John Scheinbergon Holmes Hobbies CrawlMaster Magnum 540 Brushed Electric Motor (20T)

There just isn't a better crawling motor. It's just bonkers smooth. After running a lot of motors in brushed/brushless/outrunner setups; this one is king. The stubby version for lighter weight. Running on castle or holmes esc with "holmes hold" enabled is essentially a locked drag brake; much stronger than other motors. Also the craftsmanship is on another level. John Holmes for the win.
