The Castle Creations 1717 Sensored 4-Pole Brushless Motor (1650Kv) provides the best of both worlds - a nostalgic design with the latest sensored technology! Boasting a 4-POLE 12-SLOT design, this motor offers impressive efficiency and less heat compared to similar models. It's an ideal choice for 1/6th scale models weighing up to 20 lbs and running up to 8s LiPo. And for those in search of a high torque 8s motor for 1/8th scale models, the 1717 is a perfect upgrade! With a robust and reliable design, this motor can withstand even the toughest conditions, resulting in a cooler running motor with a longer lifespan. The motor's components were carefully selected and tested for the highest efficiency possible, resulting in a product with unrivaled quality, performance, and reliability. Take your RC experience to the next level with the Castle Creations 1717!

Features:

• 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.
• Proprietary winding techniques 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.
• IMPROVED 4-POLE 12-SLOT design boasts exceptional EFFICIENCY and produces LESS HEAT.
• QUIETSENSEâ„¢ technology shields the sensors from magnetic field noise generated from the motor coils and keeps your motor and ESC in sync at all times. Use of a Flux Shieldâ„¢ in conjunction with secondary Sense Magnets delivers even HIGHER PRECISION and MORE EFFICIENT startups.
• OPTIMIZED design eliminates the need for mechanical timing adjustments. Sensor alignment method delivers uniform timing and torque in both directions, automatically.

Product Use Statements: Monitor motor temperatures closely; overheating a motor will cause permanent damage to the magnets. Never exceed 180° F on the the motor or ESC.

Application Guidelines: The 1717-1650Kv is a water resistant design. The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommends applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to the owners manual for running and maintaining motors in wet environments.
