Dronehook A1 (touchdown self release)

Here is one solution for drone hook (touchdown self release) First goal was to avoid electrical instruments (bluetooth, wifi, RC). My design use gravity and elastic deformation. 2 part are printed together, so there is no assembly time thanks to 3D printing. Also is bending part structure very specific that can made only using 3D printing. You can transport and release packages in location where is no human resource who can help release package advantages using rope+self realase hook: +suitable for all drones +rope don’t interfere drone landing +unhooking don't need professional pilot (even case of variable wind) Watch video about working principle and how additive manufacturing possibility change my design https://youtu.be/r3WASJ5eEVg
