Section 3: Installing The Aileron Servos - Hangar 9 P-51 Mustang ARF Instruction Manual

Section 3
Installing the Aileron Servos
Parts Needed
Wing assembly
Aileron servos w/mounting hardware (2)
Servo hatch screws (#2 x 3/8") (8)
18" servo wire extension (JRPA099) (2)
Large Servo Arm (JRPA212) (1 pkg.)
Tools and Adhesives Needed
Phillips screwdriver
Thin CA
Thick CA
Step 1. Locate the aileron hatch on the underside of the wing
panel. Using a sharp hobby knife carefully cut along the edges
of the hatch, then remove the hatch from the wing panel. Also
cut out the slot for the servo arm at this time. Locate the servo
lead extension exit holes on the top of the inboard portion of the
wing. Using a sharp hobby knife carefully cut away the covering
over the hole.
Note: The aileron servo will be mounted to the hatch.
Step 2. Install the recommended servo hardware (grommets
and eyelets) supplied with your radio system onto the aileron
servo. Temporarily install a long half servo arm (JRPA212) onto
the servo and test fit the servo to the hatch. The servo output
shaft and control arm should be centered in the slot of the hatch.
Once satisfied, mark the location for the servo mounting blocks.

Step 3. Locate the servo mounting blocks. Using a few drops
of thin CA, tack glue them in place on the marks made in the
previous step. Check the fit of the servo between the mounting
blocks. When satisfied with the fit, permanently glue the
mounting blocks in place by first wicking thin CA between the
mounting blocks and the hatch, and then using thick CA create
a fillet around the base. Let the CA completely dry before
proceeding to the next step.
