I found several messages at the official MS site about the sim treating all throttle AXES inputs as collective inputs; moving the collective up/down and not moving/rotating the throttle on the collective.  All of the threads eventually end with no suggested fix or resolution. 

I have the problem with all my sim controls (Thrustmaster Airbus throttle quadrant  and addon and Joystick, CH Yoke, Saitek ST290Pro joystick acting that way in all three helicopter's I fly: Cabri G2, MD500, Bell 406. 

The USB game setup app and various other USB control monitors all show the appropriate axis being actuated as I move them on the controller.  All the controllers work fine with all the other fixed wing aircraft.  

I have tried every throttle control (including helicopter) I can find in the control  profiles and in every case using an AXIS for throttle input moves the collective.  

Assigning buttons to the helicopter throttle increase/decrease makes the helicopter throttle move as I wish without moving the collective.  

But - WHY can't an axis input control the helicopter throttle?

correct error

I believe it's a known issue that they plan to address in a future update.

The other day, I saw something in the SU12 beta release notes, about helicopter throttle.  So I'd say something is being done on that front.

Actually in the upcoming update which is now in Beta.

If it  can help this is the way I do it. I fly the piston Cabri with my Warthog throttle  :

- the rightmost  lever is bound to the "Collective Axis" function (reverse axis unchecked)

 - the leftmost lever is bound to the "Set Helicopter Throttle Axis" function (reverse axis checked) 

It works OK. When the governor is off, the throttle lever changes the rotor RPM.
