I've flown this YAK with the Fugi 43EI. Turns APC 20 x 8W 7000 or 20 x 8 at 8000. Well pleased with overall performance. Good but not great verticle out of 3D hover but ok most of other maneuvers. Starts easy and runs great. Also great value at Tower Hobby prices ... I paid $395 less $30 discount less a $40 merchandise certificate. It's not a 50cc but reasonably close depending on what you are looking for in pure 3D performance. Would definitely go with this engine over any glow.
