Motor braking.

[GriffinRU]

Most of it will be absorbed by motor, some by batteries...

It would be really hard to measure with eagletree what's going on with braking with normal approach, but if you add current sensor on one of the motor leads then you can measure what we are looking for. But to make it clear what has more or less harm ABS or proportional braking would be still difficult. And even with the last one it would be impossible with eagletree's resolution to see anything useful...
