I managed to accidentally kill the engine in flight today with a friends Comp Arf. He has one of those damn choke servos set up on a switch by the rate switches. Landed fine and all worked out in the end, but that's precisely why I won't have a transmitter activated engine cut except via the throttle trim. Hit that switch just one time while in a hover and see what you end up with. The only other method I'll use is the ignition switch on the side of the plane. Those two are ALL that is required by the IMAA.
