D 7. "Lock" the servo tray in place by gluing a few
scraps of 1/8" ply (from the die- cutting scrap) to the
fuse side and the top of the servo tray using thick
CA as shown here.
D 8. Put the servos into the tray and screw them
down with the screws provided with your radio.
Tighten the screws "finger tight , not wrench tight".
D 9. Make a single servo mount as described below,
for the aileron servo. This is only required for Wing
B. If you built Wing A, skip to the next section.
From 1/8" plywood die-cutting scraps, cut one
piece 1-1/8" wide x 2-7/16" long. Also cut two pieces
3/8" wide x 1-3/16" long, with the wood grain running
the long way. From the 3/8" x 5/8" x 2-1/2" balsa pro-
vided, cut two triangular servo rail braces. Use the
pattern shown here:
Glue the above five parts together to make the
single servo mount. Study the plan to see how they
go together.
D 10. While holding the servo in place on the rails,
mark the location of the four mounting holes through
the brass eyelets onto the plywood. Drill 1/16" holes
at these marks.
D 11. Attach a large servo wheel to your 4th servo.
D 12. Determine from the plan (See the "Bottom of
Wing" detail) exactly where this aileron servo mount
should be located. Lay the mount in place on the
bottom of the wing and using a felt-tip marker, draw
a dark line around the base of the servo mount. DO
NOT GLUE THE SERVO MOUNT TO THE WING
UNTIL AFTER COVERING.
D 13. Screw the aileron servo to the mount using
the screws provided with your radio.
INSTALL NYLON CONTROL HORNS
D 1. Find the set of two nylon control horns and
cut them apart with an X-acto knife. Also find the
four 2-56 screws that are 5/8" long.
2-56 x 5/8" S C R E W
D 2. Remove the rudder and elevator from the fin
and stab. Remove the hinges.
D 3. Lay the rudder on the fuselage plan side view
and determine where the nylon control horn should
be located. Holding one of the nylon horns in place
on the left side of the rudder, use a pencil to mark
through the holes in the horn.
D 4. Drill 3/32" holes through the rudder at the
marks you just drew.
D 5. Repeat steps 3 and 4, locating and drilling
holes in the elevator. Note: When marking the lo-
cations for drilling, you must hold the nylon horn
on the BOTTOM of the elevator!
