Racer Bob said that the 5700 was too slow and the 7700 was too fast, so we’ve introduced the 6900 and it’s just right! Castle is pleased to announce the newest addition to the mind blowing CM36 series of brushless motors which are the perfect compliment for the awesome Mamba Max controllers. The 6900 packs lots of punch on 6 NiCad/NiMh cells and is incredible on 2S lipo, yet the 1/10th scale car, truck or buggy will still be (almost) controllable, unlike the 7700 which simply overpowers everything. This motor is best compared to a 6T brushed motor on steroids, with none of the brushes or comms to ever wear out. These motors are all built to the highest specifications and feature high torque Neo magnets and oversize lifetime bearings with a hardened steel shaft turned down to a 1/8” pinion shaft.
