Quit *****in about the stock setup! The airplane has over 40 watts per pound and if you fly 'on the wing' it is fine. Yes, more power means more aerobatics, but you only need 30 watts per pound to fly. I've seen glow fliers (yes, I flown glow - lots) stall electrics into the ground because there isn't enough power (hint: quit pulling up elevator and stalling)

I'm putting the motor out of a Electrastar with A123 4 cell pack in a superstar ep. That's the set up used in the 5-6 pound electric into a 3 pound electric. Power is fun but low power flying is fun. Your saying something is bad, when it is only you don't know how.................
