thx very much, i think i should do that, today's too windy for me to fly outside, so i'll just ripe it apart and do all those things. and oh ya, i didnt notice this before either, that my tail is wagging, not really side to side as if the gain's too much, but rather wagging up and down, ya, i no, its weird, but i'll change the main shaft and motor to see wat happens.
