- Nitro engines used to be the only source of power for RC planes and helicopters -- in the days before electric motors became as powerful as they are now. This video offers newcomers to the hobby, a raft of information about nitro engines, how they work and what to consider if you're thinking of powering an RC plane with one.

Glad to see people still preaching the fun that is nitro. Nitro has always been the top dog in rc for me, the most fun. Great video!
Nothing can replace the thrill and adrenaline of nitro airplane it's an experience that you can feel only when you fly it.
Sir your videos are as always phenomenal ☺️
Nothing like the smell of Glow Fuel in the morning!! Great throwback!
Yes you’re correct, glow fuel, NOT nitro!!!
I primarily fly glow and routinely rebuild both 2 and 4-stroke engines. I know these things very well and still learned a ton from this video- you’re an amazing teacher and a wealth of information. Thank you for sharing!
" I LOVE THE SMELL OF METHANOL IN THE MORNING."
Not many people understood that.
@@TheZach78 I did :)
@@TheZach78 isn’t it a reference to a movie where he says I love the smell of napalm in the morning? Idk I’m too young lmao. My dad has a shirt that says I love the smell of two strokes in the morning
@@johncarlberg4481 true. Movie name appoclypse
Electric RC guy here, I'd love to see how these get installed on a model. So yes, please make the build video.
While your waiting, look for some other TH-cam videos, and try and see if there is someone in a rc plane club near you that can help you figure all the stuff out
If you have no clue, look at a manual for a old arf nitro plane, and that will give you a fairly good idea on how to do everything
blast from the past, I remember having to save up for my Saito, but the sound always made me smile. Still mounted on a walnut stand on my desk
I try to learn something new everyday, and after more than 35 years of playing with every type of radio control vehicle you still helped me achieve that goal for today! I already knew most of the information that you spoke of in your video, but all of that knowledge that I have came from years of experience that were either frustrating, expensive, or both. I would have given anything to have this information available to me all those years ago. Keep up the good work.
I've always been intrigued by miniature engines, that was a very interesting & enlightening video, thankyou.
Most important maintenance of a nitro engine is the after run of a nitro engine. The methanol corrodes the alloy but the Nitro attacks the alloy, when this happens the nitro "Pitts" the alloy leaving tiny pin sharp shards. These shards break off under combustion and score the sleeve, and also, finds its way into the bearings or bushings whatever the case me be. After a days running I unplug the models fuel line from the carburetor. I have a seperate fuel tank with 100% methanol, and I run the 100% methanol for about a minute to burn out the nitro from the engine. One thing to know is when switching from nitro of any content to 100% methanol, the engine will run lean for a 20 to 30 seconds than fall off high idle when all the nitro is burned out of the engine and then run at a more respectable idle. I use my finger much like a throttle exhaust to limit the rpm by placing my finger over the tuned pipes stinger and blip the pipe to keep the rpm's down until the nitro is completely burnt out of the engine. After the nitro burn out I use Marvels Mystery Oil as a after run lube. Ten years on an engine and the internals are like brand new with no ugly darkening. It is what it is.
When I first started flying in the 80's one off the more experienced guys turned up with a big pattern ship which had a pipe on it. I have to say that when he screwed the main in and it came on the pipe I legged it to a very safe distance. It was absolutely terrifying and exciting all in one go.
thanks for the info. I just bought a 2.43cc nitro engine for the time being.
'Definitely you were a school teacher. Wonderful teaching gift you posess.. I learned so much from this and just at the right time too! Just fascinated by these engines, and know I will retain it. Thanks 🇺🇸
Jeez after you mentioned tuned pipes, I started searching and I saw Dub Jett being mentioned in some forums, I had no idea they even existed never the less made very cool engines and still sell them! With less and less glow engine options in the market, this is amazing!
Your personality and way of speaking made this video 2x more fun to watch
A very exceptional job of catering to us Flyers who love model aircraft engines and the smell of the castor oil and methanol
Electric will never be the complete experience, ever. Nitro is the real deal in terms of experience in the RC hobby realm.
