Adjusting the Elevator Centering Screw
When changing between Modes 1 and 2, or between Modes 3 and 4, you must
adjust the elevator centering screw.
1. Hold the Elevator or Throttle stick
in the full up or full down position
when you are adjusting the elevator
centering screw. Holding the gimbal
stick reduces the load on the elevator
centering mechanism and makes it
easier to adjust the centering screw.
2. Locate the gimbal where the elevator
centering spring is engaged. Use a
Phillips screwdriver to tighten the
elevator centering screw. Tightening
the screw will disengage the center-
ing spring.
3. Using a Phillips screwdriver, loosen the opposite elevator centering screw until
the lever engages.
Re-assembling the Transmitter
1. Put the back of the transmitter case on the main case, taking care to not
pinch any wires or the rubber grips.
2. Install and tighten the four Phillips screws.
3. Install the top of the rubber grips on the transmitter.
Moving the Throttle Limiting Wedges
Throttle limiting wedges are used to limit the maximum throttle travel. When
changing between Modes 1 and 2, or between Modes 3 and 4, you must move
the throttle limit wedges.
1. Use a Phillips screwdriver to remove
the throttle limiting wedges from the
current positions.
2. Install the throttle limit wedges on the
opposite gimbal.
Adjust Stick Tension
Adjust stick tension using the screws on the stick gimbals through holes in the
back of the transmitter.
1. Remove rubber plugs from holes marked with a vertical arrow or a horizontal
arrow.
2. Turn the screws in these holes a small amount using a small Phillips screw-
driver to adjust tension on the vertical and horizontal gimbals.
NOTICE: Always do a test of stick tension while turning these screws to ensure
stick tension is not too loose or too tight. Tightening a screw too much can dam-
age a spring. Loosening a screw too much can let a spring fall off and cause
short-circuit in the transmitter.
CAUTION: Always power off the transmitter, disconnect and remove the
battery before adjusting stick tension or friction straps. Not doing so could
result in property damage or injury.
