Electronic Speed Control (ESC) $17.78

In order to run the brushless DC motors used in most aerial RCs, you need an ESC. The Exceed-RC Proton-30A model pictured below is pretty nice. However, you need to match the current specifications of the ESC to the requirements of the motor. You need one ESC for each motor.

Most ESCs also include a linear Battery Elimination Circuit (BEC) to provide 5 to 6V for the control electronics. Read more about this under the UBEC accessory heading in this article.

What it Does

An ESC connects to the supply battery and receives control signals from the aircraft’s receiver. It outputs the desired power to the brushless DC motor.

Why it’s Cool

Nothing too fancy here, but if someone is building their own drone, they’ll need these. The price is very reasonable, so perhaps this gift will help someone you care about complete their project.
