Fixed-wing drones, also known as fixed-wing UAVs (unmanned aerial vehicles), are a type of drone that use fixed wings and propellers to fly, similar to how airplanes work. Compared to other types of drones like multirotors and hybrid VTOLs, fixed-wing drones generally have a few key advantages and disadvantages when it comes to cost.
The Main Cost Factors of Fixed-Wing Drones
There are several main factors that contribute to the costs of purchasing and operating a fixed-wing drone:
- Airframe – The body, wings, tail, and structural components.
- Motor and propulsion system – Electric or gas motors, batteries, fuel, etc.
- Avionics – Flight controllers, GPS modules, telemetry radios.
- Payload – Cameras, sensors, equipment the drone will carry.
- Ground control station – Controller, software, display screens.
- Miscellaneous – Servos, wiring, landing gear, etc.
The performance, size, materials, and capabilities of each of these components greatly impacts the overall cost of the fixed-wing drone system.
Advantages of Fixed-Wing Drones Related to Cost
Here are some of the main potential advantages and cost savings of fixed-wing drones compared to other drone types:
- Aerodynamic efficiency – The fixed wing design is extremely aerodynamically efficient, allowing fixed-wing drones to fly much further and longer on less battery power compared to multirotors. This can save greatly on power system and battery costs.
- Fewer motors – Fixed-wing drones typically only need 1 or 2 motors to fly, whereas multirotors need 4, 6, or 8 motors. Each motor is expensive, so this is a significant savings.
- Higher payload capacity – The fixed wing design allows larger drones to carry heavier payloads for their size compared to vertical takeoff drones.
- Speed and range – Fixed-wing drones are generally much faster and have longer range compared to rotorcraft drones. This allows them to cover more ground for mapping/surveying jobs.
- Simpler maintenance – With fewer movable parts and motors, fixed-wing drones tend to require less frequent maintenance and repairs which saves on long-term operating costs.
Disadvantages of Fixed-Wing Drones Related to Cost
Here are some of the disadvantages and additional costs associated with fixed-wing drones:
- Takeoff and landing requirements – Fixed-wing drones usually require a good amount of flat open space for takeoff and landing. This means you may need to transport the drone to suitable locations.
- Runway or hand launch/recovery – Runways and launch/recovery equipment add to the system cost if required.
- Limited hovering/vertical flight – Fixed-wings cannot hover or fly vertically like multirotors, limiting their capabilities close to structures.
- Bigger storage and transport – The larger fixed-wing airframes often require more storage space and larger vehicles/trailers for transportation.
- Higher airframe costs – The materials, engineering, and manufacturing for the plane-like airframes can be more expensive than simple multirotor frames.
Typical Cost Ranges
Like all drones, there is an extremely wide range of fixed-wing UAV sizes and costs. But in general, these are typical price ranges:
Drone Type | Cost Range |
---|---|
Small hobbyist fixed-wing | $500 – $5,000 |
Mid-size fixed-wing | $5,000 – $50,000 |
Large professional mapping fixed-wing | $50,000 – $500,000+ |
The high-end fixed-wing UAVs used for survey, mapping, and other commercial applications can cost in the hundreds of thousands, but have immense capabilities in terms of range, flight time, and payload capacity unmatched by any multirotor drone.
Ways to Reduce Fixed-Wing Drone Costs
Here are some tips to potentially reduce fixed-wing drone costs if trying to save money:
- Choose a smaller airframe size – The smaller the aircraft, the lower the materials cost in most cases.
- Use lower cost construction materials like foam vs. carbon fiber.
- Opt for a simpler fixed-wing design – The fewer moving parts, the better.
- Use open source flight controllers and software – Avoid costly proprietary systems.
- Reduce unnecessary payload capacity if not needed – Only buy what you require for your application.
- Buy used/refurbished systems if available – Can save tremendously over new systems.
- Learn to maintain and repair the UAV yourself – Avoid expensive professional maintenance fees.
Conclusion
In the end, fixed-wing drones can be more affordable than multirotors for certain long range, high altitude applications where their aerodynamic and payload advantages shine. But their additional takeoff, landing, maintenance, airframe, and other costs can add up, making them less ideal for short range low altitude uses compared to vertical takeoff drones. Carefully analyzing your specific mission requirements and budget constraints will determine whether a fixed-wing UAV is the most affordable option or not.
