Various Hacker motor questions

[lincpimp]

Thanks for the info lutach. Do you think the kv changed when you swapped out the rotor shaft? I have a spare 13l c50 and really like how the c50 maxx wind does in the buggy, just not liking the broken shaft!

Does hacker repair motors? I guess I could request a 5mm shaft to be put in the motor, or maybe do it myself? I guess that the magnet is glued to the shaft pretty well, so that may be out of the question. I could weld another end back on and have it turned to 5mm.
