13t CrawlMaster Pro.
 

While still very new to this side of the hobby I recently swapped my basically new (less then 4000mah's thru it) ROC412 3100 out for a HH CM 13t.
Wow I'm hooked, more then enough wheel speed geared 11/56.
The motor seems to stay comfortably cool, it never went over 125° in 85° ambient temps.
Lastly the slow speed control, being a newbie perhaps I was having trouble with throttle control on the ROC, the more I practiced the better I got.
That said the CM is a dream for low end control and for me just a much smoother motor all around.
Perhaps one day as I become more familiar with scaling and the art that is crawling, I will once again try the ROC412.
For now and the near future however the CrawlMaster will remain in my scx10.
Thank you for such a great motor John."thumbsup"
