I spent quite a few years as a test engineer for the full-size things. We had something similar happen with a starter (well, starter/generator). Only it wasn't plastic housing, it was magnesium. When it failed, we got a 4 foot bolt of lightning and a giant flash of blue-white sparks and then the vibration sensors all went insane as the motor tried to shake itself apart.
R/C Turbines are by far the coolest things ever. I've loved airliners since I was a kid and just the thought of being able to strap a small jet turbine to an R/C vehicle is incredible.
The startup sound, running sound, and the sound a giant engine makes at takeoff power is probably what drew me to aviation. I love being on the ramp when a 777 is starting up those massive GE 90 engines!!
As A.J.Foyt once commented, "If you can't afford to pop em, you can't afford to run 'em." I do think the design of the starter can be improved. Reliable override cluch and heat resistant case would be good places to start. Engines like this should have single fuel single button start because most people do not know how or why to properly start these things. The savety errors are obvious so no comment needed.
Watching this video again, after a while. I remember this mishap! Just before watching this, I happened upon a few guys enjoying their RC planes in a field. I just had to stop and chat. One of them had just bought a Jetcat just like this one. No shit, the propane hose failed. In my car, I had a meter of nice rubber hose, the right size. I'm an old school mechanic. We got the beast running. I was very impressed at the automation, the controller went into cool down mode. Yes, I cringed at the starter housing being formed plastic as well. Tell you what, it's mission critical that the starter clutch disengages. It's a brush type motor. Through software, the controller can disconnect the DC power, and watch that the starter has actually stopped! If it is locked, it's a wee generator. In this case, the controller could be programmed to do an emergency shutdown and cooling cycle.
I’m not normally a mechanical sympathy kinda of guy, but that time I felt bad. I guess you need a fire extinguisher and a leaf blower just in case with these.
@@H3110NU or monitor the starter motor leads for voltage once the engine is running. A motor being driven generates a voltage. If you see a voltage across the motor wires, the clutch didn't release and the motor will quickly fail due to being spun at a rate far in excess of its designed maximum RPM.
It's for my upcoming episode, but I ran into some serious engineering challenges with what I built. I'm putting on the final details today and hopefully going to finish filming the episode tomorrow. I think everyone's going to really like it
As a certified jet engine mechanic, I say the compressor blades can be blended( filed down to a smooth contour, I can help you if you need). You dodged a bullet when it seized, since when the engines are hot like that they tend to expand and contract when suddenly thermal shocked, permanently welding them shut.
In order for this to be more efficient it would need to run a higher compressor dischsrge pressure which means it would run s lot hotter so either itd have to be like a quarter a million dollars to pay for all the r and D to do things like super alloys, film cooling,blade tip clearance control, multiple stages, the whole shebang or it would run slightly more efficiently until it melted itself down, this is a very simple jet engine with just one stage of compression and im pretty sure 1 stage of turbines
Thank you for always looking to showcase such an interesting swath of things/mechanical based machines and functions. I am always glad when your channel is growing. You show people that even mundane things can be very cool to watch when shown in proper perspective.
@@snowcow1173 nop, these are called impelers, and are much more sturdy to the rotor simply because they are one piece, in axial flow engines the ailfoils are mechanically atached, those are more durable as long as there is a proper technician behind it. however centrifugal flow are less likely to fail, specially under extrange object introduction, thats why they are used in choppers despite its lack of power compared to an axial flow
I've been involved in both the industry and hobby-side aspects of turbines with a few different companies. Turbines are an investment in money, certainly - but more importantly, they require a massive investment in time, patience, attention to detail, and CORRECT EQUIPMENT, KNOWLEDGE, AND PROCEDURES. They are not things to ham-fist together in a garage. Anyway, happy flying.
I've had many turbines with no FOD guard. One quick trip to the dollar store to buy a small metal strainer to modify as a FOD guard has saved my turbines in the past.
