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.

  1. The Parrot AR.Drone is a fantastically capable platform, but I wouldn’t call it a complete package. Until they include a remote control or make it compatible with standard RC controllers out of the box, it will remain an iPhone accessory to me.

    Kudos for ease of repair and spare part availability.

  2. Fair point! You do need to supply the smartphone or tablet to control the AR.Drone. Parrot has a compatibility tab on their support page, which tells you exactly which devices it will work with.

  3. I don’t see the HoverFly kit listed !!! Those are awesome kits !

    1. Yes, that’s a good one to add to the list. Thanks for mentioning it. Hoverfly makes some very nice flight systems, boards and accessories. I almost included the Parallax Elev-8 quadcopter (http://www.robotshop.com/parallax-elev-8-quadcopter-uav.html), which uses a Hoverfly control board.

    I really like that tricopter build. Although the component table needs a correction for the speed controller cost – 3 of those will be $23.40 (the table shows $9.40). its still a lot of tricopter for the money. This will go onto my list of new years projects, thanks for posting this.

    1. Whoops! Good catch, Michael. I’ll see if we can get the cost table updated. I’m hoping to make this one in the new year too. Let me know how yours goes!

    Walkera has a new model called the Infra X, which is slightly bigger than the ladybug. It has sensors that allow it to avoid walls and the ground. Around $100.00, hard to find, but the videos look awesome.

    1. Nice find. That does look really cool. Did I mention that the market for small quadcopters is evolving at an incredible pace? You should definitely shop around and see what is out there before you buy. Be sure to check for independent reviews so you can be reasonably sure you are getting a quality product.
