Various Hacker motor questions

[lincpimp]

So I finished my hyper buggy with the hacker c50 maxx motor.

The motor shaft broke on me earlier, it is only 1/8" so that was almost expected!

Anyway, I have quite a few hacker c50 motors, and the c50 maxx is the same can length as a c50 l but has a shorter rotor inslide, looks to be s length. Wondering if I can replace the broken rotor with one of the l can rotors, that also has a 5mm shaft.

Now I do realized that all of the rotor assemblies are the same, only the windings change to alter the kv in the various winds in a certain can length.

Wondering what the l length rotor would do to the kv rating of the c50 maxx? I can only imagine that it would be lower, due to the increased weight of the rotor. However it would have more magnetic strength than the shorter magnet on the original shaft.

So any info would be very helpful. I can always try it out and see, but it would be nice to have some info. Not too fond of blind testing!