Old school or not. Over Half of my new builds either ARF or kit are built with Glow engines!
Nothing beats the sound. Smell. And sight of a plane spewing smoke while taking off!
I'd really like to.see you take on tuning a nitro motor maybe even do a blind tune or 2 so show us how to find that sweet spot from anywhere on the carb needles...
🍻cheers🥃
I second that!
have you ever tried to adjust a nitro engine? it needs to be hot and running to test,
if its spluttering it has too much fuel,
if it sounds like echo and runs very hot, it lean.
if its seized up, it was lean.
if the rpm is climbing high out of control, iiiiiii pobre ti
@@bartsshorts Never, I always ran methanol engines - fuel is way cheaper than nitromethane!
Ahhh.... The smell and sound!!!
Thanks for the video!!! U got me down memory lane.
Very informative and helpful, great video.
Excellent informative video
Nostalgia, use to play with these all the time.
Awesome, I havnt flown glow motors for a long time now, and Im happy I also learned a thing or two as well. Yeah Im keen on seeing a build, and also while you are at it do a tuning vid, will help a few out I think. This is a great tangent to explore. Thanks Bruce.
Happened to stumble upon this video as i acquired some nitro/glow engines. Super informative ... Learned some new things. And I recognize the voice from your other channel Bruce. Didnt realize this was your channel too... How cool!
Again, thanks for the education! Super helpful!
Excellent video!!! Thanks:)
You know I still have my 4 stroke motors. This next summer going to have them flying again. Miss that kind of flying
just watching the video makes me smell the old castor oil, I think I been around RC nitro motors a little too often lol
Started with Nitro and i can't stand electrics, to easy. I love to tinker and tune. Only real downfall is fuel costs and noise complaints.
for the complainers i always have my middle finger at the ready.
I never get noise complaints! Whenever I run them at my house all my neighbors think they're pretty cool and usually wander their way over to watch lol. Then again they're all gearheads. But still when I run them at parks or public places I've never gotten noise complaints. I think only a retard would complain about noise from a nitro
Recommend 4 stroke engines for lower noise output
@@t6vim12 4 strokes are no quieter than a 2 stroke. It's just the pitch of the sound. 2 Strokes are higher pitched
Dont you have to clean nitro engiens? no cleaning with electric
Thanks for the video! Very good timing as I just bought a Traxxas 4-tec as my first nitro anything.
Thank you Bruce very good video and yes a build video would be great.
I am new to the hobby. I have had a couple electric cars. Never really cared for them. But the nitros are epic. Just feels more realistic...
Great video Bruce! I took up the hobby around 5 years ago using electric planes, and decided to try nitro last year. I love it! I wish I had seen your video then, it would have answered a lot of my questions. This is the only explanation I have seen regarding glow plug ignition timing, which had me scratching my head until today. Please do the nitro plane build video!
Those were the good ole days! I'm still using them but mostly use electric conversions now for the simplicity of it!
Yes, would very much love to see a nitro build. You probably forgotten more than many of us know about nitro. 😀 I have picked up a few old airframes that will not easily convert to electric so nitro is in my future.
I've found so many cool things about nitro engines recently (and learnt a lot a bout combustion on the side) that It really makes me want to build an old-school trainer, use all the cool radios and servos we have now and fly high alpha like I used to do with my dad's planes. But now that you mention tuned pipes man that opens a whole new world of cool ideas I didn't know how much power they could add.
Also there is quite a few smaller gas engines now, and I'm sure with some fuel additives they can get to close to the power to weight ratios of glow engines, without the mess.
Enya #3, OS F and OS #8 best plugs ever. Bean oil is still the best and people still add a bit to modern synthetic fuels. I always used Morgan Omega at ~$10 US/gal w/10-40% nitro.
Thanks for the great video!! I'm new to the hobby (and had only an electric trainer), and have just won an older, beautiful and well built, plane in a raffle. It has a Webra Blackhead 10 ccm engine. Being new to glow/nitro (and the hobby in general) I really appreciate all the info!! I'm excited to go though it, give it some love, and hopefully get the plane in the air very soon! Thanks again!! 👍
Excellent Glow Engine info. Had many, many Glow engines before I went to Electric.
