The F11 is a common beginner drone that has had many updates and versions while the basic airframe remains the same. There are not many accessories available for this drone and not many 3D designed & printed items either. That caused me to design a few things for my own use, which I am sharing here. This clip on bracket fits around the airframe and allows you to use a small zip-tie to attach the Firehouse Arc V Anti-Collision light to the this bracket, which can then be quickly attached or removed from the top of an F11 drone without any other fasteners.
