Product Brief Introduction
The ZT-350cc UAV engine is a professional civilian drone gasoline engine independently developed for medium-load commercial unmanned aircraft. As a compact-displacement UAV gasoline engine, it fills the performance gap between small consumer drone motors and large heavy-lift drone power systems.
This drone gasoline engine adopts mature air-cooled cylinder structure and two-stroke power layout, realizing the perfect balance of compact size, sufficient thrust and low fuel consumption. The whole unit is precisely machined with aluminum alloy materials, effectively controlling overall weight while enhancing structural rigidity to resist vibration during high-speed flight.
Different from low-power small drone motors, the ZT-350cc UAV engine is oriented to professional civilian aerial industries. It can carry stable medium payloads, maintain stable flight at high altitudes and complex temperatures, and has become a mainstream cost-effective propulsion choice for aerial mapping, agricultural inspection and commercial aerial photography drones on the global market.

Detailed Structural & Technical Highlights
High Adaptability Air-cooled Cylinder Assembly
The core of this UAV gasoline engine is a thickened heat dissipation fin cylinder block. The layered rib structure expands the heat exchange area, ensuring stable temperature output even under continuous full-load flight at 6000m altitude. The cylinder surface adopts anti-corrosion oxidation treatment, resisting dust, moisture and temperature fluctuation damage in outdoor wild working environments.
Energy-saving Two-stroke Fuel Supply System
Matched with standard 25:1 oil-gas mixing lubrication design, this drone gasoline engine achieves ultra-low fuel consumption of 0.55kg per kilowatt-hour. The built-in stable oil circuit avoids fuel supply jitter under variable altitude and load, reducing carbon deposit accumulation inside the cylinder and extending the overall service life of the UAV engine.
Lightweight Integrated Compact Layout
The engine’s internal crankshaft, ignition assembly and pipeline interfaces are pre-integrated in the factory. The total weight is controlled at only 12.5kg, which will not bring excessive load pressure to medium-sized drone airframes. Reserved standard fixing lugs support direct installation for most mainstream civilian drone models, eliminating custom machining costs for buyers.
Built-in Auxiliary Power Generation Function
Equipped with a built-in power generation module that outputs 120W stable power at 5000rpm, the UAV engine can supply continuous electricity for onboard cameras, mapping sensors, communication modules and other payload equipment, without additional external power batteries to reduce drone dead weight.
Civilian Commercial Application Scenarios
This ZT-350cc drone gasoline engine is only applicable to non-military civilian industrial and recreational UAV projects, covering multiple mainstream global commercial fields:
- Aerial survey & mapping: Medium-range terrain scanning, land resource survey, highway and construction site monitoring
- Commercial aerial photography & film shooting: Long-endurance landscape shooting, real estate aerial shooting, event panoramic recording
- Agricultural civilian monitoring: Farm crop growth inspection, orchard pest patrol, farmland water resource observation
- Ecological & environmental protection inspection: Forest vegetation monitoring, river surface pollution inspection, wetland wildlife observation
- Hobby & civilian aviation recreation: Large fixed-wing RC aircraft, light long-distance sightseeing civilian drones
Factory Production & Strict Quality Control
Our factory owns complete CNC precision machining workshops, independent UAV engine assembly lines and professional performance test benches. Every finished drone gasoline engine will pass the following full inspection before delivery:
- Raw material inspection: Aluminum alloy cylinder, crankshaft and carburetor material composition detection and dimensional calibration

- Continuous full-load running test for 1.5 hours, real-time monitoring power output, temperature, vibration and power generation stability
- Finished assembly inspection: Pipeline sealing test, ignition system stability test, fuel supply uniformity verification
- Final appearance & anti-rust protection inspection before packaging
Each UAV engine has an independent production serial number, all test data is archived to provide traceable quality guarantee for global wholesale and retail buyers.
Frequently Asked Questions
FAQ 1: What gasoline and lubricating oil should I use for this ZT-350cc UAV gasoline engine, and how to match the 25:1 mixing ratio correctly?
Answer: This drone gasoline engine requires high-purity non-ethanol unleaded gasoline above 95 octane, paired with special two-stroke aviation lubricating oil. The standard mixing ratio is 25 parts gasoline to 1 part lubricating oil. Ethanol-containing gasoline will generate a large amount of carbon deposits inside the cylinder, reduce engine power and damage the carburetor. Do not use low-octane leaded gasoline. Prepare mixed fuel strictly according to the ratio before each flight to avoid cylinder wear caused by insufficient lubrication.
FAQ 2: Can the ZT-350 UAV engine work normally at high altitude over 5000m, and is it compatible with hybrid VTOL drones?
Answer: Yes, this UAV engine is designed with a maximum service ceiling of 6000m, the air-cooled heat dissipation structure and adjustable fuel circuit can adapt to thin air at high altitudes without obvious power attenuation. It is fully compatible with medium-sized fixed-wing and light hybrid VTOL civilian drones, and supports the two standard propeller specifications of 30×12 and 32×10.
