CSE060-0091-00, Castle Creations 1721 Sensored Speed Run & Drag Race Brushless Motor (2400kV) The Castle Creations 1721 - 2400Kv Sensored Speed Run & Drag Race Brushless Motor was developed for experienced enthusiasts that are ready to take their extreme speed run and large scale drag racing setups to the next level. Ideal for running up to 8s LiPo in 1:8 and 1:7 scale vehicles, the 1721 features a mechanical design that boasts a stainless-steel sleeve to reinforce and strengthen the rotor for high RPM operation. Combine this with a massive 8mm stainless steel motor shaft, 8.0mm bullets and high strand, low resistance, silicone coated 8 gauge copper wire, and the 1721-2400Kv will deliver massive power and maximum top end speed. NOTE: Please read all product use statements and disclaimers, as well as the usage warning located in the resources tab before purchasing and installing this motor. !!!WARNING!!! Drag and speed run setups are inherently abusive and extremely hard on all electronic components. Every component in the configuration can be strained, weakened (or worse) without using extreme caution, observance of electric theory and advanced knowledge of all aspects of the RC hobby. High speed runs and drag racing are the most advanced, aggressive and volatile applications in the RC car hobby. Use of this product can result in catastrophic failures of the motor, ESC and/or batteries, as well as complete failure of the model, and potential damage to your surroundings. Important product use information is outlined below; following these guidelines will reduce the chances of failure but will not eliminate all risk. If you have any questions, contact Castle Creations customer service to help you get the most (as safely as possible) from your setup. Warranty: Castle products are backed by the industry's best service and support. This motor is balanced and tested during manufacture and is warranted free from defects in materials and workmanship for 30 days following the original date of purchase. Due to the abusive nature of drag and speed run setups, Castle and AMain Hobbies are not liable for incidental or consequential damages to any equipment, including but not limited to ESCs and batteries, when using this motor and are not responsible for failures resulting from abuse, improper installation or setup, misapplication or alteration. Product Use Statements: This is an extremely powerful motor designed for advanced and experienced users only. Below are suggestions for increasing your likelihood of success but it is not guaranteed. This is a VERY high RPM motor. Start with very conservative gearing (small pinion/large spur). Check your data logs, temperatures and setup closely after each run to ensure you are not stressing components. This motor is intended for single passes only; allow time between runs for the ESC, batteries and motor to cool down to ambient temperatures. This motor can pull very high amperages. Make sure your batteries, connectors and soldering are capable of handling the loads. Inadequate power can cause poor performance and damage the batteries and/or ESC. Do NOT free rev the motor with no load, particularly when running 6s or higher. The RPM output of the motor is much higher with no load as the kv and battery voltages do not drop. Set ESC timing to Lowest (0). This motor will pull considerably more amperage as you increase timing. This does not necessarily equate to more speed as it puts more strain on the batteries and causes the voltage to sag. Less is more sometimes. Do not exceed 33.6v when using this motor. Be sure your pinion and motor bullets are secure before and after each run. Specifications: Input Voltage Range: Min: 4s LiPo/Max: 8s LiPo (33.6V) Kv: 2400 Max.

Castle Creations 1415 1Y Sensored 4-Pole Brushless Motors combine rotor position sensor technology with an improved high power and high efficiency motor design to deliver ultra smooth startup, precise low speed control, predictable power delivery, incredible torque, and lightning fast response in your 2wd or 4wd short course truck. Through the use of Castle's Smart Sense technology, the position of the rotor is always known by the ESC. This eliminates the possibility of encountering cogging or inconsistency during startup, and allows the 1415 to deliver PRECISE throttle control and BUTTERY SMOOTH starts - with the RAW POWER and LONGER RUN TIMES that Castle motors are known forEFFICIENCY IS KEYThe 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.RELIABILITY CAN’T BE IGNOREDWithout a robust and reliable design, efficiency will only go so far. 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. Proprietary winding techniques allow Castle 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 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.INTEGRATED SOPHISTICATIONCastle engineers always add a little something extra in their designs that takes your performance to the next level. 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. With a Castle sensored ESC and sensored motor you will have the ULTIMATE POWER PLANT for your vehicle.SMARTSENSE™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.  Features: 4-POLE 12-SLOT design boasts exceptional EFFICIENCY and produces LESS HEAT Oversized gold plated solder tabs for LESS RESISTANCE and easy soldering QUIETSENSE™ Technology shields magnetic field noise generated from the motor coils and keeps motor and ESC in sync at all times 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 REBUILDABLE design allows users to replace front end bell with bearings or rotors with shaft ROAR standard sensor port and labeled connections High strength 180°C neodymium sintered magnets High quality, temperature-stabilized sensors High-purity, high-temperature copper windings Hardened stainless steel shaft 13 AWG high strand wire with silicone insulation Kevlar wrapped rotor 6061-T6 Billet aluminum heatsink can High RPM NMB oversized bearings High quality 0.2mm steel laminations Low resistance gold plated bullet connectors   Specifications:Input Voltage Range: 3-4S LiPoKv: 2400Max.
