Just wanted to say I'm having the same issue with my Honeycomb Bravo in the 4B, GNS.
FWIW, I was using the same binds/profile I used previously with V1 of the MU-2. When I have my Throttle Levers set to Throttle 1 and Throttle 2, the levers move in sim but don't control anything. Once I set it to just "Throttle" it works fine.
