I've got a magic with a TT36 heli on it, and its awesome. Wayyy beyond unlimited vertical with an APC 11/4. I used the stock heli pipe, which I think is tuned a for a lil more power in the midrange area, rather than a tuned pipe which will give ya more overall power. Do a search on threads on the Magic, and one of them shows all the mods I made on mine. It is a great daily flier, and its fully capable of scaring the poop out of ya.
