Hi, Could someone please point me in the right direction for the setup of a Robbe / Schluter rocking servo setup? One servo is for the collective, one for the roll, and one for the elevator. The mix is done mechanically. The model was set up with a Futaba CGY750 but the OLED display has failed so I can not read the settings. I will be using a GTR with a Jeti TX. I have tried all the different swashplate types but none seems to suit this type of setup.
-------------------------------
So after changing the swash plate to 90deg CCPM and setting the phasing to -45 deg (CCW rotation) the head all seems to move in the correct direction (90deg out of phase for a 4-blade head).
Now to continue the setup
Please chime in if you have any further information on these setups.
Thanks

Nobody seems to know, even ZeXx86 
Maybe there is no solution or the question is rather difficult but it is the first time since 9 years I own Spirits (with a great satisfaction) that I see a technical question direct related to the product unanswered. Thanks anyway

I created a solution with a Bavarian Demon unit some years ago with a 1 servo 1 function set-up. I will see whether I still have the file, but was a long time ago!
The pilot was a tool maker and subsequently changed the control to a direct control with good effect. However, did work fine in the original form.
I will see if I can find the original tonight.
Although the mechanical set-up looks very different, the ultimate behaviour is no different from any other current direct control arrangement. You still have to achieve the standard cyclic and collective actions!
Just look at what input achieves those actions and go from there.

I have tried to find that file and can't currently see it.
As I remember, I took no particular different view of the servo functions, just review what each servo in this format actually tries to achieve - aileron, elevator, collective.
Then just apply the normal programming logic. This did work fine, although, watch out for slop, etc.
