Re: Joystick issues
I use a Microsoft Sidewinder Force Feedback 2 myself. $200 well spent over a decade ago.
Personally, I swear by Realmware's BF4 Settings Editor. It is a quick and easy way of setting up your joystick config. Go through and choose to clear all joystick configs everywhere, and then start from scratch. It sounds like something's conflicting with another setting (easy to do when the button descriptions make no sense).
That said, I haven't tested jets in BF4 yet, only helis (still waiting for release here). Will post again once I've tested what you're referring to.
Edit: I don't have the same problem. I can shoot while turning. I strongly advise clearing and resetting your joystick config with BF4 Realmware Settings Editor.
However, I do notice that when braking the jet it is very slow to turn - before the jet has fully slowed down. It looks like "fast" is the optimum turning speed now. Maybe they're reading the analogue signal from the throttle. I'm not sure.
