Throttle Ratchet Strip Installation
The transmitter is manufactured with a smooth friction strip and
the included optional ratchet strip may be installed if desired.
CAUTION: Always power off the transmitter, disconnect
and remove the battery before opening the transmitter
case. Not doing so could result in property damage or injury.
1. Remove the battery door and disconnect the battery from
your transmitter.
2. Carefully pull up the top of the left and right rear hand grips
on the back of the transmitter to expose the 2 case screws.
Tip: Only the top portion of the grip needs to be pulled back,
the entire grip does not need to be removed to access the
case screws.
3. Carefully remove and keep 4 screws from the back of the
transmitter (2 in lower corners and 2 under the back hand
grips).
4. Carefully open the transmitter case so no wires are
stretched or pulled.
5. Remove and keep 2 screws from the installed throttle
ratchet strip.
6. Do not remove grease from plastic part under the strip.
7. Attach the strip to the gimbal using the 2 screws.
8. Tighten the spring tension screw to get desired stick tension.
CAUTION: Make sure no wires or components are
pinched or damaged while installing the back cover.
9. Carefully close the transmitter case using the 4 screws and
re-install the hand grips.
10. Connect the battery to your transmitter.
Adjust Throttle Friction Straps
• Pull up the top of the rear grip on the back of the transmitter
to adjust the friction strip on the throttle gimbal. Only the
top of the grip must be pulled up to access the adjustment
screw, the entire grip does not need to be removed.
• Use a small Phillips screwdriver to tighten or loosen the
screw for friction strip.
• Reinstall the top of the rear grip after completing the
adjustment as desired.
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 damage a spring. Loosening a
screw too much can let a spring fall off and cause short-circuit
in the transmitter.
