Opening a Neu 1509 1.5D 4500kv

[Nard Cox]

That's the strange thing ... the motor keeps very cool 40c / 104F max, the ESC however is at 65c / 149F within a few minutes.

I bought the car / motor / esc / servo from linc (havn't seen him around for a while btw). He bought the motor used with just a few hours on it, than he drove it for a few hours and I haven't even driven it for a few hours. The motor should be in pretty good state. He also got the problem that the ESC was getting very hot, also due to a low airflow in the Hyper Mini STe.

So I have/had two problems:
1. The rotor of the 1509 doesn't feel to spin freely compared to my Neu 1512 and 1515.
2. The ESC was getting very hot when used in my Hyper Mini STe, the motor kept cool.