A lot of Glow engine info I was not even aware of. Thanks for enlightening me... ;-)
I’ve flown glow for probably 25 years but I still enjoyed this video and I’d like to see more glow back in the hobby. Electric started out as a novelty and now is mainstream and glow is the novelty. But I believe it will come back as a more mainstream power source. Especially if the fuel cost would come back under $20 a gallon
Yes I,m new to this and loving it. as I,m looking at a gas motor and looking at an old SEAGULL SEA275 JUNKERS CL1 G-BUYU love the look
great video!
Really good video, and a very detailed explanation.
I’m trying to get my son into the hobby, so I’m building a test bench for him.
And as far as I’m concerned, if it doesn’t make a noise, then it’s a powered glider. 🤭
Wot ho Bruce, Just watched four years late, my ASP 52 ABC motor has quite a large muffler, inside of this there is a multi holed baffle, not only dose the make this engine very quite, it’s fuel efficient because of the pulse made inside of this muffler helping to push the unburnt fuel from exiting or some such waffle. Way back in 62 my first motorbike was a 125 BSA Bantam, the carb had a strangler which was also had a choke leaver that cut off the air, inside this strangler was some wire wool this caught the fuel which was blown back by the engine, the wire wool caught this fuel and was reused.. it was a gutless thing. Still Ride motorbikes and on the odd occasion let other fly my plane I’ve build, over the years I had a few goes at flying RC not good I leave this to others with more skill. I prefer making free flight. Nice to see your still flying, although I did enjoy when you made the models..
Awsome video. Im jumping to nitro!!! How do I use tuned pipes?Could you plaese do a tutorial? Love your videos. I learned alot with you
Excellent video Bruce, very informative. :)
Cool a build... can't wait....
The nitro engine won't need recharging the model receiver/servo controller will still need a charge as will the control transmitter.
Fascinating info. Love the smell of Castor oil the same as Castrol M.
Do a build video. Also a tuning guide for glow would be great
you're the enceclopedia for RC. thanks for sharing your knowledge!
Very very nice and informative presentation.
Having grown up on nitro motors in the hobby, nice to see it addressed! Thanks. I'd like to see someone make a nitro quadcopter - that would be impressive.
You'd need a fast cvt for a quadcopter.
Great video my friend. I do a loooooot of nitro. And your right , it’s a hobby in itself. Great topic. Value your thoughts on the topic
IC reciprocating engine propeller propulsion is my favorite!
Awesome video and yes please to a nitro build video !
Bruce - i really enjoyed your informative and enthusiastic perspective / description of 'Glows / Nitro's'. As you commented, I am really enjoying discovering the challenges and drama of flying a glow; relieving my youth with model boats!. PLEASE do a build with a glow. I would love to learn more - and as others have commented, would like to learn more on tuning. I am getting there - but it would be good to hear from a pro. Thanks. Keep up the great work!
Thanks for making this video, I'd like to see a build video 👍💪
I've flown for over 20 years and then was out of the hobby for 15 what I've started seeing since coming back is it used to be when everyone flew glow or gas you could get a kind of sense where the other guy in the air is from the noise of his engine, but when I fly with my glow and someone has an electric I have no idea where they are until almost I'm right next to them when they are in sight of my plane. As a matter of fact at my air field I have seen 2 accidents where a Glo plane has cut an electric foamy in half because the glow plane was doing a flyby down the runway and the electric was doing some 3d stuff. I honestly think if the electric made noise or if it was an internal combustion engine that the glow guy would have had a sense where the other plane was and would have missed him.
ahh, the joy of a simple sig 4 star 40 and a saito 50. gonna do it for the summer. the most perfect combination of airframe/motor and fun i have ever had
An interesting introduction of glow plug engines. A little test run to hear the difference between 2 and 4 stoke would be nice. AND perhaps a brief mention of Diesel engines too. When I was younger about 75% of us started the hobby with 2,5 ccm diesels.
Still using castor in all my four strokes. Never had any bearing corrosion.
