hi everyone, i am thinking of building a special multicopter. i need to drop off a ~15kg packaged box from my rooftop to my building's back garden every morning. the idea is to mount it on a multicopter and throw it off the roof and have it SAFELY land on the ground each time, then come back empty to the roof. As I live on the top (10th) floor i would guess it is approx. 25 meters high.
