Hi
I've created a fork that fixes some annoyances in the visualisation (for me at least - they may not be annoying to others)
It's here:
https://github.com/enrogue/simple_yasim_import-gitthere are 2 branches at the moment:
slats-spoilers - put slats on the leading edge of the flight surfaces, and spoilers just behind the halfway point
moving-surface-size - the above plus making the slats/spoilers/flaps and eighth of the chord width - so they taper with the wing
I'm not a Python programmer - this is probably my first look at Python - in fact I'm a very rusty programmer all round, so apologies if it lacks efficiency (or just plain sucks)
I've tested it on 2.69 on Linux & 2.76b on Mac - no errors so far
If people think it's useful I could ask for it to be merged into main repo
