Parts Needed
• Wing assembly
• Flap control wire (threaded on both ends) (2)
• 4-40 clevises (4)
• 4-40 locknuts (4)
• Reversed Y-Harness (EXRA325) or
• MatchBox™ (JRPA900)
Tools and Adhesives Needed
• Adjustable wrench
• Pliers
Note
: The flap servos can be actuated through
one channel of your receiver by utilizing a
reversed Y-Harness (EXRA325). If you have a
computer radio with spare channels, you may wish
to use a programmable mix to set up the flap
servos. Another option is to use a MatchBox
(JRPA900) from JR. With this option, you only use
one channel on your receiver but retain all the
flexibility of using a programmable mix such as
setting servo direction, center and end-points.
Step 1
Remove the flap servo and hatch assembly. Using your radio,
adjust the flap servo arm to be approximately 45 degrees when
the flap switch is in the up position. Make sure both flap servos
are adjusted the same.
Step 2
Locate the flap control wires (2) 4-40 locknuts and clevises (4).
Thread a locknut and clevis onto each end of the flap control
wires a minimum of 12 turns.
Step 3
Attach one end of the flap control wire to the flap horn as
shown. Ensure that the clevis and locknut pass through
the opening in the trailing edge without binding. If necessary,
enlarge the opening in the trailing edge using a sharp
hobby knife.
