my buddy made it,looks simple,somewhere he found the specs on a hpisavageforum page.
beleive it or not but at the end of the day one revo not pictured broke-the roll cage hit and broke the front clip screw,not a big deal.
1 savage threw a dogbone and my xxl dropped a toe link,so the 2 savages broke while only one revo took damage.i have both and like both.the savage is just pure brute,ignorant torque,but dont handle like the revos
