Wind Resistance Setup / Safe flight

Hello everyone,

I know there’s not a quick answer for this question.

But I’d like to know how to calculate/estimate the wind resistance for a specific multirotor setup. Is there any calc aproach or method to do that?

What I want to know is the wind speed limit I can flight in safety.

You can calculate the drag from a constant altitude flight in 0 wind, if that is what your asking.

In order to maintain a constant altitude you know the vertical component of the thrust must be the weight of the copter, from the lean angle you can then calculate forwards component. At a given lean angle you will reach some steady state speed and hence the forwards thrust component will be equal to drag.

Hi @iampete, what I want to know is the wind speed limit I can flight in safety.

There are too many variables to determine that. I have a small 210 quad that will fly in gale force winds, while a much larger craft is tossed around at 25 kph.

Regardless of props/motors size? vehicle weight/frame type?
