I know this has been done before but I've wanted to do it to mine for a long time.
I repainted this guy over a year ago, before I used good paints or had decent brushes, or even did much other than painting toys. That's why you can see a bit of streaky on the paint job except the new arms I gave him and painted just yesterday.
I have a Universe Jetfire and Treadbolt but I wanted to be different so I used BW Depthcharge arms and a wire from a cel phone charger. The Depthcahrge arms make it possible to switch his hands into a drill/booster/whatever although the left arm doesn't switch now due to the gun extension I added.
In Alt mode I don't know if I like the rear arm up as a second weapon/radar/whatever or back and down as a booster/drill tool/whatever.
I kept the green on his chest and eye because I like it despite taking from the G1 accuracy a bit. Screw it. Its for me, not to sell right?
