Things You'll Need
Instructions
Hobby Helicopters
Fly your helicopter to assess the spinning, and to identify the position of the joystick that develops the most drastic rotation; in other words, the pitch of the blades changes as the throttle joystick moves from position 0 (idle) up through to position 100 (full throttle). It is important to note when the helicopter spins to make correct adjustments.
Enter the menu screen on your transmitter, then highlight the "Collective Pitch" option and press the select button. "Collective pitch" refers to the angle of the rotating blades and is directly related to reactive torque that causes the helicopter to spin.
Select the positon under the "Collective Pitch Settings" menu, then either increase or decrease the pitch. If your helicopter spins clockwise, increase the pitch; if it rotates counterclockwise decrease it. Make incremental adjustments, then fly the aircraft immediately after each change to assess for improvements. Continue to make adjustments to each problem position until the helicopter remains straight as the throttle is increased from zero up to 100.
Mini or Co-axial Helicopters
Fly your helicopter and identify the direction of the rotation.
Adjust the trim by pressing one of the two buttons located underneath the steering joystick on your transmitter. These buttons will either manipulate the forces of the two motors (one per rotor blade) or adjust the tail rotors directly.
Press the left trim button to correct a helicopter that spins clockwise, or press the right trim button to correct counterclockwise rotation. Make gradual adjustments while in flight to get best results.
Maintain a hover to test that the yaw is set correctly.
