The question was asked about this: http://www.hobbypartz.com/elite-370-...ess-motor.html
I bought several of them and put one on one of my f45s. The motor ran so hot that I could not touch it. The EH200 on my other f45 is so much better.
I did not get one of the park motors so I can't give a comparison there.
My feeling is to stay away from those hobbypartz motors.
