Do you mean the 2702V on V450D01? Since V450D01 uses BL main and variable pitch tail, 2702V would have to be regular.
The V400D02 stock brushed ESC won't work with it. You would need signal converters the other way to drive brushed ESCs and motors.
It should work with brushless motors on both. As usual, it may be a bit tricky to start the tail brushless. The tail output could be anywhere at start up instead at lowest throttle for the tail ESC to arm.
