I did this twice with my 30. I'm hopping I have it out of my system now that I'm flying a 70

If you jump on it quick enough you don't always smoke the liner on the 30. I hated pulling the fuel line, you know whats coming when the engine leans out

I think I read somewhere that its best to pinch the exhaust deflector. It will kill the engine almost immediately and no lean out. Can anyone confirm this

BTW another thing I had to learn the hard way. Always place the field-box on one side of teh heli and the radio on the other. This way the starter cord (for those who have yet to go cordless

) will not move the throttle or flip switches by accident.

Do you mean the back pressure line? I think that would be even slower to kill it and I certainly don't think it wouldn't not lean out. You're still just indirectly stopping fuel from reaching the engine.

Been there. I heard the "funny exhaust note" , but did not put 2 & 2 together. I was holding the blade root and it folded over nearly guillotining my fingers.

I hit the pinch shut off, whew!!!!

The shoes are definitely toast. They will be twisted and tweaked.

Just replace the liner and shoes together, and have peace of mind.

No distractions, tell people to go away, talk your ritual out loud, step by step. No matter how silly you think you sound. LOL.

If your mate is quacking at you about his latest exploit, tell him politely to "go away!!". I am deliberate to the point of being rude , when I am in pre-flight mode. Come up on me during it, and you get the Archer (old elbow).

Sorry, Nelly. Nevermind the bollocks.

Wanna hover??? Buy a helicopter.

No, I mean the exhaust deflector at the end of the muffler. I thought I read somewhere on the board that this stops the engine quickly. The idea is to stop the engine from breathing by pinching or flipping the deflector up and restricting the airflow but I have never tried it. I'm not sure how effective it would be at full throttle. Just wondered if anyone had any experience with this.

Pinching the deflector will stop the engine quickly.
My problem on the R90 is getting to it quick enough, as it always feels like I need to go over the heli

Been there done that too

When pinching the exhaust deflector it took awhile for my engine to stop. I think that next time I'll go for disconnecting the fuel line - no fuel, no go.

Having my heli: Cool, Having a working heli: Awesome, Having a day to fly: PRICELESS!

An incident that took about 3 sq inches of skin of the palm of my hand and nearly my fingers too..... Started a gasser heli that had an 8-hp twin in it. Throttle was inadvertently bumped just above idle, but the clutch engaged and nearly ripped my hand off. Fortunately the radio was easily within reach of my free hand so I could quickly hit the kill switch. No way could I ever hold back that rotor. Went back to the designer and insisted on a rotor brake mechanism for starting. Now, once the motor is safely started, the brake (pin) is removed for normal spool up.
It wasn't my first hot start and may not be my last. Of course I will endever to minimize the possibility of haveing another.
