i want to see a way to reproduce these "facts" in a way that Everyone can try and see.
as i took the motor and esc out of the truck and mounted it on the bench and powered it up and did some more testing with it.

and with the motor at 75% brake force and with breake on i drove the brushless motor with another Brushed motor runing on 12v @ 15amp .
and the brushless esc did get Very warm But did NOT show a positive output on the battery connector all i got was a constant dip or drop in voltage as the esc applied more voltage to the Brushless motor to try to hold the motor still .

you cant make the test more Simple than this setup and its one EVERYONE can do.

Note when testing
when you brake ......2 coils get a voltage 1 on eatch side of the armature
the harder you brake the higher the voltage..... in turn slows the armature and or holds it or in place.

its just a way to test this that ALL or everybody can do and only takes 10 to 15 minutes to setup.
Videos are welcome as it is easy to "say" but better to prove.


Just Fix It !!!

All you need to be able see the voltage spike and some reverse current during braking, is a Datalogger like the one I use by Eagletree. As simple as plugging it in series between your battery and ESC.
