Crawlmaster Mini v2 ESC - RTR with XT60 connector

The CrawlMaster Mini ESC is a new ESC designed for the needs of RC Rock Crawlers! The v2 design adds an internal BEC and larger mosfets for stable use on 4s with higher KV 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! The ESC has been fully soldered and waterproofed by Dlux Fab.
