GP Ultimate Owners, Help!
I have the .72
Great flier, but it is too heavy to hover with the 72, it takes almost full throttle.
It is a shame that GP uses balsa that heavy. I'd like to scratch build one with light balsa and FG cowl and pants, I bet you can spare up to 1lb!!!
The 91 would be fine but you'll have to work with the throttle. The airframe is very strong. Too strong for a .40 plane, in my opinion-> that makes it so heavy.
Good luck!
