So wanted to response with a couple quick things.
First, make sure any bug/issues are reported in the Bug Report thread that is a sticky. I spent quite a couple hours last night cataloging all the reports bugs from there along with the requests so we can analyze them, replicate them, and correct them. Just makes it easy to have things there, otherwise I might miss an issue like this since I have tons of threads to reply to.
Second, is about the flight model. You bring up a valid concern. So in order to get the correct answer for this, I need to contact our primary coder who created the flight model. Along with him, we also have several real world Gazelle pilots who, along with flying the SA-342M, are currently deployed in various military forces. Some of them are easier to reach then others. But they were a great resource for us for getting this far, and we'll defer to them for any possible modifications to the FM.
So while I'd love to give you an answer now, I'd rather give you a correct answer and it takes time to get that. So know were working on it.
