32.Cut the control horn as photo shown.
33. Carefully cut a hole with hobby knife at the tail as the
elevator pushrod exit.
34.Use control horn as template and drill 5/64'' holes
with the control horn in line with the hinge line of
elevator and right at the pushrod exit.
35. Mount the control horn with 2X12mm screws. Insert
the elevator pushrod with clevis threaded on. Cut a
small piece of silicone and slide it onto the clevis. Then,
snap the clevis on the outmost hole of control horn.

36. Mount three servos on the servo tray which is
already installed in your fuselage. Note their orientation
in the photo. Follow your radio's instruction manual and
make sure you use the grommets, eyelets, and screws
furnished with your radio. Drill 1/16'' pilot holes for the
mounting screws before insertion.
37.Now it is time to hook the servos up to the control
surface. Install the pushrod connector onto the
outermost hole in the rudder servo arm as shown. To do
so, remove the servo arm from the servo place the
pushrod connector so the threaded portion exits the
bottom of the servo arms. Secure in place using a 2mm
washer and nut.
38.
Do the same procedure on throttle servo arm.
Ensure that the hole for the pushrod wire is parallel to
the length of the fuselage. Align the pushrod tube with
the servo. The pushrod tube should not extend all the
way to the servo as this would cause the pushrod to
bind during operation. To shorten the pushrod tube,
remove any excess length with a sharp hobby knife
accordingly. Insert the pushrod wire through the
pushrod connector. Secure in place using a 3mm set
screw. Carefully adjust the control throws as page 13
and 14 shown.

39.Hookup to the ailerons is via a nylon horn that is
threaded onto the torque rod that is already installed in
the wing. Screw the horn down until there is about 1/16''
of threads exposed above the horn. Use threaded rods
with clevises on the end for the linkage. Bend a "Z" bend
on the servo end of the rod at the proper length so you
have neutral aileron when the servo is centered.
40.Using the switch cover as a template, cut an opening
in the side of the fuselage to mount the switch in. It
should be on the left side of the fuselage. Drill two 1/16''
holes for the switch mounting screws and install the
switch.
There are 1/4'' holes in both fuselage sides in front of
the behind the wing opening for the wing hold-down
dowels. Cut the covering away from these holes and
install the two wing hold down dowels in these holes.
41.Wrap your receiver and battery with packing foam
which is available at local hobby shop. Install the
receiver and battery in the front of the servo tray.
Receiver is near the servo tray and battery is far from
the servo tray as shown.
Drill a 1/16'' hole through the fuselage side, about one
inch behind the switch mount. From the inside out,
thread the receiver antenna through this hole. You may
want to tie a knot in the antenna 3'' or 4'' from the
receiver to act as a strain relief. Attach the end of the
antenna to the top of the vertical fin with a small #10
rubber band and a T-pin. Maintain only a slight amount
of tension on the antenna wire.
CONTROL THROWS
42.Correctly install the prop in front of the spinner
backplate using the engine prop washer and prop nut.
Note that the spinner backplate has two little posts that
must be rotated up against the prop blade before the
spinner will fit on. Rotate the prop counter clockwise
until it is vertical when it is against the engine's
compression stroke. Securely tighten the prop nut using
a prop wrench or correctly fitting wrench. It is not a good
idea to use pliers when tightening the prop nut! Attach
the spinner to the spinner backplate using the two
3x12mm self tapping screws provided.
CONTROL THROWS
Make sure the direction of servo moves correctly. If not
switch the reversing switch on the transmitter. If the
control surface does not move far enough, either move
the pushrod out farther on the servo horn or move the
clevis in farther on the control horn.
If the control
surface moves too much, either move the pushrod in on
the servo horn or move the clevis out farther on the
control horn.
Adjust the control throws as following
suggested.
