Default RE: airfoil max thickness position

It is angle of attack that stalls, not airspeed. You have too much elevator throw for the CG. The further back the CG is, the less movement you will need. If it's flyable as is, I would suggest just reducing elevator travel until it no longer snaps (although for an aerobatic airplane, snapping is somewhat desirable). Perhaps just a dual rate?
