Really good simulator ! the best one out for sure, softbody physics are really well done and how the sim supports dynamic wind and thermals is really cool ! I really love it !
I think a "repair wing" button would be a good feature to add, in order to put the wing back to normal when it's upside down after collapsing for instance. Idk if it's an easy thing to implement tho :)
keep up this awesome work !
