Drone prototype.

An important question is which quadrocopters can be used and how. at the moment, I want to use two on different platforms.
The 0.5 platform that will be used as the current model will be used racing on a 200 mm frame. He can't fly normally. I have suspicions about the controller's abnormal work. He tries to roll over and gets carried away. But in principle it doesn't matter, it's just a model for demonstration.
The prototype is platform 1. For it, I will use the f-450 quadcopter / This is already a fairly powerful drone capable of carrying real cargo. According to my estimates, my version has 500 grams. if you use more powerful cells and batteries, then up to 1 kg at a distance of up to 20 km. Links to the melon drones page.

It is also necessary to remember that standard drones from below have equipment for flight and landing control such as a camera and a rangefinder. They will need to be moved to an empty place for normal operation.
