Yea, if it's stiff and twitchy, turn the gain down. You can leave the heli on while doing this particular adjustment. Tiniest amounts until it just goes away.

If You ever want the left turns to be as rigorous as the Right turns, You have to turn the pot down ridiculously low, but then You can't fly a straight path without the tail trying to catch up with the front; going all over the place, unless You do corrective inputs all the time.

I like the gyro working to make my flights more beautiful, and that means that My right spins are fast, and the left spins are noticeably, but not severely slower, that seems to give Me what I want.

If the gyro is too tight, it will also affect your left turning as well; it will take more stick and that gets Me into trouble running into walls.

Once You have Your preferrable style; You shouldn't have to ever touch the gyro again ( I did after replacing some weak motors).
