Hello everyone, I am posting this thread to let everyone know that if you damage, break, or don't like to use the wooden booms for electro hub I have a solution. I caded up a design for the spider quads arms. There's 2 pieces, the front arms, and then the back arms. Basically if you have a 3D printer, or know a friend who has one you can 3D print these arms. They work just as perfect as the wooden ones. Also you can make more if they do break, which mine haven't yet. If anyone is interested Ill give you a link to download the files.
