Since patch 3.24, the HOTAS throttle no longer maps linearly from 0% to 100% (bottom to top) because it became a bidirectional 'Velocity Control' with zero at the center. The user asks for this to be fixed so the throttle works like it did in 3.23 and like real HOTAS hardware.asked by Bonzenbaron

We didn't remove these actions but relabelled them due to some maintenance work. You can still fully bind them as before, search for throttle instead of thrust in the spaceship movement category.

The presets we're shipping are definitely out of date and need to be updated. But you can absolutely bind the axes normally.
