Holmes Hobbies CrawlMaster HV 1/10 Rock Crawler Sensorless Brushless ESC (2-6S)
About this part
ESC Overview:
The Holmes Hobbies CrawlMaster HV Brushless ESC is specifically designed for lightweight Competition RC rock crawlers, one-tenth scale and smaller single-speed trail and rock crawlers, such as the TRX4 Sport, SCX10, and Element Enduro to offer exceptional buttery smooth performance for trail, scale, and rock crawling applications. This advanced electronic speed control is capable of handling voltages up to 30v while ensuring stability with higher KV motors. With its compact design and powerful features, it provides a smooth and quiet driving experience essential for tackling challenging terrains with confidence and ease!
The CrawlMaster HV ESC features a lightweight and compact design, making it easy to install in tight spaces. Its Exclusive Sinewave Startup ensures smooth motor operation, while the silent operation with an inaudible switching frequency provides a quiet, precise driving experience. Additionally, the Normal PWM throttle delivers predictable power output, and the Intelligent RPM lock at low speeds offers unmatched control, allowing you to navigate tough obstacles with ease.
Note:
- NOT recommended for two speed vehicles, rock racers, tow rigs, and other high load installations.
- NOT recommended for vehicles heavier than 8lb.
- NOT WATERPROOF! Holmes Hobbies recommends coating with silicon conformal if you plan to running in wet, moist, or dusty conditions.

Great esc BUT you must run an external BEC for any servos to work. The built in the doesn't have enough power.
Great ESC at a good price and fast shipping. Holmes makes some of the better electronics around, and are worth the money.
Following a brief period of ownership, this unit experienced a malfunction, exhibiting erratic behavior at 75% throttle. I will be pursuing a Hobbywing product as a replacement.
I bought this for my 1/10 scale crawler and so far no complaints. Has a nice and smooth slow crawl and plenty of power when needed. I’m running an external BEC due to the limited power the ESC provides. I wouldn’t think twice to purchase another one for another rig.
Reviewers generally praise the CrawlMaster HV ESC for smooth slow crawling, adequate power, and value for price. Two of four reviewers (both verified owners) mention that the built-in BEC lacks enough output for servos, and both used an external BEC instead. One reviewer reported a malfunction with erratic behaviour at 75% throttle after a short period of use and planned to switch brands. Overall sentiment is positive, but the sample is small and the single reported failure is not confirmed as typical.
- + Smooth slow crawling
- + Adequate power when needed
- + Good value for price
- + Fast shipping
- − Built-in BEC insufficient for servos
- − Requires external BEC
- − Reported erratic behaviour at 75% throttle
