Hi all,
Great mods, I finally finished mine, please let me know your thoughts. This was my first star wars set and my first attempt at mods. It is almost all Lego but the grey engine grille piece is Mega Construx (from harrier set).
I added in the usual interior mods, ladder, gun rack, toilet. Made the landing gear fold flat, modified engines added slopes to underside of wings and filed gaps at tail section. Also modified the cannons to look more like on show especially the side fins on them, and I built up the intakes/flat pieces on underside of engines to look more like show. The underside was probably the trickiest part for me to design, good old trial and error.
