I finally updated both jumpstarters! Here are their vehicle modes. I used Movie Air Raid for Topspin. I just painted him up in his G1 colors. I just found Universe Scattershot at KB Toys and used him for Twintwist. I also found a knock off constructicon set and used the missles for Twintwist's drills. As for Twintwist, when I mistransformed him, I found a mode that makes him look better. He even serves as a launch pad for Topspin.
