2. At each hinge location drill a 3/16" hole
(depending on the type of hinges you are using)
centered on the TE of the wing and LE of the flap
and aileron. Use a sharp hobby knife to make a
V-notch in the LE of the flap as shown. This will
allow the hinge point pivot to be at the center of
the radius of the flap LE.
NOTE: The hinges are not glued in until after the
finish has been applied
❏
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.
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.
