Servo calibration should only be used for fine-tuning.

Careful and thorough mechanical adjustment is

strongly recommended. Never reduce the maximum

servo travels (

P1 and P5) by more than about 10 -

20%, otherwise you will forfeit servo resolution, and

any play in the servo gearbox will be amplified unnec-

essarily.

17.1.2. The procedure for calibrating a servo

a. Servos controlled by basic functions

(e.g.

Aileron, Elevator, Rudder, L. gear, ...):

First check that the servo rotates in the correct di-

rection (“sense”) relative to the control movement.

If necessary, change the direction in the Parameter

REV/TRM. If you later reverse the servo, you will

need to re-calibrate it.

b. Servos controlled by mixers

(e.g.

AILERON+, DELTA+, V-TAIL+, ...):

In the case of servos to which a mixer has been

assigned, the direction of servo rotation is initially

irrelevant, as the correct direction for the control

surface deflection can be set within the mixer itself.

c. Select a calibration point (

P1 to P5) and activate

the value (percentage figure highlighted). Now

press the digi-adjuster allocation button

<F>.

The servo (or servos, if multiple servos are con-

trolled by the same function or mixer) automatically

takes up the position corresponding to the per-

centage figure at the selected calibration point.

With one hand you can now easily and con-

veniently measure and check the control surface

deflection (ruler, calliper), while the other hand re-

mains free to change the value using the UP /

DOWN buttons Ÿ / ź or one of the two 3-D digi-

adjusters.

d. When the deflection is correct, press the digi-adjuster

allocation button

<F> again, and the servo (or ser-

vos) takes up the position corresponding to the po-

sition of the associated transmitter control.

The number of servo calibration points (min. 2, max.

5 points) varies according to the selected setting

when you initially assigned the servos (Î 17.2.).

 Tip: Vertical line for orientation!

The vertical dotted line shows the current position of

the associated transmitter control, and is an aid to ori-

entation. If you activate a value using the digi-adjuster

allocation button

<F>, the vertical line jumps to the

corresponding point and remains there until you press

the allocation button again, or move the associated

transmitter control.

17.2. Menu Assignment

Like the MULTIPLEX radio control series PROFImc

3000 and 4000, the ROYAL

pro

offers the facility to

define the receiver output sequence without restric-

tion. Compared with radio control systems with a fixed

receiver output sequence, this feature offers the ad-

vantage that, for example, the signal for a second ai-

leron servo (generally present at the higher channels,

e.g. channel 5) can be transferred to any channel you

like, and this can make it possible to use a small four-

channel receiver.

Servo, Assignment (Î next page).

Free assignment: defaults in the model templates

for MULTIPLEX or the standards of other makes.

All 7, 9 or 12 possible servos (according to the

transmitter type) are included in the list.

Up to five mixers can be assigned to each model,

each of them more than once.

How to carry out the assignment process:

a. Select the servo,
