This is the Castle Creations Monster 2 1/8 (25V) Waterproof ESC Combo w/1515 V2 Motor (2200kV).

Castle Creations' introduction of the Mamba Monster was a break-through moment for R/C modelers wanting to experience what seemed to be unobtainable. Brute power and sheer stamina have made this our legacy "power up" for popular 1/8th scale buggies, truggies and on road vehicles and 1/10th scale monster trucks.

The Mamba Monster 2 ESC is capable of 2S LiPo to a maximum of 6S LiPo and is waterproof, which means you can run your vehicle through the morning dew, across the soggy snow or just about anywhere else you'd be interested in running a 1/8th scale RC buggy or truck.

The Mamba Monster 2 includes a coupon for a free Castle Link USB device. This allows access to the full programming suite of adjustable settings that tune and tweak your vehicle to your preferences, resulting in an incredible RC driving experience. This combo includes the Mamba Monster 2 controller and the recently updated Castle 1515-2200Kv V2 sensored motor (Sensored capabilities of the motor cannot be utilized with the Mamba Monster 2).
