Product Overview
The GTT170‑E‑G UAV engine is a twin‑cylinder two‑stroke drone gasoline engine with factory‑fitted electric start and built‑in generator module, designed for civilian commercial unmanned aerial vehicles. This UAV gasoline engine is evolved from the GTT170‑E platform, adding an integrated generator function and reserving interfaces for optional EFI system retrofitting.
This drone gasoline engine adopts aviation‑grade aluminum alloy and precision CNC machining. The built‑in generator provides DC14V 250W continuous power supply for onboard sensors, mapping cameras and data transmission equipment, removing the burden of additional heavy onboard batteries. The reserved EFI modification interface allows users to upgrade to electronic fuel injection later when higher‑altitude working capacity is required.
Supporting customized configuration development, this UAV engine is a flexible, cost‑effective power option for medium‑size civilian industrial UAV projects such as aerial mapping and long‑endurance patrol. It is only for non‑military commercial applications.

Detailed Structural & Technical Features
Integrated Electric‑Start & 250W Generator Assembly
This UAV gasoline engine is equipped with a 24V electric starter for effortless automatic startup, no manual pull‑start required. The built‑in generator outputs stable DC14V 250W power during engine operation. It can continuously feed power to aerial survey cameras, monitoring sensors and communication modules, reducing extra battery weight inside drone cabin and simplifying the whole aircraft wiring layout of this drone gasoline engine.
Reserved Interface for Optional EFI Retrofit
Different from standard carburetor‑only UAV engine versions, GTT170‑E‑G reserves mounting interfaces for later‑installed EFI system. After retrofitting the electronic fuel injection kit, the engine can automatically adjust fuel injection volume based on altitude and ambient temperature, restraining power attenuation under high‑altitude thin‑air conditions. Users can choose to keep original carburetor configuration or upgrade EFI according to mission budgets and operating environments.
Light‑Weight Independent Ignition Module
The supporting ignition unit weighs only 170 grams, powered by DC6V‑14.4V 1000mAh power source. It delivers consistent spark performance under high‑vibration flight conditions. The modular‑designed ignition component can be inspected and replaced separately, users do not need to disassemble the main body of the drone gasoline engine for routine ignition‑system maintenance.
Twin‑Cylinder Air‑Cooled Heat Dissipation & Simple Installation
The two‑stroke twin‑cylinder air‑cooled cylinder block with dense heat‑dissipation fins ensures stable working temperature in long‑hour continuous flight. Aviation aluminum alloy main body has anti‑corrosion surface treatment to adapt dusty and humid outdoor operating environments. Standard mounting holes fit mainstream civilian fixed‑wing and hybrid VTOL airframes; it supports two‑blade propellers of 30×12 and 32×10, without complex custom machining.
Civilian Commercial Application Scenarios
This GTT170‑E‑G drone gasoline engine applies exclusively to non‑military civilian industrial UAV fields:
- Aerial survey & mapping: Medium‑range terrain scanning, land‑resource investigation, infrastructure construction progress monitoring
- Commercial aerial photography: Real‑estate aerial shooting, large‑landscape panoramic filming, outdoor event aerial recording
- Agricultural civilian inspection: Farm‑crop growth tracking, large orchard patrol, farmland resource monitoring
- Ecological environmental monitoring: Forest vegetation survey, river‑basin water‑environment inspection, wetland wildlife observation
- Long‑endurance hybrid VTOL & fixed‑wing civilian drone projects with high onboard power consumption demands
Packaging & Global Shipping
Standard Export Packing: Shock‑absorbing foam inner lining + heavy‑duty export carton. All moving metal components are wrapped with anti‑rust paper to avoid oxidation during long‑distance sea or air cross‑border transportation.
International Trade Terms: Support EXW, FOB, CIF, DDP and other mainstream cross‑border 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 for enhanced protection for ocean‑going shipment.
Delivery Lead Time: Sample single‑unit orders shipped within 7 working days; mass‑production bulk orders will be delivered within 12‑18 working days after deposit confirmation.
Factory Production & Strict Quality Control
Each finished GTT170‑E‑G UAV gasoline engine passes multi‑stage strict testing before delivery:
- Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft, starter, generator and ignition components.
- Dimensional tolerance calibration for semi‑finished mechanical parts.
- Full‑load continuous running test, verify power output, generator stability, starting performance and temperature data.
- Finished‑product assembly inspection: starter‑generator function test, ignition reliability check, fuel pipeline leak‑tightness test.
- Anti‑rust treatment and final packaging inspection.
Every drone gasoline engine is assigned an independent serial number, all test records are archived for traceable quality guarantee for global buyers. Custom‑modified units will carry extra test records for adjusted configurations.
Frequently Asked Questions
FAQ 1: What fuel should I use for GTT170‑E‑G UAV gasoline engine and how to maintain the 35:1 mixing ratio?
Answer: This drone gasoline engine requires 95‑grade unleaded gasoline mixed with fully‑synthetic two‑stroke lubricating oil at 35:1 proportion. Ethanol‑containing gasoline is forbidden, ethanol will produce heavy carbon deposits inside cylinders, damage carburetor and shorten the service life of this UAV engine. Always prepare mixed fuel strictly before flight. Insufficient lubricating oil will cause serious cylinder abrasion.
FAQ 2: Is the EFI retrofit kit sold separately? And can this engine work for hybrid VTOL civilian drones?
Answer: Yes, the EFI retrofitting kit can be purchased separately. You can keep the original carburetor configuration or upgrade EFI according to your actual high‑altitude mission requirements. This UAV gasoline engine is fully compatible with medium‑size hybrid VTOL and fixed‑wing civilian drones. Official recommended propellers are two‑blade 30×12 and 32×10.