I'd like to have the youtuber "AvE" have a tear-down commentary on this. "...The hand-blender was playing finger-cuffs with the starter until she had too much and decided to make a run for it"
I have to admit, that was the one of the most enjoyable TH-cam video that I have ever seen! I haven’t seen a jet engine demonstration since I was at the Museum of Science and industry by Exposition Park when I was 10. Thank you for the Great Post. Really loved it! 😁
Just get the jetcat pro turbines. They are way better. I made my internship there. The factory is next door. The small turbines have the starter in front, because there is not enough space inside. That it is plastic, is just stupid. I am looking forward to see more jet engine videos in the future.
I already started to redesign the starter mechanism I'm going to come out with my own version for these engines. I thought the junk cat pro turbines were set up the same way?
@@WarpedYT ok, thats impressive. You put a lot of work into your videos. The big pro turbines have a different Starter system. As soon as I got enough money, I want to put one on my bicycle. Maybe this is also something, you can try.
The thing of a jet engine is that it is a high powered vacuum cleaner and anything that is too close to the inlet is gonna get sucked into it and the end result is damaged turbine blades. Worst case scenario is that the whole jet engine shells out. I've seen it happen when I worked on the flight line with the Air Force. I was an aircraft crew chief and I saw that happen on more than one occasion. I can tell you from experience that it is plenty ugly. You got lucky with this incident that the front rotor blades were the only ones damaged. Good video!
The throttle response on turbines is definitely a learning curve. I have a good friend down in Chicago that I fly helis with, that flew a turbine helicopter in a 3D competition last year, and was able to show the power they can provide....in the right hands. You should seek him out to see what a turbine heli can do.
Yes absolutely the throttle response is much different it's kind of like PID, steering a ship principle. But the smaller you go the faster the response No doubt.
I turned the gain way down in editing...like way down, the sound is unbearable and the larger turbine that I have which I did not run in this video, literally shakes the ground.
Near where we live, there is an airfield with a road that goes behind the departure takeoff end of the runway (the roads have railroad like crossings on them to stop cars from flipping.) And me and my dad got to hear a lier-jet engines spool up and takeoff, it's honestly amazing, once in a lifetime opportunity to hear one.
The clutch is exactly what failed. I had a clutch fail on a real turbine engine years ago (a J-57 ) and while there was no FOD damage, the starter/clutch became a very good door stop.
Sad to say, but he kind of did everything wrong. Should have had the compressed air ready to go from the beginning, which should have been immediately introduced once cool-down failure occurred. He also had inadequate butane fittings. That motor is cooked.
@@edmartinelli If the problem is that the starter clutch failed to release, it doesn't matter whether the starter was powered or not. The engine overreved the starter. On the other hand, if the problem is that he kept the starter engaged after the engine was running at speed, then he likely caused the starter to overrev. He didn't seem to be very prepared to fire this engine up, as he had the fuel tank right up against the engine itself, and as others noted, he didn't appear to have a fire extinguisher in sight, and the exhaust was pointed directly at a car. If the engine had grenaded, shrapnel would have pelted the car. Also, it didn't look Still, I feel bad for him. That was a really expensive toy.
No eye protection either, and I don't see a fire extinguisher in sight. I totally understand the urge to jump right in and play with new toys, but I've learned my lesson over the years.
I watched it fly off when you asked him to run it up to full speed. He's gonna have to blend those blades in the first stage also. With 3/4 million views from this video I hope you contributed to the new engine.
Good luck getting any kind of respectable service from them in Va Beach!!! I literally GAVE my Jetcats away and replaced them all. Never had a problem since!!! Good luck ya'll.
Same thing happened to my '73 Mustang once. The starter motor stayed engaged and got destroyed. Fortunately with a piston engine, it doesn't damage the rest of the engine, like it did here.
