I recently bought a Logitech F510 gamepad for use with FS2 as well as other games. However, when trying to implement a control scheme that utilizes the dual analog sticks, I found that the game was not reading the horizontal axis on the right analog stick during play. FS2 does however acknowledge the existence of the axis as I can bind it. The windows calibration screen confirms that all is as it should be with the gamepad.
The only thing i can think of is that FSO only supports 4 axis, where the gamepad has 5 (2 analog sticks, each with an x and y, and 2 shoulder buttons operating on the same axis).
I dont really know where to post this, but you guys make the game work, so I figured here was as good a place as any.
