As far as cyclic goes, each cyclic represents one of the servos that are attached to the swash plate.
On a heli with mechanical linkages, you have 3 controls affecting the swash plate:
You have fore/aft pitch
you have left/right roll
you have collective lift.
and you have 3 servos attached to the swash, but the servos do not map 1-to-1 with the controls.
On a 120 setup:
the front servo (cyclic1) is affected by collective and elevator only
the back 2 servos (cyclic2 and 3) are affected by collective, elevator and aileraon.
Each servos needs to move in a different way to achieve the proper swash position.
Here's a cyclic setup for the 6ch heli:
Servos 1, 2, and 6 are attached to the swash plate. In FBL, the receiver will take aileron, elevator and collective on channels 1, 2, and 6 and will do the mixing. On a non FBL helicopter, the Tx must do the mixing

I want to verify that I understand what you are saying:
Assume top of image is the front of the helicopter.
In the 120° swash Cyclic 1 is simply what the elevator servo does.
Cyclic2 is a combination of what servos 2 & 3 are doing moving in opposite directions.
Cyclic3 a combination of all three servos going in the same direction.
Is my understanding correct? How does this relate to a 120X swash?

Hi Guys
We need to provide templates and examples in the documentation for FBL heli's that use:
1) FBL gyros that needs the mixing in the TX as shown above, ie. the Align 3GX with 120deg swash setting on the Trex heli's).
2) FBL Heli's like the small Walkera models (Super CP, V120D02s, etc) that do the mixing in the receiver/Gyro unit.
Both these are 6ch FBL heli's but with very different models
or templates required.
This is my V120D02s model with full Main screen toggles for all Devo8s switches:
\Layout Dir: Default.ini with full mapping for the Devo8 switches:

Line 757 is still too much
. I think you can also get assistance from the folks around here for porting to the color screens.
We could spend much more time to get some parts even more clear or to get a programming handbook for every heli or up to a 6-flaps glider. In general I am very satisfied with the outcome.
