[E-Revonut]

70mm should be adequate! But this is rc-MONSTER, is there such a thing as overkill? the 80mm should run cooler but it is a big motor. RC-Monster Mike has raced an E-REVO with a 60mm Medusa. I run a 50mm in my crt.5 and love it. I would have bought a 60mm if they weren't sold out or a 70mm if they where out for my E-REVO. Instead I'm running a Tekno Neu 1515 2.5d on 5s. I tried 6s but that was insane! I would rather have something driveable than a speed/wheelie machine. Something in the neighborhood of 1600-1700kv is good on 5s, 60mm will do the job but will most likely run hot, 70mm would prolly be perfect, 80mm would run cool but you might sacrafice a little run time because of the bigger heavier motor. Good luck and welcome to RC-M
