F72 Agricultural Drone

Short answer: The F72 is an eight-rotor spraying drone with a 72 L tank and an 8–18 m spray width. Swap the tank for the 80 kg box and the same drone spreads granular fertiliser or seed. It suits spray contractors and large farms that cover open fields every day and need a machine they can rinse down and fly again the next morning.

Built for long days in open fields

Eight rotors give the F72 a stable, even downwash over the crop, which helps push droplets into the canopy instead of letting them drift. Two pumps feed 16 L/min to the high-pressure nozzles, and droplet size can be set between 30 and 400 μm to match the product label. For fine-droplet work, centrifugal nozzles are available as an option.

The frame is high-strength aluminium alloy with an injection-moulded ABS shell. The tank is rotomoulded to resist vibration. The whole body is rated IP67, so after spraying you can wash off residue with clean water.

Spraying and spreading with one drone

The F72 can work in more than one season:

Job	Payload	What changes
Liquid spraying	72 L tank	Pressure nozzles, or centrifugal nozzles as an option
Granular fertiliser	80 kg spreading box	Spinner disc, calibrate per material
Seeding (e.g. rice, cover crops)	80 kg spreading box	Lower flow setting, test on a small plot first

Flight control and safety

The F72 flies on an Android ground station with one-key take-off and landing. You plan routes by field boundary, and the drone follows them on its own.

• Breakpoint resume. When the tank is empty or the battery is low, the drone records where it stopped, returns, then continues from the same point after the refill.
• Terrain following. A microwave altitude radar holds the set height above the crop on uneven ground.
• Safety limits. A virtual fence, no-fly-zone checks and voice alerts keep the pilot informed during the job.

Batteries and charging

Each flight uses two 14S 42000 mAh batteries (13.5 kg per pair). With a full tank the drone hovers about 5 minutes. In real work it sprays, returns, swaps and goes again, so the number of battery sets decides how many hectares you finish. Most contractors run three to four sets with a 2400 W charger and a generator in the field. We help you size this before you order.

Who buys the F72

• Spray service teams that spray every day and need a reliable drone.
• Large farms and cooperatives with rice, wheat, corn or cotton.
• Dealers who want a flagship model to demonstrate, backed by spare parts and training from us. See our dealer program.
