I lost two gas planes back to back last month and one might have been saved if I had a kill switch. All was going well until the muffler fell off my MVVS 1.60. I could not get the idle low enough to land the plane. Went back up and went into programming mode to bring the throttle ATV all the way down and that still wouldn't kill it. While waiting for the tank to run dry, the plane seemed to get pretty tail heavy and after a circiut or two, I lost signal and the plane went in about half throttle at a 45 degree angle. The assumption was that the RX battery came loose and then eventually disconnected. If I had the kill switch I would have gotten the plane down before the assumed battery issue took place. Would I have noticed if there was a problem with the batteries mounting condition for the next flights? Probably not. I will be putting a some type of kill switch on my next gasser. I doubt that I'm going to spend sixty bucks on one though. Just my two cents.
