Various Hacker motor questions

[lincpimp]

That is a great price on the rotors, did you get them from hacker directly? I see that their site is under construction at the moment.

Also did the kv change with the different rotor? I guess that I could contact them about repairing the shaft? Not much point if the shafts are so cheap. Wonder if I can get it with a 5mm shaft?

I have a c50 14l in my new emaxx on 5s and it is killer, plenty of power!

And I have read that the b50 motors have different magnets than the c50 motors. The c50 appears to be better, as it has segmented magnets, like a lehner.
