How to Adjust the Pitch on a 4G3

The pitch on RC helicopters is adjusted at the swash plate, and the Walkera 4G3 is no different. Swash plate adjustments are a bit tricky, and knowing your way around the helicopter is definitely an asset. However, with the right instructions you can adjust the swash plate and set the pitch to the ideal level for more efficient and faster assents and descents.

Things You'll Need

Small Phillips screwdriver

Instructions

- 1
  Place the helicopter onto a flat horizontal space. Move the throttle and trim controls on the transmitter to the lowest position and aileron, elevator and rudder trims to neutral.
- 2
  Turn on the transmitter and connect it to the helicopter's power cable. LED lights will flash and servos will beep when the signal is received, and this will stop once adjustments are complete.
- 3
  Check to see if the swash plate, found directly beneath the main blades, is parallel to the helicopter's tail boom. Proceed to adjust the swash plate if it's not parallel to the boom.
- 4
  Disconnect the transmitter from the power cable and turn it off. Disconnect the power cable of the main motor and turn off the transmitter.
- 5
  Remove the screw from the bellcrank, the only screw found on the rotating serve, using a small Phillips screwdriver. Remove the bellcrank.
- 6
  Turn on the transmitter, reconnect it to the power cable, and wait for the adjustments to complete. Reinstall the bellcrank at a 90 degree angle and thread in the screw until snug.
- 7
  Adjust the swash plate by using a small Phillips screwdriver to wind the servo ball linkages, the vertical bars that connect the swash plate to the servos, up and down. Do this until the swash plate is parallel with the tail boom.
- 8
  Disconnect the transmitter, reconnect the main motor and take the helicopter for a test flight. If you still have pitch problems, reassess the swash plate angle and make necessary adjustments.
