Cardboard Corner Brace for FPV Drone Gates

Friction fit on the corner of a cardboard box to make some cheap FPV racing gates.

Assembly:
It works best if you cut “rings” out of the middle of box (ie cut off the flaps first). You can then cut it at opposite corners and trim the lengths of the sides to fit the gate size you want. I would recommend putting a strip of packing tape around the corner to make it less likely to come free when crashing into the gate, especially if you cut it down to size.
