If you race, the Tekin system is just leagues better than the MMM. It is smoother and more consistent from start up to braking. It also doesn't have hardly any drag on the motor too, so freewheeling is a lot easier too which helps in those tight sections of the track. I also believe it is a more durable system that can take the abuse of 1/8 racing. The solder tabs prevent damage to the windings. The motors run just as cool as the Neus, plus being sealed helps. The ESC runs ice cold as well, but the case is better built so it is more durable overall. Not too mention much easier to replace the fan. I The motors are just as efficient, if not moreso than the Neus.

The MMM is perfect if all you are doing is bashing around. Save the 70 bucks and get an extra Zippy lipo or something.

However, if you have any thoughts of racing, the Tekin system stands by itself right now and is worth the $70 premium. Without question.

Again, nothing against the MMM. I ran MMM all last year with great success and much of this year until the cases started failing on me taking out my ESCs with it. The MMM is a great system, but I think Tekin just perfected all the little flaws of the MMM.

To me, I rather pay the $70 premium and not have to worry... but that is just me.
