Of course in fictional space dogfighting, you can't actually stall since you are not flying aerodynamically but instead changing course with engine thrusters
Thanks for the info Chock. I guess better turning rate could be explained that some of your "engine power" isn't applied to forward acceleration, but lateral thrust to bend your curve.
Although that would mean that rotation speed (not turning) would be highest when not using your main thrusters (e.g. slowest forward acceleration = highest rotational speed).
Of course the ultimate answer is "because it's more fun"
