I have electic foamies and that is the perfect solution for that size of plane. When you get to the .40 + sized, I'd prefer to run a YS .63 versus charging large batteries. The "result" of electric power is great - I personally don't like the battery management process of it all though. I place a premium on fuel-n-fly and longer flight times per flight. There are more and more notes coming out regarding people changing bearings - or finding other ways to work on electric motors. The ESC pops from time to time. The Batteries puff cells from time to time. This all equates to "work" that is done to the motor system. Once you put it all together, I really do not see the advantage versus the PIA of it all. I'll take my lumps or risks running YS, and others will take their lumps and risks running eletric. Deadsticks or low power output flights can happen to each system.

Its a little like game improvement golf clubs. All the "increased technology" hasn't resulted in a world wide phenomina of lower handicaps and better rounds of golf. Nor does electric help you score better maneuvers.
Thanks,
