Reverse av/RCU poll

I lost a perfectly good plane one time in an old Masters sequence that had 
the square loop with half rolls. I had no idea the engine was dead until I 
started adding throttle as I was doing the last half roll on the bottom. To 
make matters worse, I was in a straight crosswind blowing out. I pointed the 
nose right at me but couldn't make it back to the field, touched down in the 
tall stuff and busted up the fuse and other assorted damage. Point in all of 
this is it's virtually impossible to design a schedule that won't leave you 
in a bad spot if the engine flames out at the worst possible time.
