Basically, if you’re spraying row crops like wheat or rice, the 6-8m throw with four nozzles covers a lot of ground fast on that 20L tank and 25-minute flight—and the 49kg takeoff weight at sea level means you're not lifting much beyond the payload anyway, so IP65 rating keeps it running through morning dew and light mist better than some others we've seen in the field.
29000mAh or so of battery life is what you're planning around, since the 28000mAh pack usually delivers about 22–24 minutes in real-world conditions with a full tank, and teh plug-in battery swap takes 30 seconds or less once you get the hang of it, so a two-buyer team can run near-continuous shifts without needing the drone to cool down between loads.
We've been selling these units to regional cooperatives who rotate through peanuts, tubers, and even fruit orchards on the same day (adjusting nozzle height is quick), and the one-piece frame takes the abuse of field transport better than earlier modular designs that flexed at the joints—that folded size of 775mm×765mm×777mm slides right into the back of a standdard pickup truck next to the sprayer and a couple of spare batteries.
One thing it's not great for is ultra-dense tree canopies or any operation below 1.5m nozzle height, since the 6-8m spray width spreads fine above that but the downdraft can push residue into upper branches rather than saturating the lower third, and those conditions are better suited to a smaller machine with more nozzles per meter.
MOQ on the HF F20 is 10 units typically, and our company can include a basic charge station with each order for a small bump, though the 3-month warranty on wearing parts like the carbon-fiber booms means you'll want spare nozzles and prop sets on hand—most buyers go with the 20L tank for simplicity, but we can adjust the battery-to-tank ratio for the larger 28000mAh power bank if you're running extended flights over flat fields.
Also, the cord to the plug-in battery is actually a bit stiffer than the catalog shows, but it seats firmly with a satisfying click that doesn't loosen over vibration—a detail that matters more after 50 or so field swaps than on the first setup—and lead time is usually 4 weeks, though we've had 8-week spikes during harvest season when everyone orders at once.
We typically require a minimum order of 10 units for the HF F20, but we can discuss smaller quantities for initial trial orders.
Lead time is usually 15-20 working days, depending on stock levels and order size.
Yes, the drone comes with CE and FCC certifications, plus a full test report for the battery and frame.
The standard 4-nozzle setup gives you a 6-8m spray width, which works well for most crops. For fruit trees, you might want to swap to directional nozzles—we can help with that.
The 28000mAh plug-in battery is included. Store it in a cool, dry place at about 50% charge, and avoid leaving it fully drained for long periods.
