Detailed Structural & Technical Features
Light‑Weight Twin‑Cylinder Air‑Cooled Body
This UAV gasoline engine adopts horizontally‑opposed twin‑cylinder layout. The whole engine weighs only 1800 g, effectively reducing dead load for small‑size airframes. Multi‑piece cooling fins deliver efficient heat dissipation under continuous‑run conditions, supporting prolonged outdoor flight tasks. Anti‑corrosion surface treatment improves durability in dusty and humid field environments.
Wide‑Voltage Light‑Weight Ignition Module
The supporting ignition unit weighs just 160 g and accepts DC 6V‑14.4V power supply. This drone gasoline engine can cooperate with multiple common UAV battery packs without extra voltage conversion hardware, simplifying aircraft‑system integration work. It maintains reliable ignition performance under engine‑vibration conditions.
Carburetor Fuel‑Supply System
Equipped with mature carburetor assembly, the UAV engine realizes simple mechanical adjustment for fuel‑air ratio. It features low maintenance threshold and convenient field tuning, suitable for users who prioritize cost‑effectiveness and easy on‑site service.
Airframe and Propeller Compatibility
Optimized for 24×10 two‑blade propeller. Standard mounting hole positions fit most mainstream small‑size civilian fixed‑wing airframes. Users can finish installation without complicated custom modification work.
Civilian Commercial Application Scenarios
The GTT70 drone gasoline engine fits non‑military civilian industrial UAV projects:
- Short‑range aerial survey & mapping: local‑area terrain scanning and land‑resource recording
- Civilian agricultural monitoring: farmland crop observation and orchard patrol
- Long‑endurance fixed‑wing civilian drone missions for environmental inspection
- Small‑size cargo‑delivery and inspection‑oriented civilian UAV platforms
Packaging & Global Shipping
Standard Export Package: Shock‑absorbing foam inner padding + heavy‑duty export carton. All moving metal components are wrapped with anti‑rust paper to avoid oxidation during long‑distance cross‑border sea or air transportation.
International Trade Terms: Support EXW, FOB, CIF, DDP and other mainstream logistics solutions, cooperate with global freight partners for port‑to‑port or door‑to‑door delivery.
Custom Fumigated Wooden Case: Available for bulk wholesale orders to strengthen protection for ocean shipment.
Delivery Lead Time: Sample single‑unit orders shipped within 7 working days; mass‑production bulk orders take 12‑18 working days after deposit confirmation.
Factory Production & Strict Quality Control
Every finished GTT70 UAV gasoline engine passes multi‑stage testing before shipment:
- Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft and ignition‑system components.
- Dimensional tolerance calibration for semi‑finished mechanical parts.
- Continuous full‑load running test, verifying power output, RPM stability and working‑temperature performance.
- Finished‑product assembly inspection: ignition‑function test, carburetor status check, fuel pipeline leak‑tightness test.
- Anti‑rust treatment and final packaging inspection.
Each drone gasoline engine is assigned an independent serial number; all test records are archived for traceable quality guarantee for global buyers.
Frequently Asked Questions
FAQ 1: What fuel should be used for the GTT70 UAV gasoline engine, and what should be noted for the 35:1 mixing ratio?
Answer: This drone gasoline engine requires 92‑grade unleaded gasoline mixed with fully synthetic two‑stroke lubricating oil at a 35:1 ratio. Ethanol‑blended gasoline is prohibited; ethanol will cause heavy carbon deposits inside the cylinder and carburetor, shortening the service life of this UAV engine. Always prepare mixed fuel strictly before flight. Insufficient lubricant will lead to severe cylinder wear.
FAQ 2: Can I use propellers other than the recommended 24×10 two‑blade propeller for this engine? What kind of airframes is this engine most suitable for?
Answer: We recommend using the official‑specified 24×10 two‑blade propeller to achieve rated power output. If you intend to use non‑standard propeller sizes, please contact our technical team in advance for power‑matching evaluation to prevent engine overload damage. This UAV gasoline engine is optimized for small‑and‑medium‑size civilian fixed‑wing UAV platforms; it is widely used for mapping, agricultural monitoring and environmental‑inspection missions.
