I have just purchased a MGM 16018 from them directly. I probably should have waited for Rc-monster to get them back in stock, but was in a hurry.
From what little I have ran this I can tell you it doesnt cogg at low speed, even compaired to my Novak HV its just a smooth. The size is better than expected, and I'm very pleased overall. I'm using 4s lipo on both a Neu 1512 2.5 and 1515 1Y motors. I prefer the 1515 Y due to the sheer torque. The real downside to this esc is that you really do need the PC software, and cummincation wire. I purchased the Programming card first and did not like it.
