Assignments for non self-centred Puma cyclic

28 Apr 2022 12:54 #4644 by ianD
I am a little embarrassed to ask this question being an ex-military and civilian QHI/TRE/IRE with 12,000 hours flight time. I am struggling to get control of the SAS and autopilot in a satisfactory way. I have tried all manner of assignments both from the EC 135 plug-in and from X Plane’s native autopilot available assignments. I think I have come up with a suitable arrangement which seems to work - then it doesn’t. Please would you advise me of the best settings to use and would I be correct in assuming that trim shift is superfluous with a non-centred cyclic. I fly exclusively in VR and find your helicopter (I have the plus version) very realistic although I only have 70 odd hours using it and much to learn. I have several hundred hours in X  Trident’s AB 412 and have tweaked that in various ways to suit me and would love to have the EC 135 in the same state.
Thank you in anticipation

In the Plus version there is a setting for a joystick equipped with a hardware force trim function. You could use that.In the [SETTINGS] section of the ec135v5.ini add the line
JoystickHasFtr=1
(Documentation: www.rotorsim.de/ec135v5/users-guide?start=12)

This option will bring roughly the behavior you need: 
Without the autopilot, the FTR button and the beep trimers have no function. They expect the hardware to work itself.
With autopilot, FTR makes a change in reference attitude. The beep trimmers also change the references depending on the mode of the AP.

However, there could be a problem due to the cyclic not returning to its previous position after an override when using the autopilot. An override is terminated when the cyclic returns to the position from which the override was started. Hitting that position again without a force trim spring or something to help is more of a gamble.

Thank you for reply which sounds as though this is the solution to my problem. Unfortunately, I am away for a few days but am looking forward to trying it out on my return and will advise you of the outcome.

I have followed your instructions and it has solved my problem very well. It makes flying with the Pro-Flight Puma a much better experience.
Thank you
