This my tricopter based on David one`s and I build it with my father but I changed some things.
Before I used aluminium tubes I had carbon squer tubes but they broke two times. Afterwards my father suggested to use the aluminium tubes and squeeze both ends.
We also construct and mill-cut a new camera bracket and the yaw control.
We adapt the tri-body from David for 10 mm tubes to 8mm and cut it with a CNC-cutter and I use the kk 2.0 control board.
