of the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected to
those controls. Be certain the control surfaces have remained
centered. Adjust if necessary.
Check the Throttle Operation
❏
1. Turn on the transmitter and receiver and center the
position of the throttle trim lever. Move the throttle stick to the
idle position (toward you) and look into the carburetor. The
carburetor barrel should reveal only a small 3/64” [1.2mm]
opening as shown that will keep the engine running at idle.
Moving the throttle stick up to full throttle should open the
carburetor completely.
❏
2. If the carburetor does not respond as shown in step 1,
loosen the cap head screw that secures the throttle pushrod
to the throttle servo and adjust the position of the pushrod in
the screw lock pushrod connector so movement of the carb
matches the photos.
❏
3. In order to shut off the engine using the transmitter, slide
the throttle trim lever all the way down. This should close the
carburetor completely as shown. If closing the carburetor
completely does not shut off the engine, pinch the fuel line
that connects to the needle valve until the engine stops. Before
running the engine again, determine why the engine would
not stop running using the throttle trim lever. If you are sure
that the carburetor closes completely, an air leak in the fuel
line or around the carb body is probable.
