I use almost solely these motors for my 1/10 scale crawlers, SCX10s and Wraiths. For an SCX10 this bolts on directly, and with a Wraith you need to dremel just a tiny bit from the back-right-upper suspension link post to make room. These things have a TON of torque and a good amount of speed. They also last a good while. I use 14t pinion and 87t spur on my 3,5 kg Wraith with a 4S lipo battery. The thing goes like crazy! Same thing with my SCX10, altough I use only 3S batteries with it. Combine this with Holmes Hobbies BRXL (up to 6S input!) and you have the smoothest and sweetest brushed setup!

What reviewers say

Reviewers rate this 21-turn brushed motor highly, with all four reviews giving five stars. Two verified owners describe strong torque and good speed in 1/10 crawlers and Losi starter boxes, and report it lasts well, including under heavy race-day use. Fitment differs by chassis: it bolts directly into an SCX10, while a Wraith needs a small amount of material removed near a suspension link post, and a Losi starter box requires trimming the motor shaft to stock length. One reviewer suggests upgrading the stock plugs to Deans connectors for better performance, though this is optional. One review contained no usable text, and another was a brief non-English endorsement of durability.

  • + strong torque
  • + good speed
  • + resists burnout
  • + lasts well
  • − Wraith needs minor modification
  • − Losi starter box needs shaft cut
  • − fitment varies by chassis
