Remote Control als Joystick, how to configure?

Hello,i want to use my Remote Control Graupner MX-12 as Joystick.The device is detected and works.But i have some Questions about configuring the joystick:js_demo shows:Ax0 = Throttle: Stick down -0.7 to + 0.7 Stick upAx2 = Elevator Stick down -0.7 to + 0.8 Stick upAx3 = Rudder Stick left +0.8 to -0.7 Stick rightsample configuraton entryaxis n="3"> Rudderproperty-scale/controls/flight/rudder1.0First Problem: Up/Down and Left/right are swapped:e.g. Putting Rudder Stick to right, the airplan fly left. Putting Throttle Stick to top, it should be full throttle, but Throttle is out.So how can I configure something like INVERT??Second Problem:. ailerons will be controlled separate.That means putting "aileron stick" to right Ax1 = Alileron +0.7Ax4 = Aileron -0.7and reverse.How to configure left/right aileron?Aileronproperty-scale/controls/flight/ailerontrueAileronproperty-scale/controls/flight/ailerontrueI would be thankful for any hints.RegardsMarkus
