Motor brakes or mechanical?

[Mozzy]

I know & understand what's been mentioned here, but, in the past I've heard from a few electric brushed & bl racers that the ESC's aren't designed to feed eletricity backwards & are only designed to draw it from the battery.

Can this be confirmed by an actual ESC designer & not by someone that assumes?

Perhaps someone from Castle, Losi, Novak or LRP R&D?

I think only one of these people would be able to give a definite answer.

I don't care if you're an electronics wizz or have a degree in the field. I want to hear from an actual designer as they'd only know what's truly going on with their product & could tell you exactly what's happening.
