I have two motors that the magnets have exploded
It looks like someone took a chisel to the end of the magnet
They are both can type brushless run on three li-po and both 5400 speed
One is an Eflite and the other is a Himax, unless they are both made by the same company I would doubt if it is a manufacturing flaw
Could it be over rev?
The windings look fine
Only a few runs on each motor
Any ideas?
