Have the Bravo and the lower half of the throttle dont respond to input and then they jump to 1/2 3/4? Tried sensitivity but nothing seems to works. Any ideas?

Have you tried the other axis after setting as throttle?  In Windows Search bar type Set up USB game controllers then select the Bravo Throttle Quadrant then properties and check Axis sliders and see if they respond.  If they are smooth there you'll know there is interference in the sim settings.

Ahhhhh, good point. Will try shortly.
