So firstly I am working on the flight model right before I move into blender! But we had to take off the winglets because x-plane doesn't simulate vortexes so the winglets were just making unnessisary drag and on big turns it would act all funky... We also fixed the engine pylons because they were creating lift same with the horz stabizer because that was making to much negative lift! Been looking at the undercarriage it is mostly wrapped up so then the really indepth undercarriage in blender will still make the plane fly right in x-plane. With fixing the lift and winglets now the plane will get into its high speed during climb because before it was only goin in the 200s on the climb when passing FL140... So more news coming soon(and some big news)
