The 15xx Neu has 18mm dia. rotor.

well all i can add is that i have been very happy with my tekno neu

Yea Brian pointed out that it is the rotor/stator? not the can.

My cc 2200 ran much hotter than my neu motor. cc 2200 consistantly ran ~140 deg F

My T8 2050 motor barely breaks 100 deg F

Rotor is the magnet. 15xx doesn't refer to the magnet it means 1.5" stator diametre.

I don't think the holes in the neu's can are the temp difference between neu and cc motors. My Tekno 1515 1y (no holes in can) doesn't run noticeably different in temp on 4s, compared to my standard neu 1515 2.5d on 5s. Same car, about 1000rpm difference, same gearing, same race tracks, same type of cells.

Is tekno neu square motor made by neu or i is it like cc neu, only neu design? I think of square 1515 1y tekno neu or just 1515 1y neu - the firs one is cheaper, so what is your idea?

Sorry, I measued again last night, the CC Neu's rotor dia. is 19mm.:yipi: 1mm thicker than the original Neu, as I remember we've discussed somewhere in this forum.

The square can motors are genuine Neu's, made here. Only the can is different.

Thank you man, are their rotors same diameter as neu too? I can see cc neu is not exactly the same...

there's your answer. :lol:

Ok, just wanted to be sure. BTW, square can is perfect idea :)
