Castle 10th Scale 1406 Sensored Motor - 5700Kv (Includes free Motor Fan)

Product #: 060-0057-00

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.


When tasked with designing a sensored motor our engineers started with the question,

“What makes a motor great?”

  • Efficiency
    • You can push it harder (gear it up)
    • You can run it longer (with the same battery)
    • It stays cool under extreme loads
  • Reliability
    • Ability to withstand the harsh demands of any RC application
    • Long-life, high-quality components
    • Proven manufacturing techniques


The higher the efficiency of a motor the more power it can produce without overheating, which allows you to safely run higher gear ratios. The higher the efficiency of a motor, the less power it takes to produce the same output power, which allows you to run longer on a single charge. The higher the efficiency of the motor, the less energy it turns into heat; keeping it cool under extreme loads. Efficiency equals performance.


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. Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible. High-strength, high-temperature grade neodymium sintered magnets combined with a high-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions. Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, 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.

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. We recommend 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 this document for running and maintaining motors in wet environments.

Motor designed in Olathe, Kansas USA.
Motor Made in China.


  • Our IMPROVED 4-POLE 12-SLOT design boasts exceptional EFFICIENCY and produces LESS HEAT.
  • QUIETSENSE™ 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 Shield™ in conjunction with secondary Sense Magnets delivers even HIGHER PRECISION and MORE EFFICIENT startups.
  • Our OPTIMIZED design eliminates the need for mechanical timing adjustments. Our sensor alignment method delivers uniform timing and torque in both directions, automatically.
  • REBUILDABLE design allows users to replace front end bell/bearing assembly or rotor/shaft assembly.
  • ROAR standard sensor port and labeled connections.
  • Updated modern and sleek design; looks as cool as it performs.

Immense care is taken by our US design team during every step of the development process. While using the highest quality components is important, design is equally important. Our experienced, in-house engineering team, located in Olathe, Kansas, has spent countless hours simulating and developing the most efficient design. Development includes magnetic simulations, custom winding techniques, and rigorous, real-world testing of the final product.

 During a 5-minute constant power dyno test the results were clear. When producing 200W of power, our competitors’ motors increased in temperature over 20% more than the Castle 1406 Sensored motor. When producing 300W of power, it wasn’t even close, their temperature climbed at over twice the rate of the Castle motor and then overheated in around two minutes while the Castle motor powered through and completed the test. _Click here for graph_

* Competitors’ motors is average of several 7.5T 2-pole motors typically used in mod-style racing.

You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder.

We take OVERPOWERING seriously.


Castle engineers always add a little something extra in their designs that takes your performance to the next level. We have not skimped here. Many customers have utilized our industry leading software functionality that Castle Link* offers. When paired with a Castle Creations sensor supported ESC, like the MAMBA MICRO X, MAMBA MAX PRO or MAMBA MONSTER X, you can unlock advanced tuning capabilities that Castle Link provides specifically for sensored motors.

SMARTSENSE™ uses the motors sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability. Once the motor is turning, it seamlessly transitions to Castle’s ULTRA- EFFICIENT sensorless mode. When running, a motor must transition between different load points and a different timing advance is required for optimal efficiency at all load points. Using mechanical timing adjustments alone, you can only target one driving condition, such as higher start power or higher top end speed. This sacrifices performance and efficiency during the other driving phases. Electronic timing in SMARTSENSE™ will advance timing automatically for peak performance during all driving conditions. This allows users to combine the best of both worlds in an unrivaled HYBRID between smooth sensored startups and high-efficiency sensorless drive.

With a Castle sensored ESC and sensored motor you will have the ULTIMATE POWER PLANT for your vehicle. Users will experience PRECISE throttle control, BUTTERY SMOOTH starts, PEAK PERFORMANCE and EFFICIENCY throughout the full throttle range. You will feel the POWER and LONGER RUN TIMES that a WORLD-CLASS motor produces.

It’s not magic… it’s SMARTSENSE™.

Amazing motor
July 14, 2023
I have had this moror in multiple cars over the years and it hasn't failed me once. This motor has outlived the cars that it has been in. Now I have it paired with an copperhead esc in my drag slash and it sends it hard. Great acceleration and power throughout. Not to mention castle was the first brushless system I ever got and I still have the first motor I bought over 8 years ago and ut still runs great. You can't beat the price and reliability of a castle motor.

My now 6 year old son. Has this motor with the mamba max pro esc. I am enjoying watching him zip around the track. Keeping up and blowing by seasoned racers on the straight aways. (Practicing of course! He isn't racing yet, corners and air still needs time.) Also being able to change and tune so many variables with the esc to the motor is great. And being able to stay on the track and run and not over heat is the best. Who wants to have to stop becuase their running to hot. No one. Especially a 6 year old. Thanks castle. Any suggestions for the next motor to get? Once or if this one finnally sees its last run. As your stickers say powered by Castle. Which will always be on our RC's.

I race at a track thats pretty much run what you brung, They recently changed the configuration. While everyone else was scrambling for the right amount of turns. I just tamed the max amount of power on my esc till i found what worked! didnt even touch my gearing. it truly is like having 3 motors at your disposal. i dont even know how hard you would have to push one of these babies to burn it out.My temp is always far below that of other competitors Thanks Castle!
