• Onboard data logging can monitor current, voltage temperatures, RPM and more. Download and analyze the collected data via Castle Link and make adjustments to maximize both performance and battery life..
• Mamba Monster X 8S features the addition of a programmable AUX wire that allows you to make “on-the-go” adjustments to several settings such as torque control, and max throttle, and fine-tune the performance of your ESC right from the transmitter using an auxiliary channel on the receiver..
• Redeem the coupon for the Castle Link adapter included with your Mamba Monster X 8S purchase and download the simple to install software on your Windows PC from our website and you are ready to personalize your controller's settings, or wirelessly program your ESC with the free Castle Link Mobile App and the purchase the B-Link Bluetooth Adapter (sold separately)..

Drive fearlessly and punch that throttle! Take your scale build or upgrade to the next level with Castle’s legendary brushless power. The MAMBA MONSTER X 8S W/1717-1650kv SENSORED COMBO is a perfect upgrade for heavier 1/8 scale vehicles and lighter 1/6 scale vehicles weighing up to 20 lbs. and running up to 8S LiPo. SmartSense™ mode uses the motor’s sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability. You’ll put more power to the ground, where it should be, instead of wasting it through raw heat and RPMs. The 4-pole 12-slot 1717-1650kv motor design boast exceptional efficiency, and the 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. You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder. The MAMBA MONSTER X 8S utilizes Castle’s breakthrough technology CRYO-DRIVE™. By reducing the rate at which the ESC heats up and removing heat more efficiently, your setup will be able to handle higher gear ratios, in heavier vehicles, with longer runs. These software advancements work in parallel with a unique open housing design to allow increased directional airflow to cool critical components. With the integration of a 40mm cooling fan and a forged elliptical fin heatsink, the design maximizes airflow throughout the system, taking thermal performance to a whole new level. High-performance demands high quality and this ESC was designed with durability in mind. Constructed around a robust aluminum casing, the epoxy potting guarantees protection around the circuitry and ensures all-weather use. Mamba Monster X 8S is a workhorse, it will dominate in the harshest of environments.
