How it works

1

Flight planning

Sprayhawk integrates with AG-NAV's mission management software to plan the flight and the chemical application.

2

Transport and setup

Tow the Sprayhawk on-road with the included transport trailer and set up in under 15 minutes. No aircraft unfolding or assembly needed.

3

Get set and go

Automated missions follow pre-programmed routes with minimal pilot intervention.

4

Cover 50+ acres per refill

Sprayhawk’s 110 Gallon useful capacity means you’ll make short work of large fields, covering hundreds of acres an hour.

5

Refuel and refill

Precision landing capability means you can use your existing tank truck to refuel and refill with ease.

6

Post-flight review

Analyze system logs and camera recordings to verify application success and safeguard against liabilities. 

THE FUTURE OF AGRICULTURE IS HERE

“The Sprayhawk is going to be the future of aerial application. AG-NAV is excited to work with Rotor to bring our state-of-the-art navigation and planning solution to the platform.”

Fred Ramirez
President, AG-NAV

“The future of agricultural aviation is unfolding right now, Rotor is positioned to make a huge impact on productivity and safety.”

Lukas Koch
Chief Technology Officer, Heinen Bros.

“Since it can perform a wide range of missions, from agriculture to entertainment, with high efficiency and safety, there's little doubt that we will see more of these aircraft in the future.”

FAQs

Can you convert my Robinson R44 into a Sprayhawk?

The Sprayhawk is sold as a “factory-new” product based on overhauled R44 airframes. For fleet operators, Rotor offers the option of retrofit conversion. For more information on retrofit and core exchange options, please contact us.

Can I use it to carry people?

Rotor's UAVs are heavy lift drones designed for utility missions like agriculture and firefighting. They are not certified to carry people.

What licenses do I need to fly the Sprayhawk?

To fly a Sprayhawk as a Remote Pilot in Command (RPIC) in the US, you must be an FAA-certified Part 107 remote pilot and complete Rotor's factory training course. These requirements may change as technology and regulations evolve. Operators in the US will also be required to have a Part 137 license if they wish to apply chemical.

How many acres can it spray in an hour?

The Sprayhawk can spray up to 240 acres an hour, carrying a payload of 110 gallons and spraying at 50 to 60 knots with a 65 ft swath width and a 2 gallon per acre application rate. The number of acres per hour will also depend on terrain, chemical application rate, altitude, winds, obstacles and other factors.

What is your relationship with Robinson?

Rotor is an independent company from Robinson Helicopter Company (RHC). However, we collaborate closely with RHC on engineering, certification, and supply chain. You can read more about this here.

What regulatory permissions are needed to operate a Sprayhawk?

The Sprayhawk is delivered with a Special Airworthiness Certificate (SAC). A §44807 exemption will be available to agricultural operators of the Sprayhawk for commercial aerial application and other low-altitude agricultural missions. 

The FAA is currently in the process of transitioning large UAVs like the Sprayhawk to a new set of rules governing the operation of large unmanned aircraft at low altitudes, colloquially called “Part 108”. The Sprayhawk has been designed to be compliant with all FAA Part 108 requirements.
