I agree. I get fairly bad range in my small city, even with line of site. I get serious lag at around 2km. In places with less interference, it only bumps up to around 2.75–3km. It’s advertised as having 10–15km range or something.

On the other hand, 3 batteries in a Mini 3 is pretty much guaranteed to keep it in the air for 90 minutes. It’s very impressive. Our custom quad manages more like 20m per flight with twice the battery capacity (though, twice the weight as well).

tbh, once you realise you can get in into FCC mode, the advertised distances become a lot more realistic... :)
