voice throttle controls did not work well for me and my X52.
sometimes it worked, sometimes it did not (but it's the same with X key).
the stick tends to send commands permanently in some stick positions (which i can see when opening the control options).
But i like it better with manual speed control anyway.
For energy management VC is perfect.
Took me a while to get it working though. But it wasn't VCs fault, my microphone sensivity was set much to high, so every breath or headmovement produced input which was added to my spoken commands (and so not recognized).
