We recently flew from inside the car with 20 mph winds the problem is at what point your camera is going to start to flip.Not surprising being only 249g
What would you suggest it’s max wind level?
If power-to-weight ratio is kept constant then smaller drones will be less wind resistant. That's because mass (therefore power) goes approximately with the cube of the linear size, while surface area (and hence drag) goes with the square of the size. So as the size decreases, the mass and power drop faster than the drag.Size/Weight is really not a direct factor in how a UAS handles constant wind, propulsion power is. However weight would be a factor in how well it can handle wind changes.
Granted there is a correlation between power and size, but that's more related to available technology. After all, who would have thought a decade ago that a small aircraft like the Mini could fly for over 20 minutes in 15 mile winds on just onboard battery power?
I don't think you understood my post. A smaller aircraft does have less drag but, as size decreases, weight decreases faster than drag. DJI has kept power-to-weight somewhat constant, which is why top speed across the models scales with size. That is exactly the manifestation of the drag considerations that I explained above.Power is power and you need power to counteract an external force. If anything, a smaller size/weight would produce less drag, so a smaller force would be needed.
You can have a lot of power in a small space. Harder to do, and eventually will have physical limitations but still possible.
Also consider cars. Cars with smaller in size/weight can go a lot faster/have more power than decades ago.
However weight provides inertial damping which helps in abrupt changes in wind.
It's not really an independent variable though. They certainly could increase power, but that would decrease flight time.There's the key: DJI decided to keep power to weight ratio constant. They don't have to. I'm just saying in general, it's power that counts. It may be impractical or impossible to get the power needed in a smaller space or weight with, but it is still power that counts, and with technology developing, later it may be possible.
You're missing my intent. I'm just being general/theoretical. Intuitively one would think "it's small and light so it's not possible to handle wind". Not necessarily so. After all, one would not think a 250g drone could handle 20mph wind. But it can! It has the necessary power and means to transfer that power against the wind.It's not really an independent variable though. They certainly could increase power, but that would decrease flight time.
if you put in there a 6000kv motors and a 45A ESC and a 90C lipo - yes it will handle it fine.You're missing my intent. I'm just being general/theoretical.

i think it was really struggling when the forecast was saying it was 12mph wind in my area, it was screaming quite bad trying to keep the position. it was on .200 firmware, i didnot test it yet with .300 in the wind to see if it will show warnings or not in a similar situation.DJI specifies 8 m/s (18 mph).
