The differences are the canopy, frames, and tail drive. IMO its not worth the money for me personally. You can thrash the living daylights out of the cheap one and it will cost less money to fix.

The ones at are field are always tearing up the tail drive gear for stuff that wouldn't even bother a belt drive tail. And it always seems to be the one at the back of the frames that goes, not the easy one to change in the tail gear box.
