Product Overview
The GT9‑PRO UAV engine is a miniature single‑cylinder two‑stroke carburetor drone gasoline engine built for lightweight civilian fixed‑wing platforms. This UAV gasoline engine adopts mature small‑displacement two‑stroke architecture with air‑cooled heat dissipation and carburetor fuel supply, focusing on ultra‑low weight, compact dimension and reliable high‑speed performance.
Constructed from aviation‑grade aluminum alloy through precision CNC machining, fin‑style air‑cooling keeps stable operating temperature during continuous running. The compact ignition unit accepts DC 6V‑14.4V 1000 mAh power input and fits most small‑UAV battery setups.
This drone gasoline engine is intended purely for non‑military commercial‑civil uses such as small‑scale aerial observation, educational UAV projects and light‑weight long‑endurance civilian aircraft. Custom modification solutions can be provided upon client request.

Detailed Structural & Technical Features
Miniature High‑Speed Two‑Stroke Power Assembly
This UAV gasoline engine features a small‑capacity single‑cylinder two‑stroke layout. It produces 1.2 HP peak output at high rotational speed, while keeping total engine weight down to 435 g. Its wide working RPM window of 2300‑13500 rpm accommodates take‑off, climb and cruise conditions for small‑size civilian fixed‑wing aircraft.
Air‑Cooled Heat Dissipation & Light‑Weight Ignition Module
Multi‑layer cooling fins realize effective passive heat dissipation for continuous operation. Anti‑corrosion surface treatment improves reliability under outdoor dusty or humid conditions. The ignition module is only 100 g and supports DC 6V‑14.4V wide‑voltage input, minimizing extra workload for small‑airframe electrical‑system design.
Carburetor Fuel‑Supply System
Fitted with a compact carburetor assembly. Operators can fine‑tune the fuel‑air ratio according to altitude and ambient temperature. Mechanical adjustment structure facilitates on‑site inspection, part replacement and maintenance in field environments.
Propeller Matching & Customization Support
Three sizes of two‑blade propellers (11×6, 11×7, 12×6) are officially recommended. Standard mounting interfaces adapt to most mainstream small civilian fixed‑wing airframes. Customized development is supported for projects with special technical requirements.
Civilian Commercial Application Scenarios
The GT9‑PRO drone gasoline engine applies to non‑military civilian industrial & hobby‑grade UAV projects:
- Light‑weight small‑platform aerial observation and short‑range aerial survey
- Educational UAV research‑and‑development projects and civilian flight‑testing platforms
- Small‑size long‑endurance civilian fixed‑wing aircraft requiring compact gasoline power
- Hobby‑grade large‑scale RC model aircraft
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 prevent 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 GT9‑PRO UAV gasoline engine goes through multi‑stage testing before delivery:
Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft, carburetor 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: carburetor‑status check, ignition‑function test, fuel‑pipeline leak‑tightness test.
Anti‑rust treatment and final packaging inspection.
Each drone gasoline engine carries an independent serial number; all test records are archived for traceable quality guarantee for global buyers.
Frequently Asked Questions
FAQ 1: What fuel‑mix ratio must be used for GT9‑PRO? What happens if I confuse it with other engine mixing ratios?
Answer: This drone gasoline engine strictly requires 92‑grade unleaded gasoline mixed with fully synthetic 2‑stroke lubricating oil at 25:1 volume ratio. Do not apply the 35:1 ratio used on larger‑displacement engines. Too‑little lubricant will cause severe cylinder wear and engine seizure; excessive oil will create heavy carbon deposits and foul spark plugs. Ethanol‑blended gasoline is prohibited. Always prepare mixed fuel before flight.
FAQ 2: Can I install propellers larger than the recommended sizes on GT9‑PRO? What risk will it bring?
Answer: We strongly advise you to use the officially recommended two‑blade propellers: 11×6, 11×7 and 12×6. Installing oversized propellers will overload the engine, cause excessive mechanical load, reduce maximum RPM, overheat components and shorten service life.
