.
103. Hold the legs of the 3/16" main I.g. wires together and add the 1/8" bottom shock
strut wire between them. Rebend the wires slightly, if necessary, to get all of the
wires to line up properly. Cyanoacrylate adhesive can be used to hold the wires
together temporarily. When you have them aligned, bind them tightly together
with copper wire then solder securely. Use plenty of heat and soldering paste so
that the solder will flow completely around and through the bindings. Drape a
cloth over the center section to protect it from dripping solder or paste.
104.
Remove the wire gear from the wing, then bind and solder the, 1/8" dia. top
shock strut wire in place. After all of the joints are cool, file and sand them to
smooth out any prominent bulges in the bindings. Clean all joints with dope
thinner or other suitable solvent.
105.
Cut a 1" long piece of scrap 1/16" dia. music wire (or similar) from leftover pieces you undoubtably have in your workshop.
Form it into a shallow "V", then bind and solder it to the top shock strut wire. This serves as a hook for wrapping rubber
bands around both shock strut wires to act as a shock absorber.
106.
Refit the landing gear to the wing. Position the four large nylon landing gear
straps over the wires, as far outboard on each side as practical. (Positioning the
straps this way will help to prevent the gear from shifting side-to-side during
rough landings.) Mark the hole locations for the straps, then pilot drill the landing
gear mounts and thread in the screws.
107.
a. A single sheet of 3/16"x4"x12" balsa is provided for fairing in the sides of the landing gear. Cut out pieces to fit
between the 3/16" wires, noting the grain direction shown on the plans. Epoxy the fairings in place and allow to dry.
b. Heavy-weight fiberglass cloth is provided for reinforcing the landing gear and the fairings. Cover one side at a time
using slow-drying epoxy to apply. Lap the cloth past the edges of the wood, completely around the 3/16" wires.
When dry, sand smooth.
COMPLETING THE MODEL
Wheel Pants
The directions given below are for a single wheel pant. Of course, you must
make two wheel pant assemblies, a left and a right.
108.
a. Clean and sand the inside surface of the pant where the diecut 1/16" plywood mounting plate will attach. Epoxy the
plate in place as shown on the plans (Plate 4).
b. Carefully locate and mark the position of the axle on the wheel pant using the plans as a guide. Drill through the
pant and mounting plate with a 3/16" drill bit.
c. Install a 6-32 x 3/8" socket-head set screw into one of the molded nylon wheel pant mounts. Temporarily hold it on
the outside of the pant and mark the location of the two outer holes. Drill through the pant at the marks with a 3/32"
drill bit. Permanently fasten the wheel pant mount to the inside of the wheel pant with two #4 x 3/8" sheet metal
screws.
d. You must grind or file a shallow flat spot on the wire landing gear where the wheel pant mount's set screw makes
contact. The position of this flat spot will also determine the position of the wheel pant. The flat spot may have to be
slightly re-ground several times before the wheel pant assumes the correct angle. The centerline of the pant should
generally be parallel with the fuselage top longeron, and both pants should be parallel to each other.
