Step 3
Install the recommended servo hardware (grommets and
eyelets) supplied with the servo. Temporarily install a long
half servo arm (JRPA212) onto the servo and position
the servo onto the hatch so the servo arm is centered in
the notch. Once satisfied, mark the location for the servo
mounting blocks using a felt-tipped pen.
Note
: Check to make sure your servo does
not hang off one end of the servo hatch.
If so, reposition the servo. Having the
servo fully on the hatch is more important
than having the servo arm centered.
Step 4
Locate two 3/8 x 3/4 x 3/4-inch (9.5 x 19 x 19mm) servo
mounting blocks. Use 12-minute epoxy to glue the blocks
to the hatch. Let the epoxy fully cure before proceeding to
the next step.
Step 5
Place the flap servo between the mounting blocks and use
a felt-tipped pen to mark the location of the four servo
mounting screws. Note that the servo must not touch the
hatch in order to isolate engine vibration.
Note
: Before mounting the flap servo, make
sure the servo arm is installed correctly on
the servo. This is done by moving the servo
from each end point to determine the center
position of the servo. With the radio off,
secure the servo arm in the center position.
Check the operation of the servo to determine
if the two end positions of the arm are equal.
If not, reposition the arm as necessary.
Step 6
Remove the servo and use a 1/16-inch (1.5mm) drill bit to
pre-drill the holes for the servo mounting screws marked
in the previous step. Use the screws supplied with the
servo to mount it to the servo mounting blocks.
