I tried using the trackball for left and right turning, and I also tried to use the spinner. I am having the most luck with my 8 way Happ Super...
What are the problems with the TB & spinner? If it's returning to center and you don't want it to, you can go tab, analog controls, and set the
Paddle Autocenter Speed to zero. This will, however, make the 8-way a lot worse of course, so set it back to the default: the same as
Paddle Digital Speed, or to your preference if it doesn't help TB/spinners for you.
That said, I agree with megaultrasuper that any analog joystick will do better than an 8-way stick, and almost as good as most PC wheels.
