I flew Jim's, the one smallfly spoke of, and it had enough power, but it wasn't any excess either. It would pull out of a hover pretty strong, but wouldn't jerk it up like I am used to. The airplane flies very well though. It will knife edge without any correction, and is very easy to hover. I will have to build one, someday soon. Until then I will just watch Jim's fly. He covered it like the one in the ad, and it does look awsome in a low knife edge with the canopy toward you.
