I will switch to P3D from FSX(i am going to use the V3, 4 is too dope for my computer, i could try it tho), i want to know if the BAe ATP made by Enigma Simulations will work there? --- Post updated --- This is the ATP
Transfering addons between sims like this can be a bit iffy. It has been done just fine with stock FSX aircraft, but with external paid/Freeware aircraft can be problematic. it all just depends on the aircraft, sometimes it will transfer 100% fine and other times it won't even appear. Considering this looks to be a freeware aircraft that is extremely old and you are using V3 instead of V4, I would guess it has a good chance of working. If it doesn't I'm sure there is one for P3D that will work
I searched one for P3D, and no, i didn't find a proper P3D version, the ATP i talk about is for FS2004(extremely old), but a lot of repaints were made for FSX, so i guess it'll work.
