Max rpm is 100000. I only run mine on 2s a buddy has ran his on 3s and it s stupid fast. Havent seen anyone use 4s

That said.. I wouldn't take any of them past 50k RPM on a regular basis, a couple speed runs maybe but not normal or heavy use. If you do plan on having issues over the haul.

Mine is fast enough on 2S. Probably hit 50Mph when i had it in my slash
