RE: Roll Cages
LOL Sounds like someone spends too much time shiny down [&o]
I know, you just want to protect stuff.
They make them for other RC's. Do a google search for Hard Bodyz roll cage. Or just search rc roll cage. I saw some pretty interesting ones out there. If you can braze, you could fab one up using some automotive 1/4" brake line with tabs brazed on the ends for feet.
Hope this helps some.
