I have not heard much about this motor other than the fact that Bob Novak even quoted it as a good motor when they were testing new winds of the HV motors in 1/8 scale buggies. He said it was similar to a HV5.5 motor they were testing.

Sub 7lb, lowest CG of any 1/8 buggy
There are several guys where I run that use this motor on 4s. I've tried it myself. Yes, it's a little much, but the power is manageable and well suited for a buggy application. The Kv rating is a little high, but it's an Neu and it runs cool. 20-30 minute mains are no problem with this motor. I prefer the 2d/f, which is a little tamer.
