Started with Wheeljack as the base, I soon added some new wings and to continue Prime’s style, I had a jetpack for Tracks that can work in either car or robot mode. New head that better resembles Tracks, and finally added a new weapon. He has been completely repainted into a nice metallic colors. Of course Tracks can’t really be Tracks without his trademark flames on the hood. Made custom made decal to go along with him.
