11. Temporarily attach the elevators and rudder to check
their fit and operation. Note that you must cut a notch in the
rudder leading edge to clear the 1/8" wire elevator joiner.
12. Finally, glue the 5/16" balsa dorsal fin in place on
the turtle deck. The dorsal fin, like the fin, must also line up
with the fuselage centerline. Sand the dorsal fin to a rounded
shape, and blend it to the fin with balsa filler.
scrap, and glue them in place. (See the side view of the
aileron servo installation on the plan).
4. Mount the aileron servo using the screws provided
with your radio.
5. Screw the nylon aileron clevises approximately 2/3
of the way onto the threaded end of the two 12" steel wire
pushrods.
Nylon Aileron
Clevis & Conn.
6. Screw the nylon aileron clevis connectors onto the
INSTALL SERVOS, HORNS AND
PUSHRODS aileron torque rods.
7. Attach the clevises to the clevis connectors, then,
1. Study the plans to determine the location of the
aileron servo cutout. Mark the location on the top of the
wing and cutan opening in the fiberglass and sheeting slightly
larger than your servo. CAUTION: Do not cut into the wing
spars or shear webs!
with the ailerons in the neutral position, mark the pushrod
wires where they cross the holes in the servo arm. Remove the
pushrods and make a "Z-bend" in the rods at that point,
using a "Z-bend pliers" or a standard pliers.
8. Remove the servo wheel from the servo and work
2. Remove a sufficient portion of the W-l ribs to fit
your servo, leaving "shelves" on which to glue the 1/8" ply
rails. (See the plan to determine the depth). NOTE: A
Dremel Moto Tool with a 1/8" router bit is excellent for this,
but it may also be done with an Xacto knife and a long-nose
pliers.
3. Make two servo rails from the 1/8" ply die-cutting
the Z-bends into the wheel (NOTE: You may have to enlarge
the servo wheel holes with a 5/64" diameter drill bit). Replace
the servo wheel and check the operation of the ailerons. (See
page 35 for the recommended amount of aileron movement).
REMEMBER: Plan your servo installation carefully, as
your setup may differ from the plans and photos, depending
on which engine you use, and whether you are building a trike
or taildragger.
