I remember some Yasim additions in the past that weren't persued anymore (e.g. work on the gear-Ground interaction, or more recent, the propeller feathering feature, which I would highly appreciate). > So, I'm more than happy to apply patches *providing* I can be convinced they > are sane+reasonable from a pure code perspective (happy to help with that, > too, if people are new to C++), and providing we have some assurance that a > representative sample of yasim aircraft are unchanged or improved by the > patch. Suggestions for that means in practice, are most welcome! I'm afraid I can't comment on the C++ side, the only thing I can do is test the additions afterwards, or try to apply the patches. > Otherwise I worry, given the nature of the solver, we'll keep optimising the > solver for some aircraft, and making other existing aircraft worse - until > someone tests them, and announced that they're no longer working. Well I think the solver does quite well in most cases, there are some features I like to have, like a means to adjust the propwash effect on the control surfaces, or the gain of stick forces with increasing speed and the aforementioned Propeller feathering. > James
