@avionic I'm running one of two Honeycomb Bravo setups, and I'm not sure which one is used for the 4-engine binds. By default, one knob will trigger the selection of an input, e.g., ALT, V/S, HDG, etc., and the encoder will then simply bind to MSFS "plus" and "minus" functions. My other setup uses key combinations so the selector sort of acts as a "shift key" for the encoder, and HDG increase and decrease will be bound to "HDG input + encoder up/down". The 146 didn't use to respond to whatever I was using.
I reported the vanishing keyboard in a ticket as well, that was the B-roll issue :-D
