Compare
Two aircraft. One decision.
Same mission language, same dealer network, same compliance path. The difference is how much one pass carries, and how many acres fall in a day.
I-19
Choose it if you run mixed work: spray and spread on the same day, on fields that are smaller, wetter, or harder to reach. Twenty gallons keeps the aircraft light and the turnaround fast.
R-40
Choose it if the constraint is refills. Forty gallons and a swath up to fifty feet mean fewer trips back to the tender and a longer working pass on big, open acres.
