Nah, mechanical brakes just complicate things and clutter up the chassis and layout. ESC/Motor brakes are more than enough, even for experienced racers. Generally, nitro people who have just switched to brushless try out mechanical brakes on their new brushless setup because they are used to the feel of mechanical brakes, and are afraid the ESC/Motor brakes won't work for them. Once they try the ESC/Motor brakes, though, they eventually ditch the mechanical brakes because the ESC/Motor brakes are far easier to adjust, have much more adjustment, and literally never fade or wear out.
