Physics in the Space Agency universe can be a funny thing. Sometimes you press the rotate button and the ship you are piloting spins faster than something of that mass should. Other times after several rounds of tapping still leaves the ship spinning slower that a glacier.
One method that pilots at Centauri Spaceworks use for rotating stubborn ships is the double sideways method. This method can be applied to any ship that has a forward and reverse facing engine unit.
To execute:
1. Tap the side (left for clockwise, right for counter-clockwise) on the forward facing engine. The ship should start to rotate and drift to the side.
2. Tap the same side button on the reverse facing engine. This should kill the sideways drift but keep the rotation.
You can repeat this process multiple times to spin the ship faster.
If you have only done the procedure once, stop you can probably use the rotation button to stop the ship without having to reverse the double sideways maneuver.
