I fixed this by changing the sliders in the controls section of the options menu. I set 0% at 0 (full left) and 100% at 100 (full right). The game now recognizes my full throttle (
Saitek av8r) arc, which makes for much more precise throttling. It's a bit oftrial an error with dead zones etc... but you should try that.
Cheers
