Reedy's Crawler 16T 5-slot motor is the same motor that comes standard in the Element Enduro Trail Truck, Sendero RTR. But it is far more than a typical RTR motor thanks to its 5-slot design, which allows for precision control on a variety of surfaces and course conditions. Long-wearing brushes, fixed 0-degree timing, low-friction bushings, and silicone lead wires make this the best bang for your buck performance upgrade for your truck.
