The following examples illustrate the correct procedure for the
Servo-Match function:
a) Fine-tuning multiple servos to operate on a single control
surface; in this case the aileron of the right-hand wing.
- Disconnect the linkages to the - as yet unmatched - servos, to avoid
them being subjected to severe forces during the adjustment
procedure.
- Assign the output to the appropriate socket in the
OUTPUT
MAPPING
menu.
- Set up one servo (generally the inboard one -
SERVO 1
) in
mechanical terms, using the transmitter if necessary; continue
adjusting until the centre point and the maximum end-points are
exactly as required.
- Now access the Servo-Matching menu and select the servo to be
matched. In our example this would be
OUTPUT B
and
SERVO 2
.
- Initialise
OUTPUT B
as described above.
- Move the cursor to
START SERVOMATCHING
→
but do not press
the SET button at this stage!
- At the transmitter, move the aileron stick to the position to be
adjusted, then press the SET button.
- You can now release the aileron stick: the
PowerBox
maintains this
position. You now have both hands free, and can adjust the position
accurately with one hand, using buttons I and II, whilst checking the
length (matching) of the disconnected ball-link at the horn with the
other hand.
- Press the SET button again to conclude this adjustment.
- Complete the set-up procedure for the centre position and both
end-points before re-connecting the servo linkage.
- If you need to carry out further adjustments to another end-point or
centre position, move the aileron stick in the desired direction again,
and press the SET button again to start the procedure.
- Repeat the procedure with all the servos connected to the same
control surface.
Note:
if your model is fitted with very large ailerons, it can be
advantageous not to match the servos with 100% accuracy. If the
servos are precisely matched, gearbox play may allow aileron flutter to
develop. You can eliminate this risk as follows: first match the servos
exactly to each other, and then press buttons I or II two or three times to
reduce the effect of lost motion in the servo gears to a controlled extent.
