Hook Up the Throttle
Refer to these images while hooking up the throttle.
❏
1. There are four throttle servo mount locations available.
Determine the location that makes the straightest run for the
throttle pushrod from the servo to the carburetor arm (keeping
in mind that the fuel tank will also be installed). Use a 3/16"
[4.8mm] K&S brass tube sharpened on the end or a 3/16"
[4.8mm] drill to drill holes where necessary for the throttle
pushrod guide tube, or use the existing hole in the front
former if your setup is the same as the one illustrated here.
❏
2. Mount the throttle servo in the servo tray location
chosen. Cut the throttle pushrod guide tube to the correct
length and roughen the outside with sandpaper so glue will
adhere. Install the guide tube, but do not yet glue it in.
❏
3. Bend the throttle pushrod as necessary to connect to the
servo arm and the carburetor arm with the hardware shown.
❏
4. A lite-ply “U” brace is included for stabilizing the end of
the throttle pushrod guide tube. Cut the brace to the length
required, then glue into position. Glue the throttle guide tube
into place as well.
Install the Fuel Tank
❏
1. Glue together the two plywood fuel tank neck rings.
Then, glue them to the back of the fi rewall aligned with the
hole in the fi rewall.
❏
2. Loosen the screw in the stopper in the fuel tank and
take out the stopper/fuel line assembly. Check to make sure
the clunks are present and secure on the lines and that the
vent tube is pointed up toward the top of the tank. Also make
sure the lines on the clunks are not so long that the clunks
can contact the back of the tank (and possibly become stuck).
Make any adjustments necessary. Then, reassemble the tank
as shown with the vent tube at the top of the tank. Make
sure to securely tighten the screw to expand the stopper
sealing the tank.
