Maintaining/repairing electric motors

Buying a new motor is exciting. You think of the extra performance you're going to get from it, or the extra long flight times from a super-efficient motor, or just the great feeling of having something new on your plane.

But after you crash, motors require stuff like replacement shafts, re-soldering of any broken connector wires and even occasionally gluing magnets back in. Some people will just chuck a $10 motor in the bin and start again, but like most foamies after a crash, they can be saved very cheaply and easily.
