The Castle 1520-1650KV motor is a 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 for 1/8, 1/7 and 1/6 scale vehicles weighing up to 18lbs and up to 8s LiPo. The 1520-1650Kv has all of the secret sauce that the big brother 1717-1650Kv has, but in a more compact diameter, fitting into smaller spaces without modifications to your chassis.

Vehicle examples include Losi LST2-E; Arrma: Limitless, Typhon 6s, Kraton 6s, Kraton EXB, Infraction Felony 6s, Notorious 6s, Talion 6s; Kyosho Inferno, Traxxas: E-Maxx, E-Revo, UDR, Summit; Redcat Shredder Note: "Recommendations based on vehicle weight and motor capabilities. Verify motor fitment, may require optional motor mount."

• Running modes include SmartSense™ 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
