 6. Attach the linkage to the servo arm at the 1 inch
hole. If using aluminum JR arms, use the second hole from
center outward. Use threadlock on all the screws except for
the two setscrews of the arm.
 7. To adjust the length of linkages, servos need to be
powered and at center. The arm should be mounted parallel
to the aileron hinge line; small adjustments can be made
using sub-trim. Adjust the length of linkage so the aileron is
centered and servo arm is parallel to the hinge line.
 8. Mount the inboard servo following the same method
as outboard but no extension is required.
 9. Mount the MatchBox™ in the wing root using sticky
back hook and loop. Before applying the hook and loop
to the MatchBox, apply masking tape to the back of the
MatchBox so it can easily be removed when need be.
Matchbox Programming Hints
The pointers below can help make matching servos easier.
This is not to take the place of the MatchBox instruction
manual.
 1. Connect the inboard servo to the MatchBox and then
make all adjustments to servo center and travel adjustments
in the transmitter programming. No adjustments to this
servo should be made in the MatchBox.
 2. Connect the second servo to the MatchBox to center it,
then install the servo arm onto the servo on the spline that
gets it as close to parallel with the hinge line as possible.
Then use the MatchBox to set the center of this servo so the
servo arm is exactly parallel to the hinge line. Now adjust the
linkage length so the hole in the ball link directly aligns with
the appropriate hole in the servo arm.
Now deflect the servo to full stick in one direction and use
the MatchBox to set the endpoint so the ball link directly
lines up with the hole in the servo arm. Repeat this with the
stick fully deflected in the opposite direction. Once the center
and both endpoints are set for the second servo, remember
