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 outboard 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 inboard servo to the MatchBox, 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.
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 to
turn the dial on the MatchBox back to the 0 position to save
the settings before powering off the receiver. Hint, when
adjusting for endpoints (full deflection), it is hard to hold the
sticks and adjust the MatchBox at the same time. It is best to
move the sticks to full deflection and while holding the stick,
turn off the radio. This will put the receiver into hold and
makes adjustment easier working only the MatchBox and
observing the linkage position over the servo arm.
