We run every unit through a full 20-minute hover test and spray calibration before it leaves the floor — that 20W engine gets checked for consistency at low and high load, usually 3-4 samples per batch pulled for random checks.

Most buyers use these for row crop spraying or disinfectant work in orchards, and the 55-minute flight time actually holds up pretty well even with the 9.2kg take-off weight fully loaded (spray capacity sits over 500ml with the liquid column setup).

The stainles steel frame comes in at 2kg, which is lighter than you'd expect, and the internal threaded connection means attachments lock in without wobbling — we've had zero reports of leaks at the joint in the last 300 units or so.
What it does is give you a C3-classified drone that holds tolerance on spray volume within roughly 5% batch to batch, and we back that with a COA from HPLC testing for teh spray system itself — not just the airframe.

1-year the TB65 battery and motor, but the spare parts support means you can swap a nozzle or arm in about 20 minutes if something goes wrong; customization is avaliable but lead time jumps to 45 days or so for non-standard colors.

We've been making these for about 18 months now, and the retest policy is straightforward — if first unit doesn't match the specs on your COA, we send a replacement before you return the original.
You can order just 1 set — no minimum batch required.
Yes, stainless steel holds up well against chemicals like pesticides and disinfectants without rusting.
We keep common spare parts in stock and ship them out quickly — usually within a few days, depending on your location.
The tank holds over 500ml, and with the 55-minute flight time, you can cover a decent area without refilling mid-flight.
Yes, the internal threaded connection makes it simple to switch nozzles or attach accessories without tools.
