The bias only adjusts difference in turn rates left and right. The bottom pot adjusts the yaw - turn the pot in the direction of the yaw rotation - if the heli turns right, turn the pot right (small amount at a time.) The pot in the middle is gyro gain - how sensitive it is to yaw movements.
the Gyro gain is the weird part when it is in the air it pulls hard to the left nose first so I move the aileron stick to the right to compensate the tail motor and it seems in the air it doesn't move to zippy because it is at full speed now as soon as I initialize the heli it starts to rip pretty fast and in mid air it is like maxed right out.
Or it cuts out all together as you can see in the video
