If I remember right (do a search to double check - it's been posted before) the pot near the front of the heli is the Gyro sensitivity, the other is the Tail gain control

Be careful when adjusting these pots - they have an end stop which you can break
Make sure you know the original position, before you adjust them


Turning the pot clockwise increases the gain


You don't need to remove all of the shrink-wrap, just use a sharp blade to cut a flap over the pot
