Step 4
Use a #1 Phillips screwdriver to remove the servo horn from
the servo. Position the servo on the cover. Use the lines for
aligning the servo on the cover.
Step 5
Use a pencil to mark the position for the second servo
mounting block on the servo cover.
Hint
: Use a 1/32-inch (.5mm) spacer between the
servo and flap servo cover before marking for the servo
mounting screws to set the correct spacing.
Step 6
Use medium grit sandpaper to scuff the ends of two servo
mounting blocks as shown.
Sand this end
Step 7
Mix a small amount of 30-minute epoxy. Apply the epoxy
to the end of the blocks that were sanded in the previous
step. Position the blocks on the servo cover using the marks
made previously. Use small clamps to hold the blocks tightly
against the servo cover until the epoxy fully cures.
Step 8
Use the radio system to center the flap servo. If your radio
uses a three-position switch, set the switch in the center
position. If you have a two-position switch, setting the
throws to 0% for both positions will also center the flap
servo. Install a servo horn on the flap servo that has a hole
13/32-inch (10mm) from the center of the horn. Install the
horn on the flap servo as shown.
Hint
: Most servos have an odd number of splines. If
the horn is not aligned correctly as shown, you can
rotate it 180 degrees to bring it into alignment.
Step 9
Use side cutters to remove any arms that will not be used
from the servo horn. Trim the horn down leaving only the
hole that was 13/32-inch (10mm) from the center of the
horn.
