sadly that is way too low, turning around is nearly impossible. but for a spacecraft it's really slow too, i estimate a bit faster than a car (EDIT: no, a bit faster than you walk), with warp jumps of a few hundred metres before the engine needs recharging, wouldn't mind if it wouldn't take minutes, but seconds to recharge. it's a bit like you expect an airplane but get a hot air balloon.
Sure rotating shouldn't be as fast as a person but for a such small ship taking hours (or at least about 15 minutes) to turn is just not enjoyable. it shouldn't be that much slower to rotate it around aother axis, at least if the one who built that ship didn't totally messed up.
Okay that rotating problem seems to be only in tutorial and storymode, in sandbox it's fine. Or at least better as you don't need to move your mouse a metre to move the crosshair/circle about a centimetre.
oh, and you shouldn't stop moving just because you aren't accelerating, there is nothing (or at least not noticable much) stopping you in space.
But it has quite some potential.
