Installing the Muffler
The muffler mounting accessory package 
includes mounting screws (2), lock washers 
(2), muffler gaskets (2) and L- wrenches (3).
1.  Put a lock washer on each of the muffler 
screws. Push the muffler screws through the 
muffler.
2. Align the muffler gasket with the exhaust 
opening and the muffler mounting screws.
3. Tighten the muffler screws. 
IMPORTANT: Tighten the muffler screws after 
the first few tanks of fuel. The muffler screws 
may loosen from heat and vibration. After the 
third tightening, no further muffler loosening 
should occur.

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. Center the throttle servo. Install a servo arm 
with a hole 11mm (7/16 in) from the center 
of the arm.
6. Use a clevis to attach the throttle linkage to 
the servo arm.