I agree synthetic oil is BS thats for sure, nothing but black goo. Anyways, how about "Propylene oxide" instead of methanol for the ignitor? illegal in IMPBA sanctioned racing. :) I don't use it! hahaha yeah I do.
Gregory Blake where i live its fine. No problems
I stopped flying competition F3a aerobatics about 20 years ago, but I used a combination of synthetic and Castor like Model Techs Duraglow or Superglow for my OS Prettner engines and Super Tigres. I don’t think much has changed.
Peter Hermit oh yeah i remember seeing those OS hanno .60s they were long stroke engines if i remember. Pretty cool.
Great vid pops!....I love nitro...so tired of fpv and quads.
Awesome video thanks
Thought for a moment I was on Joshua's channel ... because I learned something to day. Grew up with these motors, but never knew about the timing adjustment with the glow plug choice. But then not much choice in glow plug was available in those days in my neck of the world.
Change in nitro % also changes timing so better to use recommended nitro content as too mutch might damage your engine
Thanks, Bruce. Always preferred ic, more soul than 'lectric..
Hi Bruce, I have never flown nitro but I am very interested. But I can't understand how pressurising the fuel tank with hot exhaust is safe.. I know that it is, since its been done for decades, but is there some sort of valve or spark arrestor or other involved? Thanks for all your great videos 😊
Søren Svenne its ok with glow fuel. Dont ever do it with petrol.
I was hoping you would show how to tune a 2-stroke
Great video Bruce! I just got back into nitro as I purchased a Toyan 4 stroke overhead cam engine and installed it into a RC car. I am having a blast getting back into Nitro.
If you are interested I have done several videos about it.
I have worked on car engines for over 30 years. Always wanted to know how the rc nitro engines work. Thanks for such a complete video.
Here in the states nitro is still hanging on in the helicopter world, it is reduced but still present, some say that it is even starting to make a come back.
OS used to have problems with the cylinder liner.My old OS46. FX in a Sig cougar with a tuned pipe and the cylinder liner would eroude down to the copper .
Brilliant video and well produced and everything explained in a simplified way. Im flying model aeroplanes since May 1986. My first plane was an MFA YAMAMOTO with an OS 40 two stroke. The vast majority of my planes are glow planes both two stroke and four stroke. I do have a few electric planes and I enjoy them too everybit as much. But I still love to hear my fourstrokes and I still love to see a smoke trail across the sky for realism. Enjoyed this video very much. Thanks for sharing.
Excellent information, diversity of the conversation, enjoyable.
Very informative film had one gifted to me when I was wee 40 years ago had no idea how it worked had a wing bolt thing in where you have the glow plug on yoursIt must have been a 2 stoke as you could see the cylinder my dad said it worked like a diesel. As a curious observer it would be As a curious observer it would be nice to see these running. :)
I absolutely LOVE nitro
Well, put Bruce,
really good information as always... :)
I got my first cut in the finger when I was 9 :) After several cuts, I mostly resorted to starting-motors wich also are gently to wooden propellers unlike "chicken-sticks", even if padded with a soft hose out of rubber or plastic :) Chicken-sticks tends to loosen thin sections on the trailing edge of wooden propellers, not good.
A hard propeller back-stroke on the finger in -10°C is quite remeberable, so an electrical starter is the way to go, at least for the larger engines.
I start smaller engines with a chicken-stick wich is made out of a hard wood dowel with a garden-hose like hose on the outside, to protect the fiber-glass propeller. The whole thing is about 23 mm outside diameter and 200 mm long. Very effective.
Reason is that this smaller engine does not have a propeller-spinner for engagement of the electrical starter, for traditional reasons. However, I use a cheap O-ring in front of the propeller-nut, to hold the nut in place, in case of back-firing. Also very effective.
A benefit of Nitro or internal-combustion engines is that you can fly twenty-five or way more flying sessions on a beatiful day. Allmost impossibly with electrical power. Now you might learn how to land straight and good, with a beatiful three-point landing after many hours of training.
