The board need to be firmly mounted near the center of gravity of the plane, by the double sided tape provided. Please make sure the longer side of the board is

along with the heading direction. The board must be leveled with the body of the plane. Please refer to the illustration below.

A3 Pro offers 3 fine tuning potentiometers to adjust the gyro gain for aileron, elevator and rudder (clockwise for increase, anticlockwise for

decrease). The best setting is determined by factors like fuselage size, weight and the power allocation used and so on. W e recommend

you put the gain to a lower volume for the first flight, then fine tune to get the best result. The adjustment will take effect immediately without

a restart. For your safety, please don ’ t adjust them until all the propellers become motionless.
