Starting Procedures

When starting the engine the first time and during break-in it's recommended that you run
the engine without the cowling. Also, for safety reasons do not adjust the carburetor while
the engine is running. There are two recommended ways to start the RCGF 40cc twin:
A. Manual Starting
Note: When hand starting the RCGF 40cc twin, use a thick glove or heavy duty starter
stick to protect your hand.
1. The propeller should be installed on the drive washer at the one o'clock position and at
the beginning of the compression stroke so that it's comfortable to flip it through
compression.
2. Have someone help you hold the airplane while you start the engine.
3. Switch the ignition to ON, close the choke on the carburetor and open the throttle
slightly from the idle position.
4. Flip the propeller counter clockwise several times briskly, until a popping sound is
heard. This indicates that the engine is firing.
5. Move the choke lever to the OPEN position.
