The Mamba Monster X 8S ESC supports any RC vehicle weighing up to 25 lbs running up to 8S LiPo. It utilises Castle's CRYO-DRIVE™ technology, which reduces the rate at which the ESC heats up and removes heat more efficiently, allowing the setup to handle higher gear ratios in heavier vehicles with longer runs. An open housing design with a 40mm cooling fan and forged elliptical fin heatsink maximises airflow throughout the system.

Constructed around a robust aluminium casing with epoxy potting, the Mamba Monster X 8S is designed for all-weather use. Setup profiles can be created, saved and downloaded through the Castle Link Programming Suite on Windows, or wirelessly with the B-Link Bluetooth Adapter and Castle Link app for Android or iOS. Auxiliary wire on-the-fly adjustments allow access to parameters such as Torque Control, Max Brake and Rock Race Mode from your transmitter.

When paired with the 2028-800kv 4-pole 12-slot sensored motor, SmartSense™ mode uses the motor's sensors for smooth starts, excellent torque, and low-speed drivability, then seamlessly transitions to Castle's ultra-efficient sensorless mode. CRYO-DRIVE™ minimises the time the ESC's electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation.

• 1x Mamba Monster X 8S ESC
• 1x 4-Pole Sensored 2028-800kv Motor
• 1x Castle Decals
• 1x Instruction Manual

• High current battery connector rated for 120+ amps required — such as Castle CC Bullet 6.5mm, CC Bullet 8.0mm, or 6.5mm Polarised Castle Connectors, soldered to the battery leads

Although Mamba Monster X 8S is waterproof, it is not intended for operation while completely submerged in liquid. Always rinse the ESC with clean water after exposure to corrosives or dirt. The cooling fan must be removed before driving in wet conditions.

Applying voltages higher than 33.6V will cause irreparable damage to the ESC. DO NOT run HV cells (above 4.2V/cell) when running at max cell count (8S) — this will exceed the 33.6V rating and will damage the ESC.
