Controls Issue - Very Annoying

[Racetrack]

Guys, me and other friends have an strange issue with some controls in this Sim...

When I play online in Dedicated server like Atag or others we have no problems and everything work smooth and fine, instead when we play in this modes:

-Singleplayer
-My own hosted server
-My friends hosted server
-Preview from Full Mission Builder

We have a very annoying problems that makes us unable to fly at all.


THE PROBLEM

It seems that ALL my controls mapped on my X-52 Throttle don't work constantly, the result is that when I move for example the main Throttle I don't have a constant response in-game.
Just for being more clear, it seems that the Sim check the position of my Throttle every X seconds (where x is a random time), this means that when I push for example another controls on my
Throttle like the "Toggle AirBrake" nothing happen.... I keep pushing (with rage XD) an 1000 times and than POOP my airbrake go down and immediately up LOOOL..
This happen for ALL my controls mapped on my X-52 Throttle..

THE STRANGE THING

We usually have two key for the command.. For example the control "Toggle Airbrake" is mapped on the Throttle and on the Keyboard too, one nor the other work......

Does this depend on Saytek controls?
Any Helps??
