STABILIZER AND ELEVATOR INSTALLATION
1.
Use a hobby knife with a #11 blade to remove the
covering for the stabilizer screws.
2.
Slide the stabilizer tube into the socket in the stabilizer.
The tube will slide in easily, so don’t force it any more
than it will easily slide.
3.
Slide the stabilizer tube into the fuselage.
4.
Slide a #8 lock washer, the #8 washer on a 8-32 x 3/4-
inch socket head cap screw. Prepare all four screws at
this time.
5.
Slide the stabilizer tight against the fuselage. Secure it
using two of the screws prepared in the previous step.
Use a 3/32-inch hex wrench to tighten the screws.
Repeat the previous steps to
install the remaining stabilizer.
6.
Prepare the clevis on the elevator pushrod by sliding a
clevis retainer into position, then threading the nut and
clevis on the pushrod. Slide the pushrod into the tube in
the fuselage and attach the clevis to the elevator control
horn.
7.
Slide a clevis retainer on the clevis. Thread a nut and
clevis on the elevator pushrod. With the elevator servo
centered, adjust the clevises so the elevator is centered.
Apply a drop of threadlock on the pushrod, then tighten
the nut against the clevis. Slide the retainer over the
forks of the clevis to complete the elevator pushrod
installation. Install the remaining elevator pushrod at
this time. The clevis will attach to the arm 13/16 inches
(21mm) from the center of the arm.
TAIL WHEEL INSTALLATION
1.
Use a felt-tipped pen to mark the rudder 11/16 inches
(17mm) behind the hinge line. Use a drill and 3/32-inch
(2.5mm) drill bit to drill a hole at the mark, centered from
the sides of the rudder.
2.
Use the rear hole in the tiller arm and a #6 x 3/4-inch
sheet metal screw to temporarily attach it to the rudder.
Use a #2 Phillips screwdriver to tighten the screw. Align
the bracket centered on the bottom of the rudder. Use a
drill and 3/32-inch (2.5mm) drill bit to drill the remaining
mounting screw hole at the front of the tiller arm.
3.
Remove the bracket and screw. Thread a screw in the
remaining hole using a #2 Phillips screwdriver, then
remove the screw. Harden the wood in the holes by
applying a few drops of thin CA in each hole. Once the
CA fully cures, attach the bracket to the bottom of the
rudder using two #6 x 3/4-inch sheet metal screws and
a #2 Phillips screwdriver.
