I know that some guy lost an engine in an arrow and didn't engage the over ride to keep the gear up. lawsuit blamed the gadget instead of the engine or pilot.
I always thought it was a good idea. So, who knows what some guy has in his hangar.
oh, and to the OP
if you lose an engine (the engine) you can get better glide performance by pulling prop lever aft, but you propably (yes a joke) know this already.
