Still cool with plenty of power to spare!

The 1717-1650 is truly a blast from the past and the first new 17 Series release in over a decade and our second combo offering for the Mamba Monster X 8S. Higher torque and lower RPM than the 15XX Series, the 1717-1650Kv is a perfect upgrade for heavier 1:8th vehicles and lighter 1:6th vehicles (up to 20 lbs) running up to 8S.

The Castle 1717 1650KV motor now has an IMPROVED 4-POLE 12-SLOT design that boasts exceptional EFFICIENCY and produces LESS HEAT.  This motor is a blast from the past with the added benefit of sensored capabilities!

• Running modes include Sensored and an ULTRA-EFFICIENT sensorless mode.

• High-strength, high-temperature grade neodymium sintered magnets combined with High-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions.

• Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible.

• Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor.

• Updated modern and sleek design; looks as cool as it performs.

Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it, resulting in a cooler running motor. A cooler motor has a longer lifetime. Construction of our motor required careful component selection; each verified through internal testing to ensure the HIGHEST EFFICIENCY possible. In the end, the result is a motor with unmatched quality, performance, and reliability. We wouldn’t put our name on anything less.
