How to Use the E-flite Pitch Gauge

The pitch refers to the angle of your radio-controlled helicopter's rotor blades relative to the ground. The larger the pitch angle, the more lift the rotor blades generate per rotation. The E-Flite pitch gauge enables you to measure the angle of your rotor blades to help you fine-tune your aircraft. Learn how to use your E-Flite pitch gauge to ensure your helicopter is achieving optimum performance.

Instructions

- 1
  Disconnect the motors from the radio system to prevent the blades from spinning while you assess the pitch angle. Unplug the wires that lead from both the main rotor motor and the tail motor.
- 2
  Slide the pitch gauge onto the tip of one of the main rotor blades. Move the pitch gauge to about mid-point up the length of the rotor blade.
- 3
  Turn on the vehicle and the transmitter with the left joystick positioned at idle throttle (which is when it is all the way down). Loosen the nut on the pitch gauge while orienting the flat edge of the gauge in parallel with the aircraft's flybar (which suspends the two weights on your main rotor shaft).
- 4
  Read the number indicated by the sliding pointer once the flat edge is perfectly parallel to the flybar. This is the pitch of your helicopter's main blades.
- 5
  Adjust the linkages leading to the rotor blade until the readout of the pitch gauge equals zero. Rotate the linkages clockwise to shorten the linkages; rotate the linkages counterclockwise to elongate them.
- 6
  Raise the throttle joystick to midpoint, then adjust the linkages to achieve the pitch setting for that position. Raise the collective pitch joystick to full and adjust the linkages to define that pitch setting as well.
