The 4.1 update is a game changer in terms of fps (no more low fps as with pre-v4 version). It is a solid aircraft reflecting well its real life counterpart. A definite part of my virtual hangar. The devs are also actively working on the title (check the update history) unlike some other devs, which deserves recognition on its own.
3D modelling seems to be ported over from P3D and is fine. The ground textures suffer from obvious tiling all over the airport (including runway) and there are also some ugly low res textures on aprons and on the runway. All in all, the ground texturing is far below the usual freeware content quality in my opinion. There is also other issues (elevation, night texturing, incorrect runway profile, out of date taxiways...) but the ground texturing is really killing this product for me. This review is relevant for the initial release.
