wanna try sensored

[suicideneil]

If you dont trust the MMPro with a tekin motor ( ~1400kv should be good for 4s lipo & 30-35mph ), then you dont really have many other options- the hobbywing sensored systems are said to cog a bit even though they are sensored, and that just leaves a novak hvmaxx system or a full tekin rx8 system..

I used a Hobbywing XERUN 150A sensored ESC with Tekin T8 1900kv in my XTM Rail and it was pretty smooth. Not as smooth as my RC8Be with a RX8/T8 2250kv setup but not too far away. It never cogged but it didn't start as smooth as it did with the Tekin ESC. It would kind of do a little lurch forward at the smallest throttle input but once on the way it was very smooth indeed. Power was very progressive. Was pretty surprised that a Chinese ESC could be that smooth.
Still if you want ultimate in smoothness then go with Tekin RX8/T8 combo but T8 motor with MMP should do a pretty good job too.
