NOTE: A Mamba Monster X 8S service advisory has been released - please read this statement from Castle Creations. Castle has put a temporary hold on using D-Wind type and motors with Kv higher than 2,000Kv. A software update to correct this is coming in the next few weeks.

The Castle Creations Mamba Monster X 8S ESC/Motor Combo with 1520-1650Kv Sensored Motor is a great way to add some of Castle's secret sauce to your build. This motor and ESC combo is designed for 1/6, 1/7 and 1/8 scale vehicles running up to 8S batteries and weighing up to 18 lbs. If you have been looking for the ultimate combo to propel your rig without sacrificing power, punch, or speed - this is an ideal option. The 1520-1650Kv has all of the same features as its big brother 1717-1650Kv has, but in a more compact diameter. This allows use in a wider variety of models, without modifications to your chassis.

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.

The ESC was designed with a robust aluminum casing, and the epoxy potting guarantees protection around the circuitry and ensures all-weather use. Mamba Monster X 8S is a beast, ready to take on the harshest of environments and still perform. You can easily optimize the ESC for any driving condition, from rugged terrain to smooth pavement to the perils of rock and gravel. Create, save and download setup profiles through the Castle Link Programming Suite on your Windows PC, or wirelessly with the convenience of the B-Link Bluetooth Adapter and Castle Link app for Android or iOS.

When paired with the Castle sensored 1520-1650KV motor, users will experience controllable low-end control without sacrificing power, punch or speed. SmartSense mode uses the motor’s sensors to start the rotation, delivering smooth starts, excellent torque, and low-speed drivability. Once the motor is spinning, it seamlessly transitions to Castle’s ultra-efficient sensorless mode. You’ll put more power to the ground, where it should be, instead of wasting it through raw heat and RPMs.
