Groundvolume and other knobs not fully mappable

[xfirf]

I tried to map Groundvolume to a axis-knob of my Control Panel but only 50 percent of the axis are acutally used. This also affects other knobs in the cockpit of the Harrier.

When trying the same on a F-18 it works as intended: I can use 100 percent 1:1 from axis to knob.
