Try rotating your graphic 90 degrees counter-clockwise. It looks like it is taking the "forward" vector to be facing downwards.
Is it better now? It's a bit difficult for me to tell when the ship's constantly spinning!
No, still the same. The pointed end I am guessing should be facing forwards?
Reduce the "Torque" to a lower value like 0.05 or less. This reduces the turning power.
