So I thought it was my Gun Fighter 3, it appears that the issue lies with the combination of the VKB Gun Fighter 3 Pro and the F-18c module.
There is a very serious y axis issue with makes the plane 100% unflyable; Immediately after wheels up the plane goes into an uncontrolled nose up (Y axis) accent, the plane will complete a loop with no stick input what so ever, forward pressure on the stick only modestly slows this nose up flight profile. I have tried many calibrations, dead zones, disconnect and reconnection of the stick and finally I have flown with the stick using other modules such as the F-16c and the F-14b. There is no issue when I use the warthog to fly, I would really like to use my GF3. PLEASE HELP!
Cheers,
L
