Hi,
I had similiar issue , heading bug , compass and so on , moved in 10 degree steps only.
In contrast to you , I own an “Thrustmaster Warthog Throtte” and also fly active DCS with the A10C.
I find out what happens, because also the FLAPS not really worked:
- MSFS does auto assign the flaps-up/down to the FLAPS switch , BUT it doesnt works as the real switch is !
The switch is “UP/Manoever/Down” … MSFS does not use these positions, it simple use the “click-events” to increase/decrease the flaps position.
Thus, because I normaly leave DCS in the UP/DOWN position, MSFS seems then to receive allways USB events (flaps up) and do somewhat with it.
I simple I have to remember allways to go for MSFS in “MR” position ( finally simple removed the asssigment , because its not usable in MSFS ).
This points to what @David4DW mention : assigmment issue where then allways events send into msfs too
