RE: Sig Extra 300XS
Propace,
I have this plane with the OS 1.60FX on it.
I have not really tried to do a lot of 3d manuevers with it, but I also do not think that this is the right plane for 3D.
It turned out a little heavier than I would have liked (about 14.5 pounds) and the control surfaces are not quite large enough, especially the elevators.
The plane does a really good flat spin on high rates, but I have yet to be able to get it to do a nice elevator.
