The top speed can be taken as simply relative to a constant wind speed. Say they have a max speed of 30mph heading against the wind at 25mph. The net will simply be 5mph aka super slow.

Gusty wind is more complex as it depends on cumulative drag factor. You can estimate their forward drag by knowledge about the motors they are using (energy -> drag work).

Likely, unless their motors are tiny, the even the forward drag is quite high. This is why their max speed is not something like 300km/h.

TLDR: its just like airplanes only much worse
