Instructions
Disconnect the motors from the controller. Write down the location and polarity of your tail and main rotor wires, then pull them off your controller. While you're at it, make sure your battery isn't hooked up. When you reconnect the motors you can refer to your notes to hook them up the way they came off.
Set the transmitter to its starting position. Put your Idle-Up switch in "Normal" mode and center every control except your trim and throttle. Make sure they're in the down (off) position.
Arm and adjust the controller. Turn on your controller and hook up the helicopter battery. When the controller arms, set your throttle to 50 percent and your Idle-Up switch to "Idle Up" (it should be up towards the face of your controller).
Check the pitch of your blades. Turn the main blades until they're at a 90 degree angle to your helicopter and the flybar is stretched between the nose and tail. Put your pitch gauge halfway down on one of the main blades and as you look down the blade adjust your gauge until its top edge lines up with the flybar. Now read the scale and write down the pitch then do the same with the blade on the other side.
Disconnect the pitch control links. There are rings at each end of two pitch control links (one control link for each blade) and they're mounted on ball connectors. Use your fingernails to pop the rings off the ball connectors that are attached to the flybar mount.
Adjust the pitch control links. Twist the rings that you popped off the ball connectors counter-clockwise to lengthen your control links (if you need a more positive pitch) or clockwise to shorten your control links (if you need a more negative pitch). The direction you go will depend on whether you need to move in a positive or negative direction to set the blades to a neutral (zero) pitch.
Reconnect the pitch control links. When both blade bottoms run parallel to the "Paddle Control Frame," snap the control link rings back onto their ball connectors.
Recheck the pitch of the blades. Slip your pitch gauge halfway down one of the blades for a second reading and as you sight down the blade readjust the gauge until its top edge lines up with the flybar. If your gauge reads zero, check the other blade to see if it matches. You can turn off the controller and reconnect the motors if it does but if it doesn't, you'll have to repeat steps five through eight until you get it right.
