About this 3D model
This was my build of the 99$ FPV racing drone by UAVfutures: https://www.youtube.com/watch?v=Avp8MurmeEY I designed these feet to land easier and to protect the frame from hard impacts. My first design(V1) weighs less but will break easier. My second design(V2) is stronger and will take harder landings. Just use an M3 x 15 screw and a M3 nylon nut to secure the feet to the frame.
