Product Overview
The GTT70‑ISG UAV engine is a twin‑cylinder two‑stroke drone gasoline engine equipped with ISG integrated starter‑generator. This UAV gasoline engine is evolved from the base GTT70 platform, adding an all‑in‑one start‑generate module instead of discrete components.
Manufactured with aviation‑grade aluminum alloy via precision CNC machining, it uses air‑cooled fin‑style heat dissipation for continuous‑run outdoor missions. Under 24V/30A input, the ISG unit performs reliable electric starting; after ignition, it switches to generator mode and outputs DC24V 260W continuous power for onboard electronic devices. The independent ignition module supports DC 6V‑14.4V 1000 mAh power supply.
This drone gasoline engine is a practical power solution for civilian use‑cases including short‑range aerial mapping, farmland inspection and long‑endurance fixed‑wing patrol. It is designed exclusively for non‑military commercial‑grade applications. Custom‑tailored modification and development services can be provided upon client request.

Detailed Structural & Technical Features
ISG Integrated Starter‑Generator Module
This UAV gasoline engine integrates starter and generator into one compact ISG assembly. It executes electric start under 24V 30A power supply; once started, the unit switches seamlessly to generate DC24V 260W electricity. Compared with schemes using separate starter and generator, this drone gasoline engine reduces component count, saves installation space and simplifies aircraft wiring harness layout.
Twin‑Cylinder Air‑Cooled Carburetor Power Body
Based on horizontally‑opposed twin‑cylinder layout, the engine adopts mature carburetor fuel supply. Operators can adjust fuel‑air ratio mechanically on‑site. The air‑cooling fin structure guarantees stable thermal performance during long‑time continuous flight. Anti‑corrosion surface treatment enhances reliability under dusty and humid field conditions.
Dual‑Option Propeller Matching
Two groups of two‑blade propeller specifications are officially recommended: 23×8‑10 and 24×8‑10. Users can select suitable propellers according to aircraft take‑off weight and mission profile. Standard mounting holes fit most mainstream small‑and‑medium‑size civilian fixed‑wing airframes without heavy custom rework.
Custom‑Development Support
Besides standard configuration, this UAV engine supports customized development against customer‑specific requirements. Modifications can cover mechanical interface, electrical parameters and auxiliary structure to match special civilian UAV platform demands.
Civilian Commercial Application Scenarios
GTT70‑ISG 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 requiring onboard 24V power supply for payloads
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‑ISG UAV gasoline engine passes multi‑stage testing before shipment:
- Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft, ISG assembly and ignition‑system components.
- Dimensional tolerance calibration for semi‑finished mechanical parts.
- Continuous full‑load running test, verifying power output, ISG start‑generate switching performance, RPM stability and working‑temperature performance.
- Finished‑product assembly inspection: ISG 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 requirements apply to the GTT70‑ISG UAV gasoline engine, and what risks will improper fuel mixing bring?
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 forbidden. Ethanol will trigger heavy carbon accumulation inside cylinders and carburetor, accelerate component wear and shorten the service life of this UAV engine. Always prepare mixed fuel strictly before flight; insufficient lubricant will cause severe cylinder damage.
FAQ 2: What differences exist between GTT70‑ISG and base‑model GTT70? Can I use propellers outside the official recommended list?
Answer: Compared with basic GTT70, the GTT70‑ISG UAV gasoline engine adds an ISG integrated starter‑generator module, realizing electric start and DC24V 260W onboard power output, while total weight rises to 3005 g. We advise selecting propellers within official recommended specifications (23×8‑10, 24×8‑10 two‑blades). If you plan to use non‑standard propellers, please contact our technical team in advance for power‑matching evaluation to prevent engine overload damage.
