Well, with 419gr (14.78oz), 74,8mm (2,94 inches) and 2 poles i would say it plays in the same power league as a Neu 1515 or Lehner 1950. I know of one guy using this motor in his truggy. Watch
this video from minute 7 on and you will see a truggy powered by a Hacker C50 XL9. Power to spare and he never reported temp issues running on 5s 5000mAh kokam lipos.
