This is my first Monster Truck in a few years, this started life as a used E-Maxx 3903 model that was missing some parts. I completely went through everything installing new bearings and re greasing everything and replaceing what was worn out or broken. I also installed the single motor mount and cover kit, Traxxas center steel CVD driveshafts, Traxxas Big Bore aluminum shocks, 17mm hub kit, Pro-Line Trencher X's on 1/2" offset Desperado Wheels, Pro-Line Super Duty body, upgraded the slipper, 68t spur, 18t Robinson pinion, Team-C 1900kv motor, Hobby Wing 150amp ESC and my Futaba 4pl radio. I've been running it on 6s and it's a beast! My build isn't anything to crazy, it's just a fun Monster Truck.
