Very interesting and helpful analysis Problemsolver. I used to have a problem, on any course, with pinballing at high speeds. If I hit a right hand wall I'd be turning left from just before I hit it (not enough to prevent me hitting it), and shortly after hitting it, and then I'd find myself going way too far left and hitting the left hand wall, then back to right etc etc.
Then I had the idea that the wall itself makes the craft rebound in the opposite direction, eg hit a right hand wall and it rebounds the craft left. So to counteract this, when hitting a right hand wall, I would turn right to make the craft go straight. This did seem to solve the problem.
But now from your post it seems this isn't the case. When steering right, I am not doing it as frantically as my left steering, and am infact probably inputting the steering right command in the time frame of when "no input is registering". And so really it has the same effect of not doing anything at all
As for steering being more sensitive now, what about airbrake steering? Is this also more sensitive, or could using the airbrakes for straightening out the craft be the solution?
