one on either side of the tank. With these in place, a #64
rubber band is hooked to one J-hook, pulled around the
tank and hooked to the opposite J-hook. With the tank in
place, use a pencil to mark the J-hook locations - remove
the tank. Glue two 1/8" x 3/4" plywood mounting pads over
the hook location marks. Use a twist drill with a 5/64" bit to
drill guide holes through the pads and fuselage supports.
Thread the hooks in place.
❑
8) Apply a bead of silicon adhesive around the neck of the
tank, where it contacts the inside of the firewall. Fit the tank
in place into the fuselage, pressing it firmly against the
firewall. Support the rear of the tank to the fuselage with a
#64 rubber band, using the J-hooks.
❑
9) Two throttle servo locations are provided, one on each side
of the fuselage. Choose the side that corresponds with the
throttle arm on your engine. Attach the grommets supplied
with your radio system to the servo mounting lugs and use
the mounting screws, also supplied with your system, to
mount the throttle servo.
❑
10) From your kit, locate the 1/8" OD x 18" nylon throttle tubing,
the 18" length of steel throttle cable, the die-cut 1/8"
plywood throttle tube support (small part with one rounded
end with a hole for the tube), the pushrod connector
assembly (3/16" hex brass body, nylon retainer and
4-40 x 1/8" socket head cap screw) and the 2-56 solder
clevis. Drill a 1/8" dia. hole through the firewall, aligned with
your engine's carburetor throttle arm. From the front, insert
the 1/8" nylon tube through the firewall and into the
fuselage, leaving 3" exposed in front of the firewall (typical
when using a 1.20 or 1.50 2-stroke engine). With the tube
in place, turn the fuselage over and note the location of the
tube in relationship to the throttle servo.
You want to
position the tube directly in front of the servo's output arm.
Assemble the pushrod connector to the servo output arm.
Slip the die-cut 1/8" plywood throttle tube support part over
the end of the tube, back to the forward fuselage former
location. Glue the support in place to the inside front of the
former, locating the tube directly in front of the throttle servo
output arm. Use a razor blade to trim the tube to a length
of 1" behind the die-cut tube support. Remove the tube
and sand its surface with 220 sandpaper to rough it a little.
Reinstall the tube and glue it in place to the firewall and the
die-cut tube support with thick CA glue.
❑
11) The steel throttle cable is now prepared for installation.
Solder the provided 2-56 solder link to one end of the cable
