Motor braking.

Since when are the motor brakes regenerative brakes? I thought they were just a reverse torque.

I do know it's quite hard on the esc, both the harder you brake,the weight of the RC, and gearing. Most of us use motor brakes, as far as I know.

I think this MAY have been a factor why my Quark capacitor blew, I turned the braking setting to double, very hard on the caps.

Rene correct, when you apply brakes ESC shorts the windings and can do that with bursts simulating ABS...

Also each FET has a built-in diode which works as an H-bridge with other FET's, thus charging battery and cap if generated voltage higher then battery voltage( accelerating going down hill or bursts after jump). Caps usually take care business here and if connection between batteries and ESC is not good then often fail...

So, when you use motor as a brake then you put motor in bad situation because now it need to absorb kinetic energy of rolling vehicle (mv^2) and do that fast. Think, you Ok with accelerating within couple seconds but you would like to stop on a dime, right? Do the math then.
For controller it is up for caps how good they are and how good is battery connection.

Really, I thought it was something a little different.

BTW, when my truck is not moving, and you apply the brakes, you can hear a buzz, like pulses. This is the Quark, i love the brakes it has, they are super smooth, and never lock up.

So I suppose these ultra caps should do an excellent job for braking.

If they are discharged! Getting idea?

Why would they have to be discharged? It would be as long as the potential is greater than the battery...?
