Section 5-Wing Anti-Rotation Pins and Servo Installation

Required Tools and Adhesive
• 5-15 minute epoxy
• Ruler
• Coarse sandpaper
• Acetone/Alcohol swab
• Thin C/A
• Micro balloons
• (2) 24" servo extensions
• (2) 1.5" aluminum servo arms
• Long rod such as 48" Dubro
rod.
Step 1
Prepare the aluminum anti-rotation
pins by using coarse sandpaper and
rough up the end of the pin where it
will be inserted in the second rib in
the wing. Now clean the pins with
acetone or alcohol to remove any
possible grease or dirt.
Step 2
Install the anti-rotation pins using the
following dimensions. The front pin
should measure 10.5mm. Note: the
picture showing the measurement
with the ruler may not look like
exactly 10.5 however 10.5 mm is the
correct distance from the root rib to
the center hole for the keeper clip at
the end of the anti-rotation pin. Also
this ruler starts at zero, yours may
not start at zero. The rear pin should
measure 8 mm from the root rib to
the center of the hole. The front and
rear pin should have the hole in a
vertical position.
