We've been moving these for about three years now, and the first thing most buyers ask about is that 16-nozzle configuration—it's what really sets it apart form the smaller rigs, because you're covering 8 to 18 meters per pass depending on how high you fly, and the flow rate sits at 16 liters per minute, which basically means you can knock out roughly 30 hectares in an hour if conditions are right.
The 72-liter tank is standard, but we've seen a lot of guys upgrading to the 82-liter option for bigger fields, and teh spreading capacty of 80 kilos for granular stuff handles fertilizer or seed pretty well—just keep in mind the max takeoff weight is 166 kilos, so you're carrying about 110 kilos of payload when you factor in the battery weight of 13.5 kilos per pack (two of them, 14S 42000mAh each), and the hover time at full load is 25 minutes or so, which is decent for a machine this size.
One thing I always mention is the IP67 rating—it's not just splash-proof, you can actually hose it down after a day in the field without worrying about the electronics, and the aerospace aluminum and carbon fiber frame holds up well, but the core components like the motors only have a 3-month warranty, so we usually recommend buying an extra set of nozzles upfront because they take the brunt of the wear.
flight speed of 15 meters per second is fine for most spraying, but you'll want to dial it back if you're doing precision work near boundaries, and the atomizing size ranges from 30 to 400 microns, which gives you some flexibility depending on whether you're applying herbicides or fungicides—it's actually better suited for broad-acre crops than for orchards with tight spacing, just so you know.
Lead time is usually 20 days or so from order, but our company can push it to 2 weeks if you're in a hurry, and the triple satellite GPS system handles terrain pretty well up to 4000 meters altitude, though operating altitude should stay under 20 meters for consistent coverage—anyway, most buyers go with the standdard 72L configuration unless they're running really large blocks.
Yes, the HF T72 comes standard with a 72L tank but can be upgraded to 82L by swapping out the tank assembly. It's a direct replacement, so no major modifications are needed on the drone itself.
We provide a CE certificate and a detailed test report for the IP67 rating. For the core components like the motors and batteries, we also include a 3-month warranty document along with the 1-year overall warranty.
The 57kg is without batteries. Each 14S 42000mAh battery weighs 13.5kg, so with two batteries installed, the drone comes to about 84kg before adding any payload.
We can do a single unit as a sample order, but the lead time for that is about 15-20 days. For bulk orders of 10 or more, we can start shipping within 30 days after payment.
The drone ships in a reinforced wooden crate with custom foam inserts for each part. It's folded down to 990×860×2090mm, so you just need to unfold the arms, attach the nozzles, and pair the remote — no assembly tools required.
