I installed the RF9 today and added the WS2000 dongle. I bound my DX7S to it and then calibrated it. The calibration showed that everything was working as it should be but when I into the flight sim and fly a model I have no down elevator despite this working showing as working in the calibration. Has anyone else experienced this problem or got any ideas/solutions on how to resolve this as I tried several re-calibrations and still no luck?
