c) The tailskid wheel pant halves are glued to each side of the
tailskid wire. Hold the pant halves in place with the tailskid wire
between them.
Pinch the halves hard to leave the wires'
impression on the inside faces of the pant halves. Use a hobby
knife to open up the impressions just a little, allowing the wire to
"nest" in place between the pant halves. The pant halves are now
glued in place, sandwiching the tailskid wire between them. Use
SIG thick CA or 5-minute epoxy for this step.

7) The rudder is now ready for hinging to the vertical fin with
two CA hinges. The procedure is exactly the same as those for
hinging elevators back in Step 3. Insert the two hinges into the
vertical fin, with their center slots aligned with the trailing edge of
the fin. Insert thin scrap wood or cardboard into these slots to keep
them centered and from being pushed further into the fin. Slide the
rudder onto the exposed hinge edges, up to the scrap
inserts. Remove one of the spacers, flex the rudder over to one
side and apply 3 or 4 drops of thin CA glue to the exposed center
of the hinge. Turn the fuselage over and apply another 3 or 4 drops
of glue to the other side of the hinge. Repeat this operation on the
remaining rudder hinge. Allow about 10 minutes before flexing the
hinges.
OPTIONAL LANDING GEAR FAIRINGS:
Included with your kit is a card sheet measuring 2-1/2" x 4-1/4".
This is the material used to make the optional landing gear
fairings. Use the patterns provided in this manual. First, remove
the wheel pants. Cut-out two landing gear fairings from the card
stock and bend them in two sharply at their leading edges. Mix a
small amount of 5-minute epoxy and spread it on the inside
surface of the fairing. Place the fairing onto the wire landing gear
legs and clamp or tape securely at the trailing edge. Align them
accurately with the fuselage and allow the glue to set.
Use light sandpaper (#400 or so) to lightly sand the trailing edges
smooth and sharp. The fairings can now be finished in either paint
or covered with Oracover® film. Remount the wheel pants.
MOTOR AND RADIO INSTALLATION:
❑
1) The motor and gearbox are now assembled. Install the
12-tooth 2.5:1 primary brass gear to the motor. Use threadlock
compound on the setscrew. Assemble the gearbox to the motor
using the two provided bolts, again using threadlock compound on
the bolt threads. Before tightening the bolts, position the gears
together with just the slightest amount of "play" or gear lash. Do
not assemble the gearbox to the motor with these two gears too
tightly meshed or too loose.

MODELER’S TIP: The overall look of the tailskid/wheel pant
assembly can be easily enhanced by filling in the exposed
"wheel" part of the wire with a small scrap piece of 1/32"
balsa. Use thin CA to glue the wood in place, sand the sides
smooth to the wire and paint with flat black paint. The finished
product will look just like a tail wheel!
