Features: ESC: Input Voltage Range 2S-8S LiPo Sensorless, Sensored and SmartSense™ Running Modes Powerful Integrated 8A Peak Adjustable BEC (5.25V-8.0V) CRYO-DRIVE™ Technology minimizes the amount of time the ESC’s electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation where the majority of driving occurs ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and promote efficient heat transfer Premium forged heatsink with elliptical fins for superior air flow and increased heat dissipation Oversized factory equipped thermally controlled 40MM cooling fan Compatible with S.BUS2 Telemetry Link and Futaba T4PX and T7PX transmitters Waterproof design for all weather conditions Data logging capability to capture and record performance data from your vehicle Auxiliary wire functionality for "on-the-fly" adjustments using your transmitter 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 including cutoff voltage and drag brake Easily tune and update ESC with USB and Bluetooth™ programming options 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 Proudly designed and manufactured in Olathe, KS USA and backed by Castle Creations' 1-year warranty Motor: The 2028 Extreme can easily run in the 10 horsepower range (Burst power output for duration's typical of vehicle acceleration.) Running modes include Sensored and an ULTRA-EFFICIENT sensorless mode. High-strength, high-temperature grade neodymium sintered magnets combined with High-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions. Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible. Proprietary winding techniques allow Castle Creations to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor. Dual sensor ports to ensure optimal installation in your large-scale vehicle. Updated modern and sleek design that looks as cool as it performs.
