Q 3. Install the servos using the hardware included
with your radio system. Use the plan as a guide
to position the servos laterally in the fuselage.
Q4. Install the receiver, battery and switch. Use
foam to cushion the receiver and battery.
Q 1. Hold the nylon control horns on the
elevator and rudder in the positions shown on
the plan and mark the mounting hole locations.
Drill 3/32" diameter holes at these locations.
Q 2. Harden the balsa in the area of the
control horns (on both sides of the control
surfaces) by poking several holes with a pin,
then apply thin CA glue. Sand smooth.
Ql 3. Mount the horns with 2-56 screws and the
nylon backing plates which were attached to
the horns.
4. Use a hobby knife to sharpen one end of
a piece of 3/16" (outside diameter) brass tubing,
then use this tubing to cut the pushrod exit holes
(you may use a 3/16" drill bit, but the brass tube
method gives a much neater cut). Determine
the location of these holes from the plan.
Q Q 5. Insert the plastic pushrod tubes through
the holes you just cut. Route the pushrod tubes
according to the plan. Keep the tubes as
straight as possible. Glue the tubes to the fuse
sides at the rear exit points using thin CA glue.
Q Q 6. Cut off the tubes at the exit points and
sand them flush with the fuse sides using a
sanding block. Use balsa filler to fill any gaps
between the tubes and fuse sides.
Q Q 7. Thread one of the 2-56 x 1 threaded
rods into one of the nylon pushrods.Thread a
nylon clevis 14 turns onto the threaded rod.
Slide the pushrod into the tube from the rear of
the fuselage. Attach the clevis onto the appropriate
control horn.
