inline twin‑cylinder inspection aircraft motor

GF60i2 59.82cc Twin‑Cylinder Four‑Stroke Gasoline UAV Engine

Core Product Advantages

The GF60i2‑E is an inline twin‑cylinder four‑stroke gasoline power unit with built‑in electric start, designed as a balanced‑output medium‑size fixed‑wing RC aircraft motor and reliable civilian‑grade UAV engine. It is suitable for medium‑scale hobby aircraft, long‑time aerial‑photography unmanned planes and medium‑load inspection drones. Its key advantages are listed below:

Twin‑Cylinder Inline Four‑Stroke Structure
The dual‑cylinder balanced design delivers smoother power delivery, lower vibration and quieter operation compared with single‑cylinder engines. The four‑stroke layout supports stable long‑duration flight performance, making it well‑suited for aerial camera shooting and inspection tasks.
Convenient Electric Start System
The integrated electric starter simplifies engine starting procedures and helps reduce manual operation effort during field use. It supports reliable starting performance under complex outdoor conditions, which is beneficial for repeated daily flights and aerial survey missions.
Stable Power Output
With a total displacement of 59.82cc, composed of two 29.91cc single cylinders, this twin‑cylinder gasoline engine delivers a peak power of 5.1 HP at 8000 rpm. It provides sufficient thrust for medium‑size fixed‑wing aircraft take‑off, climb‑out and high‑speed cruise.
Wide Operating Speed Range
The usable RPM range covers 1200–7500 rpm. This broad speed bandwidth adapts to multiple flight scenarios, including low‑speed long‑time cruising patrol, steady medium‑speed flight and high‑speed aerial survey travel.
Practical Weight and Installation Design
The main engine body weighs 3025g, and the separate ignition module weighs 160g. The compact and sturdy construction supports long‑time continuous operation while reserving adequate installation space for airborne cameras and sensing equipment.
Standard Fuel and Ignition Configuration
The ignition assembly supports a wide‑range DC 6V–14.4V 1000mAh power supply for dependable spark ignition in outdoor environments. The recommended fuel mixture is 35:1, using 92‑octane unleaded gasoline and full‑synthetic two‑stroke lubricant for routine maintenance.

Product Overview

1. Product Positioning for Medium‑Sized Civil Fixed‑Wing Unmanned Aircraft

GF60i2‑E is an air‑cooled inline twin‑cylinder four‑stroke piston‑type gasoline engine with electric start. Compared with single‑cylinder GF‑series engines, the dual‑cylinder structure improves operation smoothness and power stability. It is suitable for medium‑size RC hobby aircraft, medium‑load aerial‑photography drones and short‑to‑medium‑range inspection unmanned aerial vehicles.

The balanced twin‑cylinder operation effectively reduces vibration, which helps lower camera shake and supports aerial equipment in capturing clearer high‑definition footage.

2. Electric Start and Thrust Performance

The built‑in electric start mechanism allows more convenient engine startup, especially in outdoor operation scenarios where manual starting may be inconvenient. This design helps improve daily usability and supports consistent flight preparation workflows.

The practical usable speed range is 1200 rpm–7500 rpm, and the engine reaches its maximum 5.1‑horsepower output at 8000 rpm. Users can select suitable propeller specifications to adjust thrust, flying speed and flight endurance according to different mission requirements.

3. Ignition Configuration and Fuel‑Mix Specification

The detachable ignition component weighs 160g and supports DC 6V–14.4V wide‑voltage power input. Its 1000mAh power supply helps maintain stable spark ignition throughout the flight.

92‑octane unleaded gasoline should be mixed with full‑synthetic dedicated two‑stroke lubricating oil at a ratio of 35:1. Proper fuel mixing reduces wear on internal moving components and helps extend engine service life during long‑hour continuous tasks. 发动机 (12).webp
