Product Overview
The FL series UAV gasoline engine is a dedicated civilian internal combustion power unit independently developed for medium and large heavy-lift commercial unmanned aerial vehicles. Distinct from entry-level toy drone motors, this drone gasoline engine applies horizontally opposed twin-cylinder two-stroke architecture paired with full electronic fuel injection and circulating water cooling technology, specially optimized for continuous heavy-load long-endurance civilian aerial operations.
All core components including forged crankshaft, liner cylinder, full-function ECU control unit and dual redundant ignition coil adopt aerospace-grade lightweight alloy raw materials. Every finished UAV gasoline engine undergoes an 80-hour full-power bench aging test before factory shipment to screen assembly defects. We provide 6 displacement specifications (80cc / 120cc / 180cc / 320cc / 460cc / 580cc) to match different payload and flight range demands of global industrial clients. Whether users operate large farm aerial pest control, mountain remote cargo logistics, wide-area topographic mapping or long-distance infrastructure inspection fleets, this UAV gasoline engine can deliver consistent, stable power output without frequent shutdown maintenance.

FAQ
FAQ 1: What core advantages does this water-cooled UAV gasoline engine have compared with air-cooled drone gasoline engines and pure electric drone motors?
Pure electric drone motors rely entirely on lithium batteries for power supply, with continuous flight time generally limited within 40 minutes; heavy battery weight severely restricts drone maximum payload capacity. Air-cooled drone gasoline engines rely on natural air convection for heat dissipation, prone to overheating and power attenuation during full-load flights longer than 2 hours.
Our FL series water-cooled UAV gasoline engine uses circulating water constant temperature heat dissipation to maintain stable power output during all-day continuous operation. Its high-energy-density gasoline fuel supports 3–7 hours uninterrupted flight and can carry large-capacity spraying tanks, high-precision survey cameras and multi-functional detection equipment. This drone gasoline engine will not produce sharp power attenuation under low temperature or high-altitude thin-air conditions, with stronger environmental adaptability for full-day outdoor industrial tasks. In long-term commercial fleet operation, its daily maintenance only requires regular replacement of two-stroke lubricating oil and spark plugs, effectively reducing the comprehensive operation cost for global UAV operators.
FAQ 2: Can we customize power parameters, cooling systems and installation interfaces of this UAV gasoline engine for mass orders?
Comprehensive personalized customization service is fully supported for bulk purchase orders exceeding 20 units. Our professional aviation power R&D team can adjust engine displacement, maximum output power, propeller mounting hole size, exhaust pipe length and radiator size according to your self-developed drone frame structural drawings.
We can also upgrade the built-in EFI control program to match exclusive self-developed flight controllers, realizing customized real-time data feedback and safety protection threshold settings. For clients with special ultra-highland or extreme cold region operation requirements, we can modify the fuel injection system and water cooling circulation structure to boost extreme-environment stability of the drone gasoline engine. You only need to send UAV dimension drawings and detailed mission parameter demands to our global sales team, and we will deliver a targeted UAV gasoline engine matching solution within 2 working days.
