4.2 Test rig - terrytaylorbonn/auxdrone GitHub Wiki
Below is what I did for the FPV build (sawed some plywood, drilled some holes, then built the copter on that plywood, test flight).
TODO: I need to describe how to drill the holes and cut the board.
Note: My original setup was just a single piece of plywood. I kept things this way until I succesfully ran the first motor test (just turning the motors with no props). I thus avoided the expense and complexity of a frame build at the start, and instead focused on potential show-stoppers (getting the motors running).
