Reverse av/RCU poll

Okay, we can build em stronger, but what about the guys who fly ARF's?  Are
the manufacturers going to change the way they construct their product?

I know there is a lot of what if's, but what if an engine craps right after
the snap, we'll be low and stalled, at least very slow. This could be
another contributing factor to loosing a plane.
