I solved this by mapping both sliders + & - to Collective Raise (Analogue), albeit a bit confusing, Works like a charm. Thank you all.

Yes, this has been solved. If you are getting 50% throttle then you need to unmap your other analog device. Only map the logitech otherwise it will split the input with the another analog stick (50% + 50% = 100%).

Has anyone found a solution to this?

has anyone fixed this? I'm having this same issues with my current ARMA 3 server. Version is 1.44, I'm running the server with mods.

TIA
