I have the same plane 50 sx power. Mine will also snap, but only when excessive elevator is applied eg, full up at med to hi throttle. I think most scaleish aerobats will do this. This has nothing to do with the "snap happy" reputation Caps got - that was a low speed handling issue which this model does not have due to built in dihedral. Just tone down your elevator inputs. You'll find this plane will harrier with great stability in calm conditions and does great elevators any time!
