Feigao 9XL Failure

[glassdoctor]

Wouldn't this kind of damage be from impact, and have nothing to do with the voltage/load? I don't think a magnet can bust in half just from spinning itself.

Kinda like the LRP motors that suffer from the magnet coming loose from the shaft.. happens even on a 13.5 motor and I don't think there is even close to enough power for it to happen from sheer horsepower. I think it just happens from impact/shock load.

But who knows... that's just what seems logical to me.

I had an 8L go bad.. burnt windings. Then I ran the rotor from it in a Hacker C50 and that worked pretty good (very fast) but ran hot, and eventually got too hot and killed the magnet.
