Castle 3800kv question
 
Anyone know what the max rpm for this motor is? I know castle says 2 and 3s, anyone ever run it on 4s?

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

All brushless should be around 30k RPM for best effeciency and life span.

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.
