1. Use a secure method to attach the
throttle linkage to the throttle arm on the
carburetor.
2. Power on the transmitter and receiver.
3. Move the throttle stick to the middle stick
position.
4. Adjust the throttle arm so the arm is 90
degrees to the throttle pushrod.
5. With the throttle servo centered, install a
servo arm with a hole at least 15mm (5/8
in) from the center of the arm.
6. Use a clevis to attach the throttle linkage to
the servo arm.

Connecting the Throttle Linkage
1. Lower the throttle and center the throttle
trim.
2. Adjust the length of the throttle linkage
until the throttle is open 1mm.
3. Move the throttle stick up to confirm the
throttle opens. If the throttle does not
open, reverse the throttle channel in your
transmitter.
4. Move the throttle stick and throttle trim
down to confirm the throttle closes.
5. If you reversed the throttle channel in your
transmitter and you are using a 2.4GHz
radio system, you must re-bind your radio
system to set the correct failsafe position.
You may need to adjust the endpoints on your
radio to achieve full throttle motion. Using
a longer servo arm will help obtain the best
throttle geometry.
Adjusting the Throttle Opening
Installing the Muffler
The muffler mounting accessory package
includes mounting screws (2), lock washers
(2), muffler gaskets (2) and L- wrenches (2).
We suggest using high-temperature RTV as a
locking agent on the muffler screws to keep
them tight.
1. Put a lock washer on each of the muffler
screws. Push the muffler screws through
the muffler.
2. Place the muffler gasket over the muffler
mounting screws.
3. Align the muffler gasket with the exhaust
opening and the muffler mounting screws.
4. Tighten the muffler screws.
