Ruddog 5-Slot Brushed Crawler Motors feature dual bearings, adjustable timing, plated end bells, replaceable motor brushes and springs, and brush heatsink towers. Plus, they are fully re-buildable if needed. The adjustable timing allows to adapt and optimize the motors for drive trains that require reverse motor rotation operation. The motors are available in a total of six different winding variants. The 5-slot configuration is recommended when you want smoother throttle response, while the 3-slot configurations offer more overall power.
