Gas Engine - GREAT PLANES Giant Super Sportster Instruction Manual

Refer to the following two photos
while hooking up the throttle.
❏
8. If necessary, remove the engine. Drill a 3/16" [4.8 mm]
hole through the firewall where you made the mark for the
throttle pushrod.
❏
9. Cut the 3/16" x 24" [4.8 x 610 mm] gray pushrod tube
to the correct length to be used for the throttle pushrod guide
tube, and then roughen the outside with coarse sandpaper
so glue will adhere. Guide the pushrod tube through the
firewall and the slotted holes on either side of the former that
holds the wing dowels.
Note: A plywood pushrod guide tube
mount is supplied with this kit. If the
throttle does not align with one of the
slotted holes in the former, you could
position the pushrod tube outside the
slots and use the mount to secure the
throttle pushrod tube. Just slip the mount
over the tube and glue it to the former.
❏
10. Securely glue the plywood servo tray into position so
that the cutout for the throttle servo will be on the same side
as the throttle pushrod. Drop the throttle servo into the tray.
❏
11. Hook up the throttle using the hardware shown.
Mount the servo to the tray with the screws that came with
the servo. Remove the servo and harden the holes with a
few drops of thin CA, and then remount the servo. Glue in
the throttle pushrod guide tube with CA.
If mounting a gas engine other than the Fuji BT-32, use
these instructions as a guide for mounting your engine
in a similar manner.
❏
1. Drill 1/16" [1.6 mm] pilot holes through the firewall at
the four marks for the Fuji Engine. Enlarge the holes with a
1/8" [3.2 mm] drill, followed by a 1/4" [6.4 mm] drill. Note:
The Fuji engine mounting holes are centered over the cross
marks on the firewall. If using a different engine, be sure to
center the engine mount (or the engine) on the cross marks.
❏
2. Apply a few dabs of epoxy to the front of the four 5mm
blind nuts. Use a 5 x 60mm socket-head cap screw (SHCS)
with a few 5mm washers and one of the aluminum engine
spacers to draw each blind nut into the back of the firewall.
Hint: If you have difficulty getting the blind nuts started in the
holes, remove one of the aileron pushrods and use it to pull
the blind nuts through with a 4-40 nut (as shown for the glow
engine mounting in Step 2 on page 14). Once the blind nuts
are partially stuck, use the 5mm screw, washers and spacer
to draw it the rest of the way in.

washers and flat washers and the engine spacers.
