it's getting hot and you can see the metal turning red
i think thats the combustion happening in that transparent cylinder
What you are seeing is the reflection of the glow plug element in the cylinder head. It is the high temperature of the heat of the filament that ignites the fuel. The engine does get hot but certainly not that hot!
Bonitinho tudo que é pequeno é da hora eu gostei da música e do motorzinho também kk
Só vaza gasolina pra caralho né inviável como protótipo...tem q ser desperdício zero
One whiff of burnt cox fuel in the air with eyes closed, and a rush of 45 year old memories would stream by. Oh the hours spent working on them . . . . endless. . . . way more than the time spent of them actually running the course.
Fantastic !! COX .010
I feel like the man is a giant and the parts are normal sized
Caleb underrated comment!