Great video. I think every junior and senior high school in America should have classes and these engines on site. No learning can compare to hands on learning. Thanks for this awesome article
Every single modern “model” turbine engine is started by a front mounted motor. Clearly the bendix clutch didn’t disengage and over sped the start motor. Normally it would disengage after the ignition. Also highly recommend that you run them with the FOD screen fitted. 👍
Completely agree, and I knew that comment was coming, however that is not what I meant I cut out some of the parts of what I said because I like to keep my videos clean. You can use your imagination but I am going to redesign it
@@WarpedYT I look forward to seeing what you come up with :-) that Jetcat design is not as strong as more modern types, I had a starter fail on my 160sx. Now prefer Jetmunts, brushless motor and a much sturdier design on the starter among other things. Great videos, keep them coming. 👍👍
@@AliceC993 I know what he thinks. I am just tired of people talking about scaled down versions as if they are not real. Or just Toy's. There is absolutely no part of a scaled down Turbine that is a toy!
Something they could have easily done in the engine controller, the starter shouldn't be generating power long after it disengages... however some hobby sized jet engines use a starter that doubles as a generator and remain directly attached to the turbine during operation.
The first start of the first jet engine in 1937 in Lutterworth where I live ended badly as well. Frank Whittle built it on a trolley and just in case it worked, he built the engine on a trolley and bolted the trolley to the brick wall of his workshop. The engine fired up with far more power than he thought it would produce. It ripped the bricks out of the wall leaving a gaping hole, and the engine and trolley shot across the room and smashed to bits against the opposite wall. He showed it to the RAF suggesting they could put it on an airoplane. They said no thanks, it hasn't got a propeller. It would have been quite useful in WW2 . . . . . .
There where probably a number of reasons it was rejected. Frist one I think of would be new tech 2 years to test and then produce jets. They where probably also afraid of another dreadnaught situation. I can imagine that completely redesigning the sup0ply chains for all bases, jet engines need a different fuel to run then prop. Then there is the expected enemy, do you need a plane like that to fight the Germans etc. There are examples of prop planes shooting down jet craft. Would it have been a major upgrade to the Royal Airforce I personally don't think so keeping something good enough building it in numbers and being simple to train people in its use are key points.
@@rascototalwar8618 Germany had the Messerschmitt Me 262 by the end of WWII. Other planes were in development including jet bombers. Had Germany been able to continue fighting longer, or developed jet power quicker, it could have quickly rendered propeller driven planes obsolete with the Allies several years behind trying to catch up.
This is why sometimes when doing the first start of "big" jet engines, they will hit the kill switch pretty much as soon as the combustor lights and then check for any signs of trouble before performing a longer run.
This reminds me of when I was in the Air Guard and got to go out to the test stand where they had an F-100 set up to do an engine test. They started the J-57 engine, idled it for a while and then ran it up to full military power and then lit the afterburner. I had ear protection on but standing right next to it while it was running was still probably the loudest sound I've ever heard.
If this was "start it up now for the first time", then how come at 0.17 you can see the hole in the casing, but then it fixes itself at 0.54, wow, what an engine
My thoughts exactly. I don't know anything about jet engines, other than they spin extremely fast with a lot of centrifugal force and if anything fails, parts could fly. I would have done the test inside a protective housing, just to be safe. I saw off center heating on the tail end, a fuel puddle underneath, and the fuel tank near the intake. Based upon the title, I was expecting he whole thing to blow up in their faces.
The sound of the jet engine is awesome! Looking forward to future episodes!!
It probably sounds even more awesome installed into a model airplane during a fly by.

I know nothing about RC jet engines but I would never park my car right behind the jet exhaust.
Or in a large glass flask!
It would be neat to see the air flow with a little smoke ahead of the intake. Thanks for the vid. guys.
On a real jet you'd get a NO STARTER CUTOUT caution. And if the starter explodes it's not pretty for the engine cowling
That is for sure I haven't seen that in person yet but I can only imagine
@
Nick Steffen This isn't a real Jet?? I wonder what we are looking at then...
