Heli Setup (page 2/13)
A short press of the RIGHT key will bring up the helicopter CCPM head mixer screen. This page
allows setting swash plate type, and limiting the control authority through the Swash Ring setting.
Note that many modern rotary wing models, whether flybarless helicopters or multirotor machines,
use an on-board flight controller that cannot accept CCPM mixing. Likewise, coaxial helicopters
typically require only simple fixed wing type inputs for the rotors (aileron, elevator, rudder) and
throttle to control climb and descent. For such models, you can ignore this page.
The inputs to the CCPM mixer are the AIL and ELE sticks, plus the input or virtual channel selected
in "Collective" (which has entries on the MIXER page for one or more pitch curves). Here are the
details:
Swash
This defines the type of swash plate used by the heli:
120
: “Standard” 120 degree swash plate. The “pitch” servo is towards the front/back.
120X
: Same 120 degree swash plate but turned 90° so the pitch servo is on one side.
140
: Less common 140 degree swash plate – the “pitch” servo is towards the front/back.
90
: Basically a simple 90 degree setup where a single servo operates the collective pitch directly
and aileron and elevator servos tilt the swash. May be used for fixed pitch helis.
Collective
This defines the source of the collective input. The idea is that you can create a mix in a virtual
channel (above those sent to the receiver) incorporating all the required curves and switches,
then simply use it as the input here to mix with the other inputs.
Swash Ring
As the name implies, this feature limits stick movement just like a physical swash ring. Notice that
this feature only works on AIL and ELE, regardless of radio mode selected.
ELE/AIL/COL Direction
These allow the direction of the input functions to be inverted. Use them to make the controls
move the correct way when setting up your heli.
The outputs of the CCPM mixer are CYC1, CYC2 and CYC3. These need to be assigned on the
MIXER page to the channels that will drive the swash servos. The settings made here have no effect
unless you use the CYC1, CYC2 and CYC3 outputs.
