GF60i2 twin‑cylinder 4‑stroke drone gasoline engine

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

Core Product Advantages

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

Stable Twin‑Cylinder Inline Four‑Stroke Layout
Dual‑cylinder balanced‑structure brings smoother power delivery, lower vibration and quieter running compared with single‑cylinder engines. The four‑stroke design realizes clean combustion, well‑adapted for long‑duration aerial‑camera shooting work.
Excellent Power Performance
The total displacement reaches 59.82cc, composed of two 29.91cc single cylinders. This twin‑cylinder gasoline engine can output peak power of 5.1 HP at 8000 rpm, offering ample power for medium‑size fixed‑wing aircraft take‑off, climb and high‑speed cruise.
Broad Working Speed Range
Its available operating rotational‑speed ranges 1200‑7500 rpm. The wide‑band speed adaptation meets multiple flight requirements, containing low‑speed long‑time cruising patrol, steady‑speed flight and high‑speed travel for aerial‑survey missions.
Optimized Weight‑Control Design
The main engine body weighs 2800g, and the separate ignition module weighs 160g. Compact and sturdy construction supports long‑time continuous operation, and reserves adequate installation space for airborne cameras and sensing equipment.
Two‑Blade Propeller Matching
It supports mainstream two‑blade propeller sizes 22×8‑10 and 23×8‑10. Users are able to replace propellers to adjust thrust, flying‑speed and overall flight endurance.
Adaptable Ignition System and Standard Fuel Proportion
The ignition assembly supports wide‑range DC 6‑14.4V 1000‑mAh power supply and keeps reliable ignition under complicated outdoor environments. Fuel mixture adopts the 35:1 ratio of 92‑octane unleaded gasoline and full‑synthetic two‑stroke lubricant for simple daily maintenance.

Product Overview

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

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

Balanced twin‑cylinder operation cuts vibration effectively, reducing camera shake and helping aerial devices capture crisp and clear‑definition footage.

2. Rotational‑Speed Characteristic and Thrust Adjustment

The practical usable speed scope is 1200 rpm‑7500 rpm, and the engine reaches its maximum 5.1‑horsepower output at 8000 rpm.

Two specifications of two‑blade propellers are optional. Operators can select matched propellers to carry out low‑speed patrol or high‑speed cruise flight.

3. Ignition Configuration and Fuel‑Mix Specification

The detachable ignition component weighs 160g and adapts to DC 6‑14.4V wide‑voltage power input. Its 1000‑mAh power supply delivers steady spark ignition in the whole flight course.

92‑grade unleaded gasoline needs mixing with full‑synthetic dedicated two‑stroke lubricating oil at 35:1. Mixed‑gas lubrication lowers the abrasion of internal moving components and extends engine service life during long‑hour continuous tasks. 发动机 (12).webp
