- Store the initialised settings by moving the servo select switch to the
"SAVE" position and pressing the + button. The red LED now goes
out.
- The initialisation procedure only has to be carried out once. Even if
you wish to correct the settings at some later time, you will not need
to repeat the initialisation process.
Now you can make a start with the actual servo adjustment. To simplify
the procedure we will describe a typical example, e.g. an aileron with
two servos working in parallel:
- Connect one aileron servo to the control surface linkage. We
recommend that you now adjust this servo both mechanically and
at the transmitter in such a way that:
• the zero (neutral) point is correct;
• the appropriate maximum travel is set;
• the Expo functions are set.
- Now select the second servo on the adjustor board and hold the
pushrod against the aileron horn (don't connect it at this stage).
- Leave the aileron stick at centre. Press the + or - button on the adjustor
board to bring the pushrod to exactly the right position. The red LED
will light up to indicate that the current servo position is not yet stored.
- Move the stick to one end-point and hold it there. Hold the pushrod
against the horn as before, and move the servo to the correct position
using the + or
- Move the aileron stick to the opposite end-point and again use the + or
- buttons to move the servo to the correct position.
- To save these settings move the servo select switch to "SAVE" and
press the + button; the red LED now goes out. The two aileron servos
are now matched, and the settings are permanently stored in the
memory.
Additional hints and tips:
- In the case of large ailerons in particular, it can be advantageous not
to match the servos with 100% accuracy. If the servos are precisely
matched, gearbox play in the servos may allow aileron flutter to
develop. You can eliminate this danger with a highly precise offset:
first match the servos exactly to each other, and then offset the servos
against each other by pressing the + or - button two or three times
briefly - just sufficiently to compensate for the lost motion in the servo
gearbox.
