Drones provide efficient transportation solutions in challenging environments, such as harvesting in mountainous orchards. Manual carrying of fruit to vehicles is replaced by drone lifting, allowing fresh fruit to be quickly loaded directly from the orchard. Especially mountain village construction and infrastructure projects, drones can easily lift heavy construction materials, significantly improving construction efficiency.

EFT D100 is a professional delivery drone with a maximum payload of 100 kg and an intelligent operating system. A single operator can easily control one drone for short-haul transport, reducing costs while improving safety in complex scenarios. Flight stability and endurance are key factors affecting delivery efficiency.

Now Let test the performance of the EFT D100 in full-load conditions.

Test Setup

1.Aircraft: D100 with ELM100 smart lifting system

2.Battery: Dual batteries (18S, 35,000 mAh)

3.Payload: 100 kg calibrated weights

Test Procedure

*In this test, the D100 was operated at full load and remained in a continuous hover throughout. The timer recorded only the endurance under full payload, excluding no-load and idle time during takeoff and landing.

Test Results

The test data shows:

1.At 30% battery remaining: 6 min 37 sec.

2.At 20% battery remaining: 7 min 28 sec.

3.At 10% battery remaining: 8 min 16 sec.

4.At 5% battery remaining: 8 min 44 sec; at this point, low-battery protection was triggered and the drone initiated a forced landing.

Test Conclusion

The test results show that under full load, the D100 achieved a max endurance of 8 min 50 sec. Built with a high-strength metal frame, the D100 maintains stable flight while carrying a 100 kg load. Its coaxial dual-rotor with 63-inch propellers delivers strong thrust, while the lifting module ensures that every flight is efficient and reliable.

*Note：Endurance test results are influenced by environmental conditions. Battery performance may vary depending on charge and discharge cycles. The data is only for reference. Flying at extremely low battery levels is not recommended.

For short-distance transport scenarios where mountainous terrain and limited access drive up cost, the EFT D100 delivers a reliable solution with stable performance. Its new smart lifting system is easy to operate and features a fuse that can instantly cut the rope if the payload becomes obstructed, allowing the drone to disengage safely. The EFT 4.0 intelligent control system supports both manual and automated operations, improving overall efficiency. Welcome to experience the EFT D100 and unlock more possibilities for drones in real-world operations.
