Hey guys, my friend just bought his first hobby-grade rc car, The Traxxas Slash. I figured it was brushed so i wanted to break in his motor for him. I have SOME experience with brushed motors but not a lot since I've only owned a Stampede VXL and a Revo 3.3. What is the best break in technique would you guys recommend? I would submerge it into water, but i don't know how long it should stay there until fully broken in. Thanks!
