1900kv on 8S Before i switched to TP motors i used run goolRc 4082-1900kv on my hobao. Somehow it feels so much better reaching 130mph on 35$ motor, tweaked, bearings upgraded and overvolted, than some out of the box top performing high-end motorYes, that supposed 2050kv stocker is always around 1900kv on my motor analyzer. All of the ones I have. A great candidate for 8S running. I am using Hybrid Ceramics on 2 of them now. For high sustained RPM's, the stock motor bearings are the weak link out the box.
