battery capacity for the original drone design In our previous article, we modelled the flight time of our drone with varying battery capacity (figure 2).įigure 2: Flight time vs. Our goal is to maximize our drone’s flight time so that it can hover as long as possible. Other components (camera, frame, ESC, etc.): 460.5 g.We will assume the following mass breakdown of our 777 g drone: Once we found the most efficient combination, we had the tools needed to estimate our flight time, which is where we will start off today.įor this article we will be more precise with the mass of our components. Following these assumptions, we predicted we would need 1.9 N of thrust per propeller for hover flight, so we looked for the motor-propeller combination that would be most efficient at 1.9 N. We started our design process with the assumption that our drone would weigh 777 g and would be able to fly on its own. In this article we will start where we left off, looking at how our assumptions held up. In our previous article, How to Increase a Drone's Flight Time and Lift Capacity, we covered the first stage of the design process and reached a first version of our design.
