GA, pretty much what Bruce said and for you I would say engine off and controls to neutral. A lot of my flying has been at IMAA events with huge crowds of spectators, I don't compete but I go to A lot of IMAC and racing events. For me flying out at the lake bed it's no big deal at all but flying anyplace there are people is another story. At A pattern event there are spectators and A full pit area, if you loose the engine and then regain signal for one reason or another then you are just dead stick. Just better to be safe the sorry. I have seen big planes go completely out of control, mostly without fail safe, sometimes it would have helped, other times not at all.
