Section 3: Aileron/Flap Servo Installation
13
Required Parts
• Assembled wing
• 12" Servo extension (2)
(2 additional 24" for quad-flap configuration
wing)
• Standard size servos with mounting hardware (2)
(4 for quad-flap configuration)
Note
: The flap servo must be reversed if using a
Y-harness for flaps.
Required Tools and Adhesives
• Hobby knife
• Needle-nose pliers
• Drill
• Drill Bit: 1/16"
• Masking tape
• Pencil
• String with weight on end
• Phillips screwdriver (medium)
Step 1
Locate the servo openings in the bottom of each of the
wing halves. Use a sharp hobby knife to trim away the
covering over the openings. If you’re building the
conventional wing, you will only cut out the openings
that are closest to the wing root for the aileron servos.
If you build the quad-flap wing, trim away the covering
on all four servo openings in the wing. Use care not to
cut away too much of the covering.
Step 2
Install the recommended servo hardware supplied with
your radio system onto your servos, (grommets and
eyelets). Install 12" servo extensions on the flap servo
lead and 24" extensions on the aileron servo leads.
Secure the connectors with either masking tape or a
commercial connector that prevents the servo lead
connections from becoming disconnected.
Hint
: It’s always a good idea to tape or secure
the servo connectors and servo extension
together to prevent the wires from becoming
unplugged inside the wing.
Step 3
Trial fit the servo into the servo opening. Depending upon
the type of servo installed, some trimming may be
required. Note that the servo is orientated so the servo
output shaft is closer to the trailing edge of the wing.
