Thanks to Jan for walking me through this.
I was missing a servo assignment, which is copied out from another plane into the TMD. My starter TMD was the Template which has no dynamics or servo assignments and no animations, which I knew, but didnt know about the servo section.
This is my rudder animation block, which goes below the primary parts block and in the 'graphics' section. (Graphics is the polygon structures with graphics on them).
Animation block;
<[string8][object][hingedbodygraphics]
<[string8][Name][RudderBullette]>
<[string8][GeometryList][ RudderBullette ]>
<[uint32][PositionID][Fuselage.R]>
<[uint32][OrientationID][Fuselage.Q]>
<[uint32][AngleID][ServoRudder.Output]>
<[tmvector3f][Axis][ -0.0000 1.0000 0.0000 ]>
<[tmvector3f][Axis][ -0.9962 -0.0000 0.0872 ]>
<[tmvector3f][Axis][ 0.0872 0.0000 0.9962 ]>
<[tmvector3f][Pivot][ -3.1649 -0.0001 0.4654 ]>
<[float64][AngleMax][1.0]>
<[tmvector3d][Shift][ 0.0 0.0 0.0 ]>

The next code goes above this, below Dynamics, above Graphics;
// rudder
<[string8][object][control_input]
<[string8][Name][RudderInput]>
<[string8][Input][Controls.Yaw.Input]>
<[tmvector2d][Range][ -1.0 1.0 ]>
>
<[string8][object][servoclassic]
<[string8][Name][ServoRudder]>
<[string8][Input][RudderInput.Output]>
<[float64][Speed][10.0]>
<[float64][P0][0.0]>
<[float64][P1][-0.4236]>
<[float64][P2][0.0]>
<[float64][P3][-0.13]>
<[float64][Position][0.0]>

For those that are animating, you refer to your TM.log that exports with your aircraft model from 3DS Max or other 3D program. ON that log is a list of parts blocks. It has the Gizmo location and its angle, then it has three swivel angles. Your part will animate on one of those axis swivel angles. In AF2, the last one is used in the game engine, so if your rudder is moving on the wrong axis, you change to the next swivel axis, etc.
Below is the block for the rudder from the TM log, how it looks, un-edited...
0.61-tmmodule: <[string8][object][hingedbodygraphics]
0.61-export: <[string8][Name][RudderBullette]>
0.61-tmmodule: <[string8][RigidBody][Fuselage]>
0.61-export: <[string8][GeometryList][ RudderBullette ]>
0.61-tmmodule: <[uint32][PositionID][Fuselage.R]>
0.61-tmmodule: <[uint32][OrientationID][Fuselage.Q]>
0.61-export: <[tmvector3f][Axis][ -0.9962 -0.0000 0.0872 ]>
0.61-export: <[tmvector3f][Axis][ 0.0872 0.0000 0.9962 ]>
0.61-export: <[tmvector3f][Axis][ -0.0000 1.0000 0.0000 ]>
0.61-export: <[tmvector3f][Pivot][ -3.1649 -0.0001 0.4654 ]>
0.61-tmmodule: <[uint32][AngleID][ServoRightAileron.Position]>

** Note above, the TM log part block has the servo as [ServoRightAileron.Position]. That is changed to ServoRudder.
** Note also, the top string on that block says its a [hingedbodygraphics]. In this case, that is the proper animation type, so that is not edited.
Above, you see the three Axis (stack) are;
0.61-export: <[tmvector3f][Axis][ -0.9962 -0.0000 0.0872 ]>
0.61-export: <[tmvector3f][Axis][ 0.0872 0.0000 0.9962 ]>
0.61-export: <[tmvector3f][Axis][ -0.0000 1.0000 0.0000 ]>
So you could copy this block (above) and edit it to look proper, or you could copy/paste one from another plane (like the Robin, Cessna, etc) and paste it into your TMD, then edit it. Copy in the Axis strings (3) and the Pivot (Gizmo). Change the name of your model part (mine is RudderBullette), then save and check in Aerofly. If the rudder animates on the wrong axis, flip the stack for the next axis. Repeat test. Flip stack again for 3rd choice if needed.
Done... You now have a animated rudder. The missing component for me was the Servo control section.
You can run 'searches' for your parts concerning the Servo names.
Note also, in my case, that the animation block in the TM.log is given a common Servo name and animation name. Those will probably change to something else. There are several types of 'Graphics' names and Servo names. In my case, with the rudder, I am using [hingedbodygraphics], and its Servo is ServoRudder.
There are downloadable lists in the new Wiki where you can copy out the names of the parts you need, and they are in similar plane's 'TMD' files also.
Hope that helps people out.
