The airplane flies very solid and neutral for a small plane. Knife edge coulpling is almost non existant. On my 34% I think I'm only running 1% ru-aileron mix and 2% ru-up elevator mix, and 1% throttle to elevator mix that activates only in the last two clicks of the throttle stick to the idle side for downline tracking. The 27% is for the most part the same. The airplane in the video had no mixes at all because that was the second flight on it! It would be a very good plane to start IMAC with. Due to the small size it wouldn't be competitive in the higher classes but just fine for the lower classes. Don't get me wrong the plane is capable of the unlimited sequence easily, just the small size wouldn't present properly at that level. Snaps and spins are great with it. The plane is not setup for a pipe or cannister, but you can get a cannister to fit with some modification. I really don't think the pipe or cannister is nesassary from a performance standpoint, the only reason I would put one on is to quiet the plane down, but 50cc engines aren't all that loud anyway. The DA 50 or 3W50 both would provide excellent vertical performance!
