Various printed FPV drone frames

Various printed frames, the list starts with best flying frame and ends with prototypes:
- f404 AIO. Designed to have AIO inside the frame, which allows to use shorter canopy. m2x25mm screws should be enough for the stack with naked vista or analog vtx
- f404v1 similar to the first frame, but has 20x20 mounting holes and stack sits on top the frame. Use Canopy 20x20 vista with it to mount full size vista vtx. 30mm stack screws are suggested
- f403v2 box style frame similar to previous ones, flies good, pretty strong
- f701 light weight 7" frame used as proof of concept, it can fly, it is tuneable, but too weak, will break very easy even on harsh landing. Made of two parts to fit into print areas. Use m2 nuts and m2x16mm bolts to assemble the frame first, than super glue with soda to fully fix it