I think it is very fun to do a gently touch-down on the tail-wheel first. No nose-over :) Of cource the elevator-deflection is at maximum (+/-30°), center of gravity at the most rearward allowable position, and I am using strictly linear coupling between the stick-control and the elevator / rudder / aileron, also with helicopters as well.
Lets go real old school how about ignition engines foresters, olson and rice my dad had those back in the free flite days love your you-tube channels. As for tuning take off rich when the motor unloads it will lean out.
It will be awesome to see more about these engines and some gas or petrol too!
Fascinating! Thankyou
Extremely informative intro to nitro! This old glider flyer learned stuff he never imagined ;-)
I still run mostly nitro for the exact reason you mentioned last...fill it right back up, and you're back in the air. I love foam edf's, but other than that, nitro or spark/gasoline for me.
My Old MERCO 61 Marine would only run about 9-10,000 rpml, but had a ton of torque for running large props. (HUGH FLYWHEEL)... I ran a water jet on a large heavy "Tug"lllllllll'..... very reliable. Mainly in the off season (winter)
Cheap OS Max .21/.35's and .0.40's with bushings not bearings. throw aways, lols........
Oh Dear, nostalgia!
Well, you forgot to mention that those engines were very expensive at the time. I just read the magazines over and over, but never was able to purchase one...
The really hard core engines, were the star configurations you would find in some WWI type aircraft models.
Hi Bruce, good to see the old glow engines out. I have some old engines that my father gave me. One has never been used and the others haven't been used for 25-30 years. As you would guess they no longer turn over. I would love to see you do a video on how to free up and clean one of these engines bringing to back to life. Cheers.
My experience:
Remove the engine head and carb and dismantle as much as possible without doing damage to stuck parts. Throw everything into a bucket and submerge in nitro fuel. After 2-4 days things should start to move. Dismantle and clean the entire engine. The two engines I have fixed have both ran awesome after this cleaning method.
A great walk down memory lane Bruce. I still have some of these motors but haven't used them for years :) Regards, Pete
Every few minutes of this video I get to know not something new, but total game-changers in understanding of glow enginesĄ thank you!
Love to learn about setting the nitro needle valves
Jeez..all I fly is nitro engines..old school
Awesome Thanks for sharing Would be great to have a video on how to tune the engine. Also does the nitro engine need breaking? Thanks
What about the good old power panels. You can use a 12v battery to power the panel which then provides power to the glow plug and also provides power for your electric starter. I still love my nitro engines, I can't bring myself to part with them. YES PLEASE, do a nitro build video. It's been ages since I flew nitro, would love to see what has changed
This is so interesting Bruce! I never realized it was the reaction twixt fuel and platinum that ensured continued combustion.
Thanks for the education. 👍🏾🙂
I love the smell, sound and smoke of those engines, but totally hate the after flying part on airplanes which is cleaning the thick oil covering the whole airplane on the side of the exiting exhaust pipe :).
But they definitely make way more fun than electric, sadly glow fuel is too expensive here so I wish I had was a large 3D airplane with a proper nice racing petrol engine in it...
I've been given a couple of these. Time to have a go. Yeah. (I suspect it might pay to start it outside though !).
Yeah the exhaust can be quite the smell. Great outdoors, not so awesome indoors
Sounds like interesting fun will be looking out for the nitro build bruce👍👍
I love the idea of an actual "gas" powered rc car. The only thing I dont like about nitro cars is the sound because when I think of a 2 stroke engine, I always think of that gnarly 2 stroke ping from like a dirt bike.
Concerning glow plugs, my experience tells me to use a hot plug at elevations like Bogotá, 2650 meters above sea level. Normal or cold plugs at sea level. It also depends on the amount of Nitro Methane in the fuel.
I have a nitro 2 stroke I got for free. Might be time to plan for a build with it! Maybe out of foam tho...cause I’m still pretty lazy
yes please on build video. If you could, a setup or tuning primer would be more than useful as well!
Hi Bruce. Great video and review of nitro motors, I still have my nitro engines now I just need to find a balsa kit to build. Now everything is foam and RTF electric. I miss building a new plane in the winter months. Thanks for sharing your experience with nitro.
