Hello everyone, First of all, im a newbie. I know almost nothing about drones and therefore I would realy appreciate your help. I am doing a project in which I need to fly several drones or mini drones in the same room. I googled it a bit and read something about 2.4 technology for anti-interference ( as you can see in this drone: https://www.amazon.co.uk/Syma-Explorers-Quadcopter-360-degree-Helicopters/dp/B00L54Y4X4) Do you know anything about this technology? I need to fly about 10 drones in the same room. Do you have any recommendations about drones that can fly together without interfering each other? (I want to control each drone seperately) I can afford spending at most ~50$ for each drone. I would apreciate any help you can give! Thanks
