I would like some opinions/advice from anyone who has changed the motor to a lower kv in an arrma 1/8.
I currently have a turnigy xk4074 2000 kv motor.
Running 17/50 gearing on 4S it's right up to the limit in terms of temperature at about 65-75c (149-167f) on 4S but on 6S it goes above 90c (200f). I'm concerned this is too hot and I might end up destroying the motor again like I did with a hobbywing 2200kv (the rotor magnets shattered).
I have bought a turnigy xk3674 1650kv in the hope that a lower kv will lower temperature. However since the motor is narrower and is easier to turn I have doubts on this.
Can anyone share experience or recommend a motor that will run cooler than my 2000kv?
I don't want to gear down because I want decent speed. Looking for just under 40mph on 4S and 55+ on 6S.
Thanks.
