Master CP - Swash plate problem

Hello,
please excuse my bad English. I’m from Germany and there might be some mistakes in the post below.

My problem:
Last weekend I flashed my Devo 10 with the deviationtx software. Then I loaded 3 settings for the Walkera Master CP (Ultra Beginner / Beginner / Standard) which are available in the Model-Config Thread.
Before I switched to deviation I used the original devention firmware and the standard Master CP file from Walkera.
With these settings the helicopter was perfectly trimmed and was absolutely stable at hovering.
The swash plate was perfectly leveled.

But with each of the 3 deviationtx files the helicopter isn’t trimmed/set up at all.
The swash isn’t leveled at all and the servo arms don’t have the same position after binding as they had with the devention firmware.

Question:
Is this normal? Did you have to set up your swash plate, too when you switched from devention to deviationtx?
If not, what am I doing wrong?

Thank you very much in advance!

I am not sure if there might be any small nuances in a different servo neutral µs pulse signal between Walkera stock and DeviationTX?
I am also not aware that you can change any mid servo impulses on DeviationTX.


MasterCP = FBL

Well, you are NOT allowed to use subtrim for servo arms (90 degree) or swashplate.
One thing you can do for H1/1Servo/None CCPM settings is to use subtrim on pitch channel (only!!!) to fine-tune for 0-degree zero pitch and mid stick - especially if the FBL does not support it by itself (same works on NanoCPX, MCPX, etc.).
You can then use Servo travel adjust / Scale +- on pitch channel to set max/min pitch travel.

AFAIK neither the V120D02s nor the MasterCP FBL receivers have support for swash leveling or servo arm 90 degree orientation.
So you all have to do it mechanically.

On a FBL system you are also not allowed to use the trim switches (around sticks) for cyclic.
Only allowed for flybar / paddle helis.
Usually better FBL systems support swashplate trimming (cyclic nick / roll).


So I suggest you change servo horns and swashplate mechnically to be level / 90 degree.
You can try German forums RCLineforum.de or RC-Heli.de for details on how to do this. There might also be a view DeviationTX pilots active.

Let's hear a bit more from the MasterCP pilots or DeviationTX protocol developers...
Sorry, I do not have the MasterCP or the Walkera V120 FBL.

Thanks, Thomas!

I just wonder why all of the 3 files (Ultra Beginner / Beginner / Standard) have different positions of the servo arms after binding.
So I would have to do a mechanical set up each time I choose another model!?

Is there something like a “calibrate mode” within the software for the helicopter?

Just checked manual. You can only set the "center pulse width" (Center PW) on PPM protocol, not Devo or DSMx protocols.

Check your channel monitor: ENT / 2 Transmitter menu / 2 channel monitor

Stick calibration: ENT / 2 Transmitter menu / 1 Transmitter config / Generic setting / Sticks (3rd) CALIBRATE button
