Love this 380 sized motor. Great startup and minimal cogging. I run this on a Mini Losi 8ight T with a 45A ESC and it is perfect balance between power and speed. Temps are good I can run a full 6 minute race on indoor clay on 2s with perfect temps.

Well this motor is heavy compared to similar motor of this size, seems to be a steel case (brused can?) not aluminium like most brushless motors. Using it on my 1/16 Turnigy Buggy and draws 23Amps on original ESC @2S and 17t pinion. (standar 15t).

Only has 3 mounting hole, 1 hole not threaded.

Good motor for the price, the motor mount space is not a standard size so it lost 1 star for that. screw size is 2.5mm I used this motor in a 1/4 HK gokart on 3s stupidly fast. im using the Track star Esc and it does not even get warm motor can stays cool

Quite heavy. The shaft is 3.17 mm. Fits 1/16 monster beatle but a different ESC needed.
