Good find and so nearly awesome! Alas it doesn't seem to do the throttle, only the main stick axes.
Aah bummer. A bit strange though, I was under the impression that a throttle axis is a throttle axis, regardless of it being a tiny slider on the stick or a separate unit.
Yeah I have three of the damn things. I don't want to change to a new hotas system because my muscle memory is tuned to the t flight.
I'm in exactly the same boat.
Make that three.

I've been more than happy to restore my venerable T.16000 to active duty, and it served me very well during the latest
shenanigans Speedbowl, but the sudden loss of throttle and complete change of binding setup has been jarring, to say the least. Got back to standard game activities using my jittery and imprecise, yet so much comfortable Hotas 4.
(Next one will be a Gladiator NXT though, no doubt about that.)
