Trying to learn how to build a drone? Just trying to pick the right parts out? Maybe you are a pro and you want to share your build or your knowledge with others. Check out DroneBuilder.io.
Here is an example of the results from a build calculation. Parts can be selected from dropdown menus or they can be added with custom properties: mass, current rating, KV, and more. Battery life, propeller thrust, and part-compatibility warnings appear with a single mouse-click. Builds can be saved and shared with the community and then filtered or searched by parts.
For those new or scared of building drones, a micro-blogging platform also lives on Dronebuilder.io called the Learning Hub. Anyone can publish articles to this hub with guides for anything related to multicopters.
