5 of 5 Simply the BEST Brushed Crawler Motor! June 14, 2019
Reviewer: Carmine Allocca from Tucson, AZ United States  
No, I don't work for them! But I have had extensive experience with Holmes Hobbies and other Good Brand Brushed Motors, in pretty Heavy RC Crawlers. My fattest being my 14.6lb Wraith - which this moves around (and UP), without breaking a sweat!!
There are a few good Brushed Motors out there. If longevity and durability are issues that concern you...
THIS would be the clear winner! It is also VERY Strong, and includes all high quality components.

Seriously.... If they had THESE back in the Clodbuster Truck Pulling days - we'd be destroying a lot of Gearboxes!!  :O