@@ThunderPantz01 he's implying a full-size jet used for actual aircraft, as opposed to a scale engine for R/C craft
@@AliceC993 I know what he thinks. I am just tired of people talking about scaled down versions as if they are not real. Or just Toy's. There is absolutely no part of a scaled down Turbine that is a toy!
Something they could have easily done in the engine controller, the starter shouldn't be generating power long after it disengages... however some hobby sized jet engines use a starter that doubles as a generator and remain directly attached to the turbine during operation.
Really cool to watch!
You need to fit a Foreign object catch screen around the intake. That would stop that sort of accident happening again.
Nice video man! 👍🏻🤗😁
Love them jets
The first start of the first jet engine in 1937 in Lutterworth where I live ended badly as well. Frank Whittle built it on a trolley and just in case it worked, he built the engine on a trolley and bolted the trolley to the brick wall of his workshop. The engine fired up with far more power than he thought it would produce. It ripped the bricks out of the wall leaving a gaping hole, and the engine and trolley shot across the room and smashed to bits against the opposite wall. He showed it to the RAF suggesting they could put it on an airoplane. They said no thanks, it hasn't got a propeller. It would have been quite useful in WW2 . . . . . .
There where probably a number of reasons it was rejected. Frist one I think of would be new tech 2 years to test and then produce jets. They where probably also afraid of another dreadnaught situation. I can imagine that completely redesigning the sup0ply chains for all bases, jet engines need a different fuel to run then prop. Then there is the expected enemy, do you need a plane like that to fight the Germans etc. There are examples of prop planes shooting down jet craft.
Would it have been a major upgrade to the Royal Airforce I personally don't think so keeping something good enough building it in numbers and being simple to train people in its use are key points.
@@rascototalwar8618 Germany had the Messerschmitt Me 262 by the end of WWII. Other planes were in development including jet bombers. Had Germany been able to continue fighting longer, or developed jet power quicker, it could have quickly rendered propeller driven planes obsolete with the Allies several years behind trying to catch up.
Your engine fod -ed out man, major drag. Cool engine. Better luck next time man
This is just tragic. That is a great motor, i have the same one.
I like the new friend, 2k for a jet engine isn't bad!
This is why sometimes when doing the first start of "big" jet engines, they will hit the kill switch pretty much as soon as the combustor lights and then check for any signs of trouble before performing a longer run.
Well if big jet engine is unbalanced, physics is gonna take its course sooner or later.
"It's tight now"... Can't help it. LMAO. Reminds me of all my foibles.
Legends say, he still asks "Why didn't it go into cooldown mode" 😂
This reminds me of when I was in the Air Guard and got to go out to the test stand where they had an F-100 set up to do an engine test. They started the J-57 engine, idled it for a while and then ran it up to full military power and then lit the afterburner. I had ear protection on but standing right next to it while it was running was still probably the loudest sound I've ever heard.
If this was "start it up now for the first time", then how come at 0.17 you can see the hole in the casing, but then it fixes itself at 0.54, wow, what an engine
You sir have a great eye.
@@SuperDaleski1 I had my earphones on, the amazing realistic sound of the engine took my ears away, resulting in my eyes going in super-optic mode :-)
I’m so sorry your breaks my heart to see failures my best wishes for you my friend
May I suggest a Balsa-Flyer and a rubber band!
I lived a on a downhill street and that thing got some distance. Miss those.
Good job on the repair and explanation, yeh I've got to get one ; )
For a test of the engine, the guy didn't seem at all prepared to deal with any sort of failures or issues. Chance favors the prepared.
My thoughts exactly. I don't know anything about jet engines, other than they spin extremely fast with a lot of centrifugal force and if anything fails, parts could fly. I would have done the test inside a protective housing, just to be safe. I saw off center heating on the tail end, a fuel puddle underneath, and the fuel tank near the intake.
Based upon the title, I was expecting he whole thing to blow up in their faces.
Yeah, that's exactly where I would stand too while it is running. Directly in front of it. Lol!
