Changing the Throttle Ratchet
1. Remove the eight Phillips head screws including the two
antenna cover screws that secure the rear transmitter case half.
2. Put the transmitter face down on a piece of foam or a towel
and remove the lower back case. Carefully pull the antenna
cover off the top of the transmitter and set the back case
aside.
CAUTION: Use care to not pull or disconnect any of the
wires attached to the back transmitter half.
3. Locate the silver throttle friction straps on both gimbals. One
strap engages a serrated section on the gimbal for a ratcheted
throttle, while the other strap engages the smooth section on
the gimbal.
4. To change the throttle ratchet, loosen the throttle strap so
it does not touch the throttle gimbal. Tighten the opposite
throttle strap to engage the desired throttle ratchet.
If you only need to adjust the throttle friction, see the Adjust
Throttle Friction Straps section.

Transmitter Mode Conversion
You can change transmitter modes among Modes 1, 2, 3 and 4.
This conversion requires both a programming and a mechanical
change.
Programming Conversion:
1. Access the System Settings menu from the Setup List and
select the desired Mode. If you are changing between Modes
2/4 or 1/3, you can STOP after Step 1.
2. Exit the System Settings menu to save the selection.
3. Power off the transmitter and remove the transmitter battery pack.
After you change the transmitter Mode in the Setup List, you will
need to make mechanical changes to the transmitter gimbals.
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.
Mechanical conversion is required to change between Modes 1 and 2 or between Modes 3 and 4. The mechanical conversion consists
of the following steps:
1. Change the Throttle Ratchet
2. Adjust the Elevator Centering Screw
3. Move the Throttle Limit Wedges
