Mount The Tail Gear; Mount The Engine Or Electric Motor - GREAT PLANES EXTRA 330S Instruction Manual

connector. If using a Futaba dual servo connector, the heat-
shrink tubing will have to be stretched to fi t over the connector
by slipping it over long nose pliers and holding it open to
stretch the heat-shrink tubing. Fit the heat-shrink tubing over
the connector, and then shrink the tubing.

Mount the Tail Gear

Refer to this photo and the sketch while mounting the
tail gear.
❏
1. Cut the covering from the hole in the bottom of the
fuselage for the nylon tail gear bearing. Roughen the
bearing with medium-grit sandpaper. Then, use medium CA
to securely glue the tail gear bearing into position. Use care
not to get any glue inside the bearing.
❏
2. Mount the aluminum collar to the tail gear wire with the
set screw and a drop of threadlocker applied to the threads.
Use the hex wrench included with the tail gear (or your own
1/16" [1.6mm] hex wrench) to tighten the set screw.
❏
3. Drill 1/16" [1.6mm] holes into the bottom of the fuselage
for the bracket mounting screws. Temporarily mount the
bracket and the tail gear with #2 x 1/2" [13mm] screws.
Remove the screws, set the bracket aside, add a drop or two
of thin CA to each screw hole, and allow to harden. Then,
remount the bracket with the screws.
❏
4. Drill a 5/32" [4mm] hole through the middle of the bottom
of the rudder 4" [100mm] from the leading edge. Fit the tiller
spring into the steering post, insert the post onto the hole in
the rudder, and permanently glue in the post with thin CA.
Note: If you prefer working on the model with it resting on
its landing gear rather than sitting in your building stand, you
may go ahead and mount the main landing gear (with or
without the wheels for now) at this time. If you want to mount
the landing gear, use six 6-32 x 3/4" [19mm] SHCS, #6 lock
washers, #6 fl at washers and a drop of threadlocker on the
threads. If you want to mount the wheels too skip ahead to
"Mount the Landing Gear" on page 32.

Mount the Engine or Electric Motor

❏
1. Turn to the back cover page and cut out the mounting
template for the type of power system you will be using–one
template is for the Fuji-Imvac BT-43EI-2 gas engine and
the other is for both the included Great Planes 1.20 to 1.80
adjustable engine mount for glow engines and the ElectriFly
Brushless Motor Mount for extra large motors (GPMG1265
– not included).
❏
2. Tape the template to the fi rewall with the cross marks
on the template aligned with the cross marks on the fi rewall.
Use a piece of wire sharpened on the end or a T-pin to mark
the cross marks for the bolt holes in the template onto the
fi rewall. Note: If mounting a gas engine different than the
Fuji-Imvac BT-43EI-2, use the mounting template that came
with your engine or make your own template, or center the
engine on the cross marks and use the mounting holes in
the engine to mark the fi rewall. Note: If using the O.S. 1.60
FX, also mark the location for the throttle pushrod.
❏
3. Remove the template. Drill 1/16" [1.6mm] pilot holes at
all the marks. If mounting the Fuji-Imvac BT-43EI-2 engine,
enlarge the pilot holes with a 1/4" [6.4mm] drill for 10-32 or
10-24 blind nuts. If using the included 1.20 to 1.80 adjustable
engine mount for glow engines or the ElectriFly motor mount,
enlarge the pilot holes with a 3/16" [4.8mm] drill for the
included 8-32 blind nuts. If using the O.S. 1.60, also enlarge
the pilot hole for the throttle with a 3/16" [4.8mm] drill.
