I'm having a guess Tracks has been done quite a bit, but this is my version I recently finished. I really enjoyed doing this figure, great fun! A Universe/Classics Sunstreaker was used. A new head, Excellion (I think ) that sits on a ball joint. I used Energon Megatron's weapons. I intended painting them white, but liked the black so stuck with them. High quality enamel paints used. A couple different metallic blues mainly. Varnished very carefully at the end, and Transforms very smoothly. I have two sets of wings that are both finished, but haven't decided on what ones to use yet!
