Stoney, the two (FM and graphic model) are not completely related, as you can update the FM and not the graphics. However, as HTC is redoing the old models they are upgrading the raher buggy FMs to better FM standards. I would guess this includes more points on the wing where airflow is sampled. If you recall pics of the new Corsair stall patterns some time back, I think they go through all of that and produce a much more competent flight model than the old AH1 beta days could provide.
