Great Planes Giles G-202 46 Kit - GPMA0238 - Manual (Page 32)

❏
5. Use the Great Planes Dead Center ™ Engine Mount
Hole Locator to mark the locations of the bolt holes.
Remove the engine from the mount and drill four 7/64"
holes. Tap the engine mount with a 6-32 tap for the 6/32
x 3/4" socket head engine mounting bolts.
❏
1. Select the 11-3/4" grey outer pushrod guide tube for
the throttle. Use coarse sandpaper to roughen the outside
of the tube so glue will stick. Slide it through its hole in the
firewall and use medium CA to glue it into the firewall. Cut
the pushrod outer tube flush with the outside of the firewall.
Position the die-cut 1/8" ply throttle pushrod retainer in
place against F-3, using a ruler to ensure that it does not
protrude into the wing saddle. Glue in place with thin CA.
❏
2. Mount the throttle servo as shown on the plans in the
right side of the servo tray.
❏
3. Install a nylon clevis to the 17-1/2" throttle pushrod
wire. Slide the throttle pushrod through the pushrod tube
with the clevis on the servo end. Without attaching the
clevis to the servo, bend the pushrod as needed to make
the pushrod move smoothly and the clevis properly reach
the servo arm.
❏
4. Bend and/or cut the engine end of the throttle
pushrod as needed to fit the engine installation, using the
drawing on the fuselage plan as a guide. Make adjustments
to the bends in the wire so the pushrod aligns with the
carburetor arm on the engine, then temporarily connect the
pushrod to the carb arm with whatever connection type you
have selected for the throttle. (We recommend a Great
Planes Screw-Lock Pushrod Connector, not included, for
the throttle connection for ease of use and adjustment.)
Temporarily mount the muffler and make sure the throttle
pushrod will not interfere with the muffler. Make
adjustments to the bends in the wire if necessary. Note:
Because of the close tolerances between the servos and
the wing, do not use Screw-Lock Pushrod Connectors on
the pushrods at the servo.
❏
5. Thread a nylon clevis onto the 36" pushrod wire
(threaded on one end) for the rudder pushrod. Slide the
pushrod wire through the rudder pushrod guide tube, which
is the lower guide tube on the left side of the fuselage.
Remove the backing plate from a nylon control horn and
connect the horn to the clevis in the outer hole. Fit the
rudder to the fin, using the hinges to hold them in place.
DO NOT GLUE THE HINGES IN PLACE.
At this point, you MUST choose your rudder servo location.
If you are installing anything but the lightest of engines in
the recommended range, we recommend the aft rudder
location to assist in balancing the model, as well as
providing very short, tight rudder linkages for optimal
performance. If you are using the forward rudder servo
location, complete steps 5 through 8. If you are using the
optional rear-mounted servo location, mount and hook up
your rudder servo, using the plans as a guideline, and
remembering that you will need to move the control horn
and cut the pushrod to the appropriate length.
