This is the Castle Creations Monster X 1/8 Brushless Combo w/1515 V2 Sensored Motor (2200Kv).

PUTTING THE X IN EXTREME!
Our Mamba Monster X ESC and 1515-2200Kv V2 are paired together and perform incredibly in monster trucks with up to 6S LiPo packs (4S LiPo is the sweet spot), and works great in 1:8 scale buggies, truggies and on-road vehicles as well as 1:10 scale monster trucks weighing up to 15 lbs. You will have all the power your 1:8th scale vehicle demands with the smoother throttle control of a sensored motor. Mamba Monster X takes Castle's legendary "monster" performance to a whole new level.

New 1515-2200Kv V2 motor now included! Our commitment to excellence drives us to refine the user experience, optimize performance, and ensure that every aspect of our products are meticulously designed to provide the utmost satisfaction. Let's face it, even the best products have room for refinement, which is why we are excited to introduce the newly redesigned 1515-2200Kv V2, a new spin on one of the most popular motors we've ever produced! The transformation has included several improvements, most contributed by new stator and rotor assembly upgrades that, in turn, allow for even HIGHER EFFICIENCY, REDUCED TEMPERATURES, AND SMOOTHER START-UPS!

MAMBA MONSTER X Features:
Input Voltage Range : 2s-6s LiPo (ESC Only)
SMARTSENSE™, SENSORED ONLY and BRUSHED Running Modes
Selectable 5.5V or 7.5V (6A peak) internal BEC (Battery Eliminator Circuit)
Auxiliary Wire Functionality allows for "on-the-fly" adjustments such as Max Power and Max Brake.
ESC is housed in a durable injection molded case and potted in WATERPROOF epoxy to protect the electronics and promote efficient heat transfer.
Removable 30mm fan
Compatible with S.BUS2 Telemetry Link and Futaba T4PX, T7PX and T7PXR transmitters
DATA LOGGING to capture and record performance data from your vehicle
AUDIBLE ALERTS for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff.
Convenient TRANSMITTER PROGRAMMING for six common adjustable settings inlcuding cutoff voltage and drag brake.
SMARTSENSE™ uses the motor's sensors at startup to provide cog-free starts, excellent torque and low-speed drivability. Once the motor is turning, the ESC seamlessly transitions to Castle's ultra-efficient sensorless mode.
CASTLE LINK USB programming kit (coupon included with purchase)
Optional smartphone-based programming with the B-LINK™ BLUETOOTH ADAPTER (sold separately) and Castle Link App available on Google Play or Apple App Store
