Drivers in all applications demand clean starts when coming off the line. Crawler fans require high-precision low speed control and torque for climbing, racers need precision and predictability, and dragsters don't have a millisecond to spare. To achieve all of these performance demands and more, we have integrated rotor position sensor technology with our improved high power and high efficiency motor design. Through the use of our sensors, the position of the rotor is always known by the ESC. This eliminates the possibility of encountering cogging or inconsistency during startup. Users will experience PRECISE throttle control and BUTTERY SMOOTH starts plus the RAW POWER and LONGER RUN TIMES that our highly efficient motors produce. In the end, the result is a motor with unmatched quality, performance, and reliability. We wouldn't put our name on anything less. The 1717-1260Kv is the perfect upgrade for any 1/6th scale vehicles weighing up to 20 lbs and running up to 8s LiPo; it is also a great upgrade for drivers looking for a reliable, high torque 8s motor for their 1/8th scale vehicles. NOTE: The 1717-1260kv has a lower wattage/power rating compared to the 1717-1650kv; as such the 1260kv will run hotter than the 1650kv when geared for the same speed. For higher power applications (IE speed and drag setup), the 1717-1650kv is preferred with appropriate gearing.
