Product Overview
The GTT70‑E UAV engine is a twin‑cylinder two‑stroke drone gasoline engine with built‑in electric‑start function, derived from the standard GTT70 UAV gasoline engine platform. It adds a gear‑driven electric starter to realize electric ignition while retaining the original power performance of the base engine.
Constructed from aviation‑grade aluminum alloy and processed by precision CNC machining, the engine adopts air‑cooled fin‑type heat dissipation structure to guarantee stable thermal performance under long‑time continuous flight conditions. The starter system is powered by a 12V (3S lithium battery recommended) power source. The supporting ignition module accepts DC 6V‑14.4V 1000 mAh power input, offering flexible compatibility with common civilian‑drone battery systems.
This drone gasoline engine is well‑suited for civilian‑oriented scenarios including short‑range aerial mapping, farmland crop monitoring and long‑endurance fixed‑wing environmental patrols. It is designed purely for non‑military commercial‑grade applications.

Detailed Structural & Technical Features
Gear‑Driven Electric‑Start Assembly
This UAV gasoline engine is fitted with a reliable gear‑reduction electric‑start module. Under 12 V power supply (3S lithium battery recommended), the starter drives the crankshaft through gear sets to finish automatic ignition. This drone gasoline engine removes tedious manual‑starting work, which is helpful for frequent field‑mission operations. The starter‑gear structure is optimized for shock resistance to adapt to vibration during engine operation.
Horizontally‑Opposed Twin‑Cylinder Air‑Cooled Power Body
Based on mature horizontally‑opposed twin‑cylinder layout, the engine uses carburetor fuel supply. Operators can complete mechanical fuel‑air‑ratio tuning on site. Multi‑group cooling fins realize efficient heat dissipation during continuous running. Anti‑corrosion surface treatment improves component durability under dusty and humid outdoor working environments.
Wide‑Voltage Light‑Weight Ignition Module
The supporting ignition unit weighs merely 160 g and supports DC 6V‑14.4V power input. It can match various common UAV battery packs without extra voltage‑conversion hardware, simplifying the electrical‑system integration work of the whole aircraft. Stable ignition performance is maintained under engine vibration conditions.
Airframe and Propeller Compatibility
Optimized for 24×10 two‑blade propeller. Standard mounting‑hole positions fit most mainstream small‑and‑medium‑size civilian fixed‑wing UAV airframes; users can complete installation without heavy custom modification work.
Civilian Commercial Application Scenarios
The GTT70‑E drone gasoline engine applies to non‑military civilian industrial UAV projects:
- Short‑range aerial survey & mapping: regional terrain scanning and land‑resource data collection
- Civilian agricultural monitoring: crop‑growth observation and orchard‑patrol tasks
- Long‑endurance fixed‑wing environmental inspection for forest and water‑area monitoring
- Small‑size civilian inspection UAV platforms that require convenient electric‑start function
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‑E UAV gasoline engine passes multi‑stage testing before shipment:
- Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft, electric‑starter assembly and ignition‑system components.
- Dimensional tolerance calibration for semi‑finished mechanical parts.
- Continuous full‑load running test, verifying power output, electric‑start reliability, RPM stability and working‑temperature performance.
- Finished‑product assembly inspection: electric‑start‑function test, 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 specifications are required for GTT70‑E UAV gasoline engine? What damage will wrong fuel mixing cause?
Answer: This drone gasoline engine must use 92‑grade unleaded gasoline mixed with fully synthetic two‑stroke lubricating oil at a 35:1 ratio. Ethanol‑blended gasoline is prohibited. Ethanol will produce heavy carbon deposits inside cylinders and carburetor, accelerate part wear and shorten the service life of this UAV engine. Please prepare mixed fuel strictly before flight; insufficient lubricant will lead to serious cylinder‑scuffing failure.
FAQ 2: What is the difference between GTT70‑E and standard GTT70? Can I use a power‑supply other than the recommended 3S lithium battery for starting?
Answer: Compared with the manual‑start GTT70, the GTT70‑E UAV gasoline engine adds a gear‑driven electric‑start assembly, bringing convenient electric‑start function, while the total engine weight rises to 2470 g. The starting system is rated for 12 V input, and a 3S lithium battery is officially recommended. If you select other power sources, please ensure stable 12 V output and sufficient current capacity; improper power supply may cause starter failure or damage.
