Anyone have experience with cheap 12s ESCs?

[Jahay]

i am already taking this esc into considering, i am seriously working out a way i can mount a braking system to my centre diff... But i am trying to get around how i can fit it all in as my motor doesnt sit parallel to the centre diff and the limited space in the tvps means i cant have a servo sitting directly next to the centre to control the brake mech.
Any advice would be much appreciated.






and consider how most systems operate...





any ideas where i could take a more appropriate system from?
