INSTALL SERVOS AND PUSHROD GUIDE TUBES
PARTS NEEDED:
D (2) US1 0F09 1/4" x 1/2" x 4-3/8" Ply Servo Rails
D (4) PLTB002 36" Plastic Outer Pushrod Guide Tube
D (1) NYLON69 Nylon Nosegear Steering Arm
D (1) SCRW007 6-32 x 1/4" Socket Head Cap Screw
D (2) WIRES17 34" Steel Pushrod Wires
NOTE: Although you may choose to wait until later,
this is the best time to install the pushrod guides,
because the fuselage is wide open and it is very easy
to work inside.
IMPORTANT: Before proceeding, plan your servo
and pushrod installation. Especially note which side
of the fuselage the throttle pushrod and nose gear
pushrod (if any) will be located. Remember that the
throttle arms of 2-cycle and some 4-cycle engines are
on opposite sides. It will be helpful to actually sketch
your pushrod locations on the plans with a pencil. It is
desirable for the throttle pushrod (and the nosegear
steering pushrod) to run along the sides of the
fuselage. It is also desirable (but not essential) for the
rudder and elevator pushrods to cross inside the
fuselage, to avoid any sharp bends.
D 1. Set the fuselage upside down on blocks at least
1/2-inch high.
D 2. Trim the 1/4" x 1/2" x 4-3/8" ply servo rails to fit
between the fuse side doublers in the locations shown
on the plan. Temporarily mount your servos to the
rails, and then glue the rails to the fuse side doublers.
(Note that the surface of the rails is even with the edge
of the lightening holes in the fuse side doublers).
Securely lock the rails in place by gluing scraps of
plywood on the top and bottom of the rails.
3. Sand the outer surface of the pushrod guide
tubes with 100-grit sandpaper, providing a surface to
which the glue will adhere.
D 4. Use an X-acto 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 plans. You may chuck this brass
tube in an electric drill to aid in getting through the ply
doublers and F-6.
D 5. Insert the plastic pushrod tubes through the
holes you just cut and through formers P-5 and F-4.
D 6. Route the pushrod tubes according to your
radio installation plan. Temporarily insert the 34"
pushrod wires into the tubes and hold them in the
correct position (with tape) at the servo end. Keep
the tubes as straight as possible. Glue the tube to
the fuse sides at the rear exit points using thin CA
glue. Use scraps of 1/8" balsa to anchor the tubes to
F-5. Do not anchor the tubes to F-4 at this time,
to allow for slight adjustment of their positions later.
