I went through the "properties" panel for the g2 controller (I renamed the device as "game controller" ) and had to change which channels controlled the proper surfaces. Once I reset the proper channels to the proper surface I calibrated the controller. It works great and I prefer flying AFPD with the G2 controller vice my JR 10X. The only issue I have now is that the dual rate switch doesn't work on my g2 controller. Anybody have any ideas to make it work?
I hope this makes sense and answers your specific question.

Good luck and smooth flying, Spit
