Spaceclam,

I'm going to take the safe road and say, "No." This is just one of the aircraft's peculiarities. Part of its "personality", if you will. It is how the aircraft responds when being asked to perform outside its flight envelope.

In order to change something to fix this trait, you have to know exactly what is causing it. If you can figure out what is causing the right wing to stall before the left, then by all means you can do something about it... but without knowing exactly what is causing the behavior, and throwing "fixes" at the symptom, you risk ruining the otherwise good flying characteristics of the aircraft. Throwing "fixes" at an unknown problem is risky at best.

My advice would be to leave the airplane as is... and know that if the airplane is going to snap out on you if you make a hard fast pull.

Also, I would try playing with the rudder trim... put in 1 or 2 or a few clicks of left rudder trim and see if the airplane still snaps. It really could be as simple as that.
