Edited from ROTF Dune Runner, with guns removed (hinges are visible in robot mode just because it's easier to have them dangling on his shoulders than to edit them out.) This is, to me, one of the more obvious redecos. Get to it, Hasbro/Kitbashers! If I were to do this kind of custom, I'd keep at least one of those hinges (and remove the other completely) to give him some kind of satellite accessory, just so he has something to work with. Also, credit to Seibertron.com for the pictures. Enjoy!
