Crawlmaster HV Brushless Crawler ESC 

The CrawlMaster HV is a new ESC designed for the needs of RC Rock Crawlers! The HV design offers larger mosfets for stable use on 4s with higher KV motors, as well as 6s cabablity for 1000kv motors. It harnesses the power of 32 bit technology to offer the smooth, quiet, and torque dense driving you desire in an extra small package!

These are NOT WATERPROOFED. We recommend coating with silicon conformal if you plan to run in wet, moist, or dusty environments. 

Instructions: crawlmaster-mini-v2-instructions.pdf 

RECOMMENDED USE:

• 1/10th and smaller Single speed Trail, Scale, and Rock Crawlers such as TRX4 Sport, SCX10, Element Enduro, etc..  
• Recommended 8lb limit, subject to gearing, driving style, terrain, etc.   
• NOT recommended for two speed vehicles, rock racers, tow rigs, and other high load installations.  

FEATURES:

• 32 bit processing power unlocks advanced control algorithms and future upgrades
• Exclusive Sinewave Startup (like FOC) but open system and compatible with all motors 
• Silent operation with most motors, inaudible switching frequency
• Intelligent RPM lock at low speed for unmatched control when it matters most
• Normal "PWM" throttle above startup for predictable power output and less broken parts
• No on/off switch to fail. Plug it in and go! 
• Overcurrent, temperature, stalled rotor, and throttle loss protection
• Automatic cell detection and low voltage protection for LiPo battery
• Ultra smooth throttle and strongest drag brake out of the box
• 5 volt 2.5 amp internal BEC

SPECS

• 2 to 6s lipo (30v max)
• "120 amp" package, 40a continuous operation
• Dimensions: 38 x 27 x 4.6 mm (PCB board)
• Weight: 32g assembled

INCLUDES

• Complete ESC
• 100mm (approximate) motor leads
• 100mm (approximate) XT60 battery lead with integrated JST connection
• 125mm Rx lead
