Get relative axes of a ship part

[Ontresanas]

I'm trying to make a simple mod to figure out how everything works, as it were - I want to draw a line from the root part for gravity, thrust, and the three relative axes of the root part (forward, up, and right).

Currently, I'm using the following. The ForwardAxis gets a constant vector which reliably points out the side of the root part; the other two axes do all sort of crazy wonkiness and don't actually stay fixed relative to the part in question.

Vector3 ForwardAxis = FlightGlobals.ActiveVessel.rootPart.transform.forward;
Vector3 UpAxis = FlightGlobals.ActiveVessel.rootPart.transform.up;
Vector3 RightAxis = FlightGlobals.ActiveVessel.rootPart.transform.right;

Why do UpAxis and RightAxis not work the way I would expect them to, and is there a way to get the part's relative up and right axes?

Having fiddled around further, I realized what I was doing wrong and fixed it. However, I can't seem to figure out how to get the current target; FlightGlobals.activeTarget seems to just be the root part no matter what I do.

Is there any way to add a new indicator to the navball?

How'd you fix it? I'm having a similar problem.

You can look at this mod for how they altered the navball http://forum.kerbalspaceprogram.com/threads/50524-0-90-Enhanced-Navball-1-3
