Required Tools and Adhesives
• Drill
• Long servo arm (5)
• Drill bit: 1/16-inch (1.5mm), 5/64-inch (2mm)
• 18-inch (458mm) servo extension (3)
• Painters tape
Step 1
Secure an 18-inch (458mm) servo extension to the
rudder servo lead. Use string or a commercially available
connector to make sure the extension will not unplug from
the servo lead.
Hint
: Use painters tape to secure the
control surfaces and keep them in
neutral while installing the linkages.
Step 2
Use the hardware provided with the servo to secure it in
the fuselage as shown. You will want to drill 1/16-inch
(1.5mm) holes for the servo screws and harden them with
thin CA to help in preventing the screws from pulling out.
Attach a large servo arm to the servo.
Step 3
Enlarge the outer hole of the servo arm using a 5/64-inch
(2mm) drill bit. Attach the 10
