1st Start of RC Jet Engine Ends Badly

We start up a few JetCat turbines and have a Failure on the first engine almost right away, looks like the starter clutch fail to disengage and the starter oversped and broke apart.

I then take the JetCat turbine apart and the starter to see what went wrong, then we start up 2 more turbines after that.

This is about 14 minutes of non-stop jet engine action hope you enjoy.
I figured I would do some videos with these little jet engines since almost everyone enjoys these little jet engines and my friend wanted to bring them over and mount them to my stand to test them.

Personally I love hearing these engines and seeing these engines run.
I just can't get enough of seeing jet engines run there's something about it, so hopefully you enjoyed this video let me know if you want some more

Watch this in 4k when possible, it looks incredibly awesome !

The sound of the jet engine is awesome! Looking forward to future episodes!!

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.

Normally seeing mechanical destruction makes me smile (fix enough so its therapy to me), genuinely felt bad on this as one hell of a toy

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!!

When he said “it’s gonna go into cool down mode, and we heard the turning CREAK to a halt, I knew something bad happened

[cyancoyote]

"Look at the compressor wheel, it's damaged!"
"That blows!"

No it doesn't he just said it's damaged. It does anything BUT blow.

[chrisnielsen]

Oh no you can hear the utter dismay in his voice when he said it was supposed to cool down and it screeched to a halt 😪

I love the comically oversized flask as a fuel tank on the side!

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.

That’s why those metal shields on the front of the engine are so important!

I love the way with the smaller jet engines, you can literally watch the fuel levels dropping. Scaling them up definitely makes them more efficient!!!

[Taydrum]

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.

This engine is both adorable and menacing at the same time

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.

What a time to be alive, jet engines with such power have shrunk down to this size, crazy.

[esra_erimez]

I felt so bad for him when it didn't go into cool down mode. He sounded so sad.

Sherlock: Let's make the best of it.
That is an example of an easy going, good natured man.

[KSPilo]

A demonstration of a "birdstrike"...thanks for showing us. 😅

[ryanzanow]

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.
