Nice work. The landing gear and working tail are nice upgrades to the Brickmania version. Not to stir the tile versus stud debate, but but lack of studs is more due to your use of bricks for wings rather tiling the plates. I'm working on build of Shoeless Joe's P-61 and would be done if not for all of the tiles. Don't let studs bother you, they are after all what makes Lego a Lego.
