When centering the flap servo, begin by setting
the throws at the transmitter to 0% for both
the up and down flap positions. This is done
for both 2- and 3-position flap switches.
1. Prepare the flap servo by installing the rubber
grommets and brass eyelets as shown in the radio
or servo instructions. Center the flap servo using the
radio system. Use side cutters to remove any arms
from the horn that may interfere with the operation
of the servo.
The flap linkage will be connected to the hole in
the servo horn 1/2-inch (13mm) from the center
of the arm as illustrated in the photo above.
2. Repeat step 1 to prepare a second flap servo.
Note the servos will be identical.
3. Use a pencil to draw two lines on the cover. The
first line is along the bottom of the cover, 3/32-inch
(2.5mm) from the edge. The second line is 7/8-
inch (22mm) from the side of the cover as shown.
This will center the servo horn in the slot when
using the recommended servos.
4. Sand the 10mm x 7mm end of the block using
medium grit sandpaper. This will be the end glued
to the plate in the following step.
