p3dv4.5 Response curse half way working

[Braudoux]

Hello,

I just replaced my Saitek X55 controllers with HOTAS Warthog. I noticed, after assignement of throttles, that when I move the levers in A400M (Roland Laborie), the displacement in the cockpit is completely erratic, jumping from idle to full and vice versa when moving very slowly the levers.

I have double-checked the assignments within P3Dv4.5 and removed all default assignments... there is no binding in P3D. Also I do not use any other tool than FSUIPC to bind my controllers.

While attempting to calibrate the throttles, I noticed that the curve for each is working half way only, and not all along the curve (See screens). Consequently, if my controller's levers are on idle and I move them forward, the first half is not generating any action and the levers in the cockpit start moving when I reach the second half, which gives me a very short range to manage the power. 

I have tried both configuration with and without Reverse zone and it goes the same way...

I have also checked my controllers with a twin engine TP and Fighter aircraft and it is almost the same with less erratic movements.

I am sorry if you feel this post quite confusing but is is not easy to describe all different points linked to the situation.

I am ready to provide any additional detail to help understanding the case.

Thank in advance

Bruno
