Just keep stick movements SLOW. The reason is you can aggrevate a stall if you start ramming the sticks.

I flew and busted up 3 or 4 trainers but had a TON of stick time. Went from that to an extra 300. Many say you can't do this, but I'm tellin ya, the whip crack control rocked! (let alone the enjoyment)

Remember, SLOW and EASY.

Good luck, and don't give up. (I don't think you will)
