Unbalanced RCS thrusters

[nhnifong]

When using different types of RCS thrusters ships will sometimes translate as well as rotate when the rotation keys are pressed.

It seems that the code which determines how strong to thrust each RCS thruster doesn't care how strong they are or it would compensate.

I think it just sets their trust percentages and not the desired amount of newtons.

For example, try placing linear RCS trusters on the bottom of a small ship, and radial rcs thrusters near the top. any attempt to rotate in space will also translate you. you can tell this by looking at your speed or looking for changes in your orbit.

Does anyone know if this is by design, or if its a bug? Does anyone know how to work around it? I'm having trouble building a balanced micro-rover (with mj instead of a pod) it needs to be able to rotate without translating itself using only rcs. Could it be a mechjeb problem?
