Rotor Technologies and AG-NAV Inc. have partnered to enhance aerial applications with the Sprayhawk drone using precision navigation systems.

The Airtruck and Sprayhawk, both modeled after the Robinson R44 helicopter, are officially the largest civilian drones you can buy, each tipping the scales at a hefty 2,500 pounds max takeoff weight.

The R550X, based on the proven Robinson R44 Raven II, is engineered to carry heavy loads of up to 1,200 lbs or 550 kg.
