RC-Monster Forums - View Single Post - does drag brake use up any battery power?

Interesting thread, I'd heard rumors that brushless motors used battery current for braking, guess not. But are all BL esc's regenerative?

For that matter, it'd be cool to get a simple explanation of how brushed and brushless braking works. With brushed motors, is braking acheived by just shorting the + and - leads?

Or is reverse polarity induced?

I'm curious because I don't have the option of mechanial brakes, I have a 3906 Emaxx, actually it's 10% Emaxx and 90% battlebot.
And it's just over 13 pounds, so maybe I'll get some wicked regen power back?
