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! It 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.

• 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.
