I wouldn't touch the dead zones, and would leave those at 0, but everyone should adjust the sensitivity settings for their joystick, yoke, and rudder pedal controllers. I use a CH Products Fighterstick and CH Products Rudder Pedals, and I have the sensitivity set at -25 for all of the aileron, elevator and rudder axes. To me, this is a perfect setting for those controllers, but some may find different results with different types of controllers.
