We've had a lot of buyers compare us to the DJI Agras line, and honestly, for the price point you're looking at, the HF T10 covers about 20-40 hectares in a 6-hour day with that 10L tank and a spray width of 3-5 meters — the centrifugal system really does give you better droplet distribution than standerd nozzles, so you're not wasting pesticide on drift.
The T20 bumps payload to 20kg and coverage up to 60 hectares daily, but what most people don't realize is the 14S 20000mAh battery actually runs cooler under load than the 12S on the T10, so you'll get more consistent flight times even in hot fields (usually 12-15 minutes per charge depending on wind).
Lead time is roughly 20 days or so, and we usually have stock on the T10, but confirm for the T20 since the Hobbywing X8 motors can move fast — we've had orders jump form 10 units to 50 units in a week sometimes.
One thing I'll flag: don't use this for ultra-fine dust applicaion like sulfur powder, centrifugal nozzles are really designed for liquids with a viscosity close to water, so if you're doing granular stuff you're better off with a different setup altogether.
The Microgram V7-AG flight controller is pretty much plug-and-play for RTK base stations, but you'll want to check your local frequency regulations cause ours ships with the 2.4GHz module by default — our company can swap to 900MHz if you need it, just mention it on teh PO.
Anyway, for the specs you're after, the 10L model runs about $6,500 FOB and the 20L is roughly $9,200, with a 1-year warranty but only 3 months on the motor bearings and battery cells — those are consumables, so plan for replacement after about 300 flight hours or so.
MOQ is 10 units per model for standard orders. We can discuss lower quantities for first-time trial orders, just get in touch.
Standard lead time is 15-20 working days after order confirmation and payment. Rush orders might be possible for an extra fee.
Yes, we include CE, FCC, and RoHS certifications with each shipment. A test report for the brushless motor and flight controller is also available on request.
The centrifugal nozzle adjusts droplet size from 100 to 300 microns, so it works with most liquids including herbicides and fungicides. Just make sure the mix is filtered to avoid clogs.
Store batteries at 20-25°C in a dry, fireproof container, and keep them at 50-60% charge if not used for over a week. Never leave them fully drained or fully charged long-term.
