My quadcopter frame has holes spaced at 45 mm to accomodate most of the flightcontrollers. This was a bit of a problem for me since I am using relatively small boards such as NanoWii and Naze32. So I created these small adapters to be able to mount those small flight controllers on larger multirotor frames. The NanoWii version is for flightcontrollers that have 30mm spacing and the Naze32 version is for 30.5mm spacing. If there is interest I will try to make a customizer version.Use M3 (nylon) screws, nuts and/or pillars to install. Holes may need to be drilled to fit the screws.
