Drone Flying Sim – a free 3D flying simulator. In this simulation, you will get to fly a drone around a city. The objective is to take the drone to the endpoint without crashing. To do this, you need to start at one point in the city and make it to the other.

In this simulator, you will get to control the drone fully, moving up, down, left, and right. This gives you the ability to go up and over or round.

The city is made up of a lot of different buildings, roads, and other structures. Some of these buildings have a roof, and some do not. This means that you will need to go up and over or round the buildings to get to the other side.

Even if you do already own one, you will not always be able to get out and fly one around the city. This is because some of the buildings have a roof and others do not.
