My brother has that rig...and holy cow does it move! We used a GPS on it and stock gearing out the box on 6s...EASILY was in the 60mph range. It has a very low CG and chassis, so you wanna ensure you have smooth large surface for running it and ensure you buy some extra tires...you can do burn outs and donuts for days! One of Arrmas better built rigs for sure.I’ve got a soft spot to buy one of these....
