16.2.3. Assigning servos for helicopters 
  Model type „Helicopter“ 
  Note 
Aileron 
Roll signal only  No mixing 
for mechanical rotor head mixing 
Elevator 
Pitch-axis signal only  No mixing 
for mechanical rotor head mixing 
Rudder 
Yaw signal only  No mixing 
Throttle 
Throttle signal with mixed throttle curve, 
throttle limiter, direct throttle, throttle-cut 
Spoiler 
(for fixed wing models) 
RPM 
Speed regulator control 
L. gear 
Landing gear signal   No mixing 
Tow rel. 
Tow release signal  No mixing 
Brake 
Brake signal  No mixing 
Gyro 
Gyro signal, including all mixed signals 
from gyro mixer 
Mixture 
Mixture signal for special carburettors  
Collect. 
Collective pitch signal  No mixing 
for mechanical rotor head mixing 
Thr.lim. 
Throttle limiter signal  No mixing 
TAIL 
Tail rotor signal, including all mixed signals 
-> tail rotor (e.g. static tail rotor compensa-
tion / Revo-Mix) 
HEAD f/b 
HEAD le 
HRAD ri 
HEAD 4 
Signal for swashplate servos ** 
HEAD f/b, le and ri for swashplates with 
3-point linkage (e.g. 3-point 120°) 
HEAD f/b, le, ri and 4 for swashplates with 
4-point linkage (e.g. 4-point 90°) 
(electronic swashplate mixing, CCPM) 
** Note  
To ensure that the electronic swashplate mixing works 
correctly, the servos must be connected to the receiver 
in a particular, pre-defined sequence. (è 15.5.) 
16.3. Sub-menu „Monitor“ 
The servo monitor acts as a substitute for a receiving 
system with servos connected. It enables you check the 
function / response of speed controllers, gyro systems, 
speed regulators etc., and helps to locate errors. 
Two forms of display are available: graphical, with the 
output signals displayed in bar graph form, and numeri-
cal, with the signals displayed in % values. You can 
switch between the two types of display using the 
UP/DOWN (s / t) buttons, or alternatively using one of 
the two 3-D digi-adjustors. 
 
 
16.4. Sub-menu „Test run“ 
Automatic servo run, which can be used for test pur-
poses and demonstrations, or as an “electronic” aid 
when range-checking. 
 
When you select a transmitter control, the software 
generates a steadily changing control signal, running 
from one end-point of the control to the other. All the 
servos operated by this transmitter control (directly or 
via a mixer) start running. 
You can stop the test run by either of two methods: 
•  Press the REV/CLR button ⇒ „Control “ appears 
•  select no control („ - - - - - - - “) 
The transit time can be set within 0,1 – 4,0 sec.
