The DJI Agras T50 is the aircraft most Australian contract drone sprayers are running, and it's the one Veldta Tech is built around. Here are the real numbers — straight off DJI's published specification, not a brochure headline.
A 40-litre spray drone with a coaxial dual-rotor layout, 54-inch propellers, dual active phased-array radar and binocular vision — rated by DJI at up to 21 hectares an hour.
The T50 sits in the sweet spot for contract work in Australia: big enough to be commercially viable on real paddocks, small enough to travel on a single trailer with a generator and batteries. Swap the spray tank for the spreading hopper and the same airframe places 50 kg of urea, seed or bait per load.

Bigger isn't automatically better. Tank size drives how far you fly between refills, but it also drives weight, transport, licensing and the size of the launch area you need.

Dashes mark figures DJI doesn't publish on the model's public spec page. We'd rather leave a gap than guess a number you might plan around.
Detects obstacles out to 50 m and follows terrain as the ground rises and falls, so height above crop stays constant on a slope. Works in dust and at night, where camera-only systems don't.
A second, independent sensing system covering 0.5–29 m. Two different technologies looking for the same hazard is the reason the aircraft can be trusted to fly a paddock autonomously.
Centimetre-level accuracy against a base station, not the metre-or-two of plain GPS. That's what makes flight lines repeatable and keeps overlap and buffer zones honest.
Eight rotors on four arms. Redundant lift, better stability in gusts, and downwash strong enough to push droplets into a closed canopy rather than letting them sit on top of it.
9–12 minutes to recharge on the generator. With a rotating set of batteries the aircraft spends its day flying rather than waiting on the charger.
Every mission records the area flown, rate applied and track. That's what becomes your proof-of-application record — useful for you, essential if anyone ever asks.
That figure is DJI's, measured in ideal conditions at a low water rate with everything going right. It is not what a day looks like.
In the paddock, the aircraft's flying time is only part of the job. There's mixing, filling, battery swaps, moving between blocks, waiting out a wind gust, and the setup and pack-down at either end. A realistic honest day is:
| Job type | Realistic daily output | Limiting factor |
|---|---|---|
| Broadacre, 20–25 L/ha | 120–150 ha | Refill and battery cycle |
| Broadacre, 40 L/ha | 70–100 ha | Water volume moved |
| Orchard / vine | 40–70 ha | Canopy, water rate, block layout |
| Spot spraying, steep country | 3–5 ha/hr flown | Terrain and target density |
| Spreading urea | 8–12 tonnes | Ground crew loading rate |
We quote off these numbers, not the brochure ones. It's the reason our quotes hold up.
