1. Assign an axis to brakes (helps a lot)
2. As you move forward, hold down wheel break (or apply pressure to the brake axis) and twist rudder.
3. Your plane will start to turn. Takes a bit of practice.
On my X52, I've assigned the brake axis to my thumb slider axis on the throttle. It means I can apply a bit of pressure to the brakes to make slight adjustments in my direction. It's helpful for lining up on runways.
