3. Install the flap on the wing and check its
fit and range of motion. Make any required
adjustments until the flap moves freely through its
range of motion (remember the flap is not required
to raise above neutral).
❏
4. Mark a centerline on the LE of the aileron.
Shape the LE of the ailerons to the “V” shape as
shown below and on the cross-section on the
wing plan.
❏
5. Use the same method that was used on the
aileron to install the elevator and rudder.
INSTALL THE AILERON AND
FLAP SERVOS
❏
1. Trace the outline of the die-cut 1/16" plywood
aileron and flap servo bay covers accurately onto
the wing skin over their proper location. Carefully
cut out the bays and fit the covers into place.
❏
2. Cut hatch guides from leftover 1/4" x 1/4"
balsa stringers. Use thin CA to glue the guides
between the hatch blocks, flush with the bottom of
the wing skin.
NOTE: Unless you have a reverse throw servo,
you will need to mount the flap servos in an
asymmetrical manner as shown on the wing plan
to have them both move in the same direction.
❏
3. Tape the hatches in place and drill 1/16" pilot
holes at the punch marks on the hatches and into
the hatch blocks. Remove the hatches and enlarge
the holes in them to 3/32". Countersink the holes
in the hatches to accept the #2 x 3/8" flat head
screws. Secure the hatches to the hatch blocks
with the #2 x 3/8" flat head screws.
❏
4. Remove the servo hatches from the wing.
Apply a drop of thin CA to each hole in the hatch
blocks to harden the threads.
B. Using the “bevel to” lines and the centerline
as a guide, make the “V” on the LE of the aileron
with a razor plane or your bar sander.
A. Place the LE of one of the ailerons on your
work surface and use a pen to mark a “bevel to”
line on both sides about 3/16" high.
NOTE: Use a piece of card stock to adjust the
height of the pen or aileron as needed.
