7. Install the throttle servo following the recommendation
of the engine manufacturer. IMPORTANT!! Many gasoline
engines, especially those with an electronic ignition, require
the throttle servo to be located 6" [152mm] to 10" [254mm]
from the engine. A generic servo tray for use on the throttle
servo is included to help mount the throttle servo. This is
where we located the throttle for the Fuji-IMVAC engine. You
may wish to install it here or in some other location
appropriate for your brand of engine. As a general rule,
metal pushrods between the throttle servo and the arm on
the carburetor are not acceptable due to possible transfer of
electronic engine noise between the engine and the radio
system. Nylon pushrods are generally a better choice.
Please refer to the instructions with your particular brand of
engine when choosing a throttle pushrod.

8. Install the ignition cut-off switch (refer to your engine
instructions for switch recommendations) as close to the
engine as possible. The bottom of the fuselage is a good
location for this. You may wish to create a small plywood
mounting plate to mount the switch to the fuselage.
The fuel tank included with this kit is suitable for use with
glow fuel. However, if using a gas engine, the fuel tank must
be converted to work with gasoline. This can be done by
purchasing a Sullivan #484 Gasoline/Diesel fuel tank
conversion kit (SULQ2684), a package of Du-Bro #813 1/8"
[3.2mm] I.D. fuel line barbs (DUBQ0670) and 3' of Great
Planes gasoline fuel tubing (GPMQ4135). Without the fuel
line barbs some types of gas-compatible fuel line may slip
off the metal fuel tubes. If the Sullivan conversion kit is not
available the Du-Bro #400 gas conversion stopper
(DUBQ0675) and one 12" [300mm] piece of K+S 1/8"
[3.2mm] soft brass tubing (K+SR5128–box of 5) could also
be used to make the conversion.

1. Assemble the fuel tank as shown in the sketch. When
tightening the center screw be sure not to overtighten it. You
just want it snug enough to pull the rubber stopper tight
against the tank.
