Owner manual

6. Trim one end of three large Robart Hinge Points
so they will fit into the flap. Test fit the flap to the wing
with the hinges. Move the flap up and down to align
the hinges and see how the flap fits. Make any
adjustments needed for smooth operation.
7. Hinge the other flap the same way.
MOUNT THE FLAP AND AILERON SERVOS
1. Cut four (or eight if building working flaps) 7/8"
[22.2mm] servo mounts from the 3/8" x 3/8" x 24"
[9.5 x 9.5 x 610mm] basswood stick. (Save the
remainder of the stick for mounting the fuselage.)
Glue one servo mount to each of the die-cut 1/16"
[1.6mm] plywood servo mount supports.
Mount the aileron servos first…
Refer to this photo to mount the servos to the hatches.
2. Mount the aileron servos to the servo mounts by
drilling 1/16" [1.6mm] holes into the servo mounts and
using the servo screws that came with the servos. Make
sure the second servo is mounted in a “mirror image” of
the other for the opposite side of the wing.
3.Temporarily remove the screws, add a few drops
of thin CA to the holes, allow to harden, then remount
the servos.
4. Cut off the unused servo arms. Use 30-minute
epoxy to securely glue the servo mounts to the
hatches. Make sure the servo arms are centered in
the openings.
Futaba servo arms
Have you ever noticed the small, molded-in
numbers on the Futaba servo arms? Each
number represents the number of degrees that
the arm is offset from 90-degrees. Due to mass-
production variances, not all servos are exactly
the same. Before cutting off the unused servo
arms, determine which arm is the correct one to
keep for that servo. To do this, connect the servo
to the desired channel in the receiver. Turn on the
transmitter and receiver, then center the trim lever.
Position the arm on the servo until you find one
that is 90-degrees, then cut off the others. Now
your servo arm will be centered when your trim is
centered—of course, this procedure could be
done when actually setting up the radio after the
model has been finished.
