Mark Harrison made a quadcopter body out of sections of pool noodle, producing a UAV that's cheap, rugged and great for practicing on. As he points out on Make, the beauty of multicopters is that they don't have to be aerodynamic and their bodies don't have any moving parts, giving you lots of flexibility in design. Plus: "Let's face it, it's just funny to think of flying pool noodles!"
In keeping with the spirit of a pool noodle quadcopter, I wanted the construction to be as simple as possible (for example, the motors are taped onto the arms). I bodged it together in an evening with materials that were at hand. While originally done as an experiment in minimal design and construction, I was happy enough with the results that I fly it regularly and use it as a trainer when somebody wants to try flying.
If you build something like this, I encourage you to keep to the original spirit of the thing: improvise, have fun, and don’t be afraid to try out new ideas!
