What is the wingspan of this drone?

An airtractor 502 has a 52ft wingspan and generally takes 65-70ft swath (so about 1.3x wingspan) and carries 480 gallons of spray and 200 gal of fuel. It works at about 145 mph. At 3gpa it will do a quarter in 1 load. It will complete this mission in about 30 mins.

So if this drone can actually take an honest 30ft swath it has to have at least a 23ft wingspan (and possibly more because it is lighter weight). 23ft wingspan is going to be a lot heavier than 55lbs, so thats a whole nother category of drone. Reguardless of category, 30ft is 2.3x less swath than 502 and probably not traveling 145mph either. So how is that drone going to get across the same number of acres in a very limited application window? What farmer is going to afford a drone that size?

It just isnt going to be practical for the avg farmer to have a drone spray his own crops any time soon.
