I tried the kyosho diff in my buggy ( ratio = 4.3 ) and now the esc temps was cool but I think my 8xl was demagnetized it run cooler and he dont have heavier break power and overheat the esc very fast so I tried my neu 1509 2.5d 2700kv @ 4s it work fine the esc was cool and the batteries too but the motor get hot around 172f I think this can are to small for 1/8 rc's right ? and finaly I run my neu 1515 2.5d 1700kv motor and esc was cool but on 4s the power was not cool its a 5s and 6s motor for sure... later I tried my neu 1509 2.5d 2700kv in my 1/10 e-revo and overheat alot! this can are best for small lightweight rc like traxxas slash or hpi e-firestorm
