There is a HUGE difference between a GT80 and a ZDZ80! Like over 3hp! and the zdz is alot lighter and is cheaper. Anyway, if you want to get into extreme aerobatics, youll want to sell that thing. Its worth its most right now when its new. But, the plane will hover, but will not pull out of a hover with authority. But will still be fun to fly, unless your power hungry like all of us!

Have fun!
