So put the (visual) model origin at or near the CofG - what's the problem?
Seems to work OK in practice.

I remain disconcerted that the visual model appears to roll through 180 degs
vertically on the up and down legs of a loop when in chase or helicopter
view. Not the end of the world, but lacking realism.

nd, the
contribution of both is marginal, I feel. I would be surprised if the
radiator drag, or lack of it effected the overall behaviour of the P51d
model. I think there is something bigger at work here - an incorrect entry
in the Yasim file, or an FDM error. I suspect something to do with the
propeller right now.

Look in the Hunter or p51d model files to see how it can be done.
