13. Temporarily connect the throttle servo to your radio
system and turn on your transmitter to test the operation of
the throttle. Moving the throttle stick down to the idle position
should close the carburetor leaving approximately a 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. Adjust the position of the pushrod
in the screw-lock connector as necessary so your throttle
matches the pictures.
❏
14. When you wish to shut off the engine using the
transmitter, you can either use the throttle trim button to close
off the opening in the carburetor barrel completely or you
can set up your transmitter with a “throttle cut” switch (most
computerized radios have a throttle cut feature). The throttle
cut switch is a toggle switch or button on the transmitter that,
when activated, will close off the carb barrel completely in order
to kill the engine. The carburetor will return to its original idle
position (the 3/64" [1.2mm] opening you set when positioning
the pushrod in the screw-lock connector) when the switch is
released. Refer to your radio manual for details on setting up
a throttle cut switch.
