not a lot of options as far as a chassis for a juggy. check RC4wd.com. I'd pick one that gives good articulation and a low center of gravity. After that lock the front and rear diffs, set up 4ws, leave all sway bars off, gear it with the smallest pinions you can put on there with Kyosho Magnetic meyhams, and soften up the suspension and crawl. I have a Clod crawler myself which is different than a juggy which has a center mounted trany and motors vs. the clod with its axle mounted tranny's and motors.
