With 15" tires rotating and major torque being applied at all times.. Recently installed a new motor and power distribution block, I was eager to get into my back woods area to test the truck in the mud. I reviewed the truck over and over.. and got some great shots out on the trail. Mud, Muck, Rocks, and a few amazing slow motion action shots - and then back to the drawing board, but that is half the fun for me! I enjoy washing the truck off also, as demonstrated in the video near the end. Enjoy.. this truck is one of a kind, but based off of a Primal RC mega truck. Primal RC is the manufacturer, and I do not work for them. I am a Radio Control hobby enthusiast that has built a crazy awesome offroad machine. More to come!
