AF40 Helicopter Drone

The AF40 is an ultra-reliable workhorse unmanned helicopter designed for cost-effective operation and to require as little maintenance as possible. Built from a combination of carbon fiber and metal components, it provides an ideal balance between light weight and durability under demanding longterm industrial conditions. The sealed main gearbox features heat-treated steel gears and is designed to last for the entire lifetime of the aircraft.

The long-endurance platform features large-capacity fuel tanks that provide the base model with nearly two hours of flight time, and front and rear attachment points allow payloads to be connected and distributed to suit your specific mission requirements.

The AF40 ships as standard as a bare airframe without electronics or wiring, and ready-to-fly electronics packages can also be provided upon request. Three different quick-swappable engine options are available, all running on a gasoline/oil mixture:
