KSP Recall :: Heading Drift Problem

On TweakScale's thread on Forum, a brainstorming ended up intriguing me to the point to spend some time doing tests on the subject.

The result is the Release for KSP-Recall.

This is a Test Drive for the solution.

Using Vessel Mover, I took two Aeris 3A and placed them face to face (one Heading 90o, the other Heading 270o). Just for more testings, I EVA'd the Pilots and place them between the crafts.

The crafts are with the gears raised, to eliminate the drifting of the wheels themselves (that are a different problem, believe it or not!).

This is the setup after 3 minutes of Mission (more or less the time I took to place the pieces on the table).
