I've tried using MechJeb to dock to my space station with this, but when I turn the docking autopilot on, the orbiter starts rolling out of control, distancing itself further from the station, and then the target automatically changed to the station itself (instead of the docking port I wanted to use). I have no such problems with other spacecraft, however. Are instances like these examples of the RCS functioning poorly or what not? If not, what might be the issue? (I'm such a noob LOL)
