The Blackfoot chassis is the first evolution of the ORV/Frog chassis. Tha chassis is now used as a basis for a Monster Truck. The main changes are redesigned front suspension, now with much better travel/damping and a new radio system cover. The rear suspension and drivetrain are in practical terms the same as the ORV. The Blackfoot and Monster Beetle, both using the Blackfoot chassis, were re-released in 2015/2016 with sone changes to the drvetrain.
