At farm shows, many friends often ask us: why are most drones on the market built with single propellers, while DJI’s T50 and T100 models use a dual-propeller design?
Today, let’s look at the differences from three perspectives: application, performance, and safety.
Single Propeller: Light and Flexible
Typical examples: Consumer drones (aerial photography, recreational use).
Features:
- Simple structure, lightweight, and low cost.
- More than sufficient for photography, research, and light inspection tasks.
Best suited for: Hobbyists, photographers, and research users.
Dual Propellers: Power and Safety Combined
Typical examples: DJI Agras series.
Features:
- Greater lift: Capable of safely carrying tens of kilograms of fertilizer or liquid.
- Better stability: Dual propellers rotate in opposite directions, canceling out torque and ensuring stability even in windy or heavy-load conditions.
- Safety redundancy: Even if one propeller is damaged, the other can still provide thrust to ensure a safe landing.
Dual Redundancy System: More Than Just Propellers
- The dual-propeller design acts as an added layer of insurance for flight.
- If one system fails, the backup immediately takes over.
- For agricultural operations and long inspection tasks, this means fewer accidents and higher reliability.
What This Means for Farmers
- Higher efficiency: Heavy payload + long endurance allows more acres to be covered per day with stable, uninterrupted operation.
- Lower risk: Reduces potential losses caused by equipment failure.
- Better return on investment: Equipment is more durable, more reliable, and offers greater cost-effectiveness.
In Summary
- Single-propeller drones: Lightweight and flexible, ideal for photography, research, and recreational use.
- Dual-propeller drones: Powerful and safe, designed for high-intensity agricultural and industrial tasks.
- Dual redundancy systems: While they are more expensive to build, DJI’s pricing remains accessible. This not only lowers the barrier for farmers to adopt advanced agricultural drones but also allows users to confidently treat drones as real production tools.
