GA-250 Micro Gyro Manual Operation ← Move the rudder stick to high end Move the rudder stick to low end → Light Status ●● ●●● Gyro Direction Normal Reverse The gyro has two move directions, Normal and Reverse. Rotate the helicopter at least 90 degrees counter-clockwise, in an attempt to oppose the rotation and maintain the helicopter heading the gyro should have now moved the tail blades in the same manner as if right rudder was applied, the direction of the gyro is correct.
