Holmes Hobbies CrawlMaster V3 Sensorless Brushless ESC Combo w/Revolver V3 540M Rock Crawling Motor (1800kV)

The Holmes Hobbies CrawlMaster V3 Sensorless Brushless ESC Combo with Revolver V3 540M Rock Crawling Motor combines a 32-bit CrawlMaster Mini V3 ESC with a Revolver V3 540M 1800kV brushless motor designed for 1/10 and smaller single-speed trail, scale, and rock crawlers, including the Traxxas® TRX-4™ Sport, Axial® SCX10™, Element® Enduro, Vanquish® VRD VS4-10™, and similar platforms. This combo works on 2S to 4S LiPo operation, while the complete set weighs just 145 grams, arrives ready to use without soldering or programming, and is recommended for vehicles up to approximately eight pounds depending on gearing, driving style, and terrain.

The CrawlMaster Mini V3 ESC uses 32-bit processing to support advanced control algorithms, including Holmes Hobbies' exclusive Sinewave Startup system for smooth motor engagement with broad motor compatibility. Intelligent RPM lock maintains precise low-speed control where crawling demands accuracy, while standard throttle behavior at higher speeds helps preserve torque control and reduce drivetrain stress. Silent operation with most motors, an internal 7.4-volt 3-amp BEC, conformal coating for water resistance, temperature and throttle-loss protection, and an included USB programmer round out the ESC's features. Paired with the lightweight Revolver V3 540M 1800kV motor, which features a V3 ultralight housing, chrome-plated magnets, a precision magnet retention assembly, Holmes-designed magnetics, and a standard 1/8-inch shaft output, the combo delivers a compact package developed for competitive crawling rigs as well as scale and trail vehicles that benefit from a smaller, lighter motor.
