other good feature for the mmm to add....a Motor blocked protection

or a feature for the esc will be able to detect that the motor have a problem like a bad pluging , wire shorted or a to hot motor at this time the esc detect the lost of magnetic property of the rotor...and shut down the esc ..at this time we will be able to know that the motor is the problem,just add led flashing code saying that...(i hope im clear!!loll)
and a option to activate the fan by the software(always spinning),,,,could it be a good thing when running in really wooot condition
