Holmes Hobbies CrawlMaster HV 1/10 Rock Crawler Sensorless Brushless ESC (2-6S)

The Holmes Hobbies CrawlMaster HV is a sensorless brushless ESC for 1/10 single-speed rock crawlers up to 8lbs. It supports 2 to 6S LiPo input voltage, with a 30V maximum, and delivers smooth control through Exclusive Sinewave Startup, Intelligent RPM lock at low speed, and Normal PWM throttle operation.

Its compact, lightweight design includes 32-bit processing, silent operation with an inaudible switching frequency, and protection against overcurrent, temperature, and throttle loss. The internal 5V 2.5A BEC powers servos, while automatic cell detection and low voltage protection support the power system.
