I put a ported os 32 with tuned pipe in it. I have 225 mg servos in it with a 10x4 prop. It is light !! I had a enya 45 and the throttle was too slow to respond. I hovered it climbed decended and a little torq rolling it is a hard one to torq roll for sure. Thanks for all the help and yup it is doable after all.
