Well Shawn it was your lucky day,

I was testing the V3.0_110211 and V3.0_110213

Both had very same bug,

i am testing all without Drag Brake, to prevent The temp, raise during Brake,
and to look at performance,
and all set with Forward/Reverse/Brake Function,

i was testing the Brake,
and both bug is, after Braking twice (2 times reverse throotle), it reverse,

our conclusion is that the Firmware did not detect the rotation during the 2nd reversed (while the car still moving Forward).

and what supposed to happen is, esc should detect zero rotation first, or very low rotation, and then reverse rotation.

But this one did not detect Rotation after twice reversed throotle.
