This is our new affordable 2500kv 10-pole non-sensored brushless motor. 1st in the industry! This non-sensored version is very durable and completely element proof. Beat it, bash it, under water/mud -- it doesn't care. Unbelievable battery efficiency will keep you on the trail longer. All wiring included, this guy is ready to bolt in! 2500kv version is for those who run 2-4s only and want the best in speed, crawling, and low end torque.
