My main concerns with spinning are entering the steep spiral mentioned above, or the engine stopping.
I've heard a lot of people say they've had an engine stop on them, but i've spun about 25 times now without the engine stopping. How common actually is it? Does spin direction really make any difference to this? I've spun both ways without problem.
Every time I spin I keep expecting the engine to stop, or even sputter, but so far no problems at all.
