Well, unless HT is using a completely "new" flight modeling system, the nose bounce IS a product of the flight model. The way the old explanation went, IIRC, if the airplanes are made to be "stable," (i.e. more resistant to spin and snap roll) then they become "bouncy." When they put in the more macho spin modeling in WB 2.0, the nose bounce was decreased significantly.
So, it may be that the problem will solve itself as the flight model is tuned to the next degree of difficulty. Or it could be that this model is completely different from HT's earlier model and I'm completely out to lunch

Either way, the only thing WE can do is tweak the joystick settings. At one time I had the OLD WB (pre 2.0) nose bounce pretty well minimized (and I know I had it as bad as anyone before that). The stuff to try:
--Clean your joystick pots
--Try another joystick port
--Try both digital and analog ports and sticks
--Use a third party calibrator, such as TM's ProPanel (
www.thrustmaster.com). It works on generic sticks and CH as well as TM gear.
--Trial and error adjusting of dampener and stick throw curves.
--Try "polling with interrupts" in Windows controller setup.
--Try "polling withOUT interrupts" in Windows controller setup.
The biggest thing to check, tho, is that your controllers work "normally" in Windows. That's the baseline you MUST start from. If you get ANY spiking, you're just asking for nose bounce. Spiking in the Windows calibration is PROBABLY a joystick problem (i.e. worn or dirty pots). Fix that first. Then try calibrating with a good third-party utility. Then reduce your stick response in the sim so that small stick movement produces small aircraft movement. Then increase dampening so that it "feels" right to you. Then gradually tweak the actual curves so you can get full control response at some point. It goes without saying that you should be using the same airplane for all this testing. You may find that you need completely different curves for the Spit IX and Corsair, for example.
None of the planes I've flown are quite as bouncy as the old WB or the new AH. But you should be able to tweak a decent joystick/port combo to minimize the worst of the bounce.
Don't expect to get it right quickly tho. It takes a combination of tweaking and practicing with it to "defeat" nose bounce. Try flying with two fingers, and using the keyboard to fire guns instead of the stick trigger.
I know, I know, "stopgap measures" at best, but if they decide to leave the flight model unchanged in this area, it's about all you can do.
