Genuinely surprised the flip managed to reach 500m! Though I just saw it has a weight of 249g like their Mini lineup. I haven't pushed my Mini 2 that high before, I think the highest is about 360m in the middle of nowhere in Armenia. Absolutely zero wind in that environment I flew in. Usually I'd start getting a strong wind warning around 120m back in England even if things were relatively smooth on the ground.

500 meters is the maximum altitude of my drone to reach.

A major bit of advice I'd give for flying high though is take a look online at general flight traffic for planes and helicopters in the area first. See if it's likely that anything might fly in that area throughout the day. The main thing that stops me from flying high is never the wind, but the fear that I might cause an accident that was so stupidly easy to avoid. But when I know it's all clear from researching first, I fly it all over the place ;^)
