So you would like to program multiple drones to dance in sync? The ZEROSPACE Drone Formation Dance Set has you covered. It consists of 8 DOBBY drones with 3 formations and 10 flight patterns. One person can control these drones using an app.
The set comes pre-programmed, so you can start flying in 10 minutes or so. You will need a space of 5m x 5m to fly 8 drones. Pretty cool if you ask us. More info is available here.
