This is all down to a little device called an ESC, or Electronic Speed Controller. This is what translates a pilot’s controls into precise instructions sent to the motors to control movement.

How does a ESC work?

Electronic stability control (ESC) helps prevent a vehicle from skidding – and the driver from losing control of his or her vehicle – when turning a corner, braking sharply or making a sudden manoeuvre. ESC technology automatically activates the brakes to help steer the vehicle in the right direction.

Can I use different ESC on quadcopter?

Can we use a different brand ESC in that quadcopter or multicopter? The answer is, it might work, but not recommended. If you are desperate to fly, then by all means, you can try mixing any combination of ESCs and props that have somewhat similar characteristics.
