Hi Mike.
Wonky Spitfire MkIa? Well could be, because I think it was my second or third HR model, and that is like a looooooong time ago.
The problem with most of the so called HR models is they were adapted from the LR models, mostly by just hacking the model into bits, piggybacking lots of elements, and remapping. Back in those days, it was quite a challenge to get a model to work right, even in D3D, let alone Glide!
The trick with Glide, is not to use -32768 on any element, which is linked to a double sided element. Wing tips are a common nasties, and adding things like flaps, which are also double sided flat elements, can only add to the woes. The other problem is the number of elements in a standard wing model can be as few 30, which does not give you much of a chance of adding piggybacks, with a sure chance of success, especially for Glide.
The only real solution is to rebuild the wing in a more logical way, so things like flaps can be built in correctly.

Oh, and I totally agree with your comment, "This

Not this
