About this part
ESC & Motor Combo Overview:
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.
About the Brushless Combo
Purpose-Built Crawling Performance
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.

GREAT COMBO I WILL DO THIS AGAIN tHIS THING WILL SIT ON A ROCK ALMOST STREIGHT UP AND DOWN
My first HH setup and so far this is a beast in a VRD Carbon with a stubby kit. No complaints at all. Strong, quiet and pulls well.
A awesome motor and esc. It’s the smoothest I’ve used on start up
Just AMAZING!!! It’s an absolute pleasure to do business with everyone there and all of the products you folks provide for the Rc hobbies enthusiasts. Shipping has been excellent as well and all the updates with the emails also keep up all of the excellent work!
Great price for the combo. Good quality and fast shipping.
All eight reviewers are verified owners who rated the combo 5/5. Reviewers consistently praise its torque, strong low-speed control, smooth throttle start-up and quiet operation. It is described as well suited to lightweight rock crawlers, including VRD Carbon and Mullet builds, with one reviewer noting it is perfect on a VRD Carbon. Reviewers also mention a good price, fast shipping and plug-and-play setup. One reviewer using a Trailfinder 2 reported smoking the slipper pad on the first run due to the punch, and recommended a slipper eliminator. Another reviewer preferred a higher KV for more wheel speed in an Optic build, while noting 1800kV works. Overall the reviews are uniformly positive with no contradictory reports, though the sample is small and mostly from the same brand-focused audience.
- + Strong torque and low-speed control
- + Smooth throttle start-up
- + Quiet operation
- + Good value and fast shipping
- − Can overwhelm drivetrain: slipper pad smoked on Trailfinder 2 without slipper eliminator
- − Higher KV preferred by one reviewer for Optic build
