I purchased the 3 motors already. Just was hoping 1 motor controller shield could control them where i dont have to buy 3 ESC

Absollutely no chance whatsoever of driving an RC brushless motor from a motor shield designed for a DC motor.

Two reasons:

  1. brushless motors have winding resistances far lower than 2-wire motors (more than 10 times lower?) They can pull hundreds of watts per cubic inch, far higher currents are involved.

  2. RC brushless motors require sensor-less commutation circuit and 3-phase low-impedance drive. This is not trivial stuff, a brushless ESC provides the
    only cost-effective method, and yes you absolutely do require one ESC per motor.
