8-Inch QUAD X4 FPV Payload Drone Industry Solution | 2.5kg Payload & Long Endurance, Covering Inspection / Aerial Photography / SAR / Surveying Scenarios

Solution Overview

This solution takes the 8-inch QUAD X4 FPV payload drone as the core operational platform. Leveraging its 8-inch large-wheelbase airframe with 2.5kg maximum payload, 12–15 minute endurance under load, multi-band high-power long-range video link, ELRS 915M/2.4G long-range receiver system and 0.01Lux ultra-low-light starlight imaging system, it provides high-mobility, cost-effective unmanned operation solutions for four core medium-load scenarios: medium-load industrial inspection, professional aerial photography, emergency search & rescue reconnaissance, and small-to-medium scale surveying & exploration. It addresses core pain points such as insufficient payload of small drones, excessive cost of large industrial UAVs and low efficiency of medium-duty tasks, achieving the optimal balance of efficiency, cost and maneuverability for medium-load operational scenarios.

Four Common Pain Points in Medium-Load Operations

1. Insufficient payload of small drones: 5–7 inch FPV drones generally have a payload under 2kg, unable to carry medium inspection equipment, professional cameras and other work tools. They can only complete light tasks and fall short in medium-load scenarios.
2. Dual shortage of endurance and signal at medium range: Endurance drops significantly under load, resulting in short effective operation time. Common video links have poor anti-interference performance, with signal dropout at medium range and in obstructed environments, limiting operating radius.
3. Difficulty mounting professional equipment: Professional work equipment is larger and heavier. Mounted on small drones, it causes center-of-gravity offset, poor flight stability and severe camera shake, failing to meet operational accuracy requirements.
4. Unbalanced operation cost: Professional industrial UAVs have high procurement and maintenance costs, making them very cost-ineffective for medium-scale missions. Manual operations are inefficient, high-risk and difficult to carry out in complex environments.
5. Limited low-light operation: Standard cameras produce poor image quality at night and in low light. Operations cannot be carried out normally at dusk, on overcast days or indoors, limiting working hours.
