GF30 29.91cc four‑stroke drone gasoline engine

GF30 29.91cc 4‑Stroke Gasoline UAV Engine

Core Product Advantages

The GF30 is a compact lightweight four‑stroke gasoline power‑unit, low‑vibration fixed‑wing RC airplane motor and reliable civilian‑grade UAV engine, designed for small‑size hobby aircraft, aerial‑photography unmanned planes and lightweight inspection‑drones. Its key advantages are listed below:

Optimized Four‑Stroke Structure
Four‑stroke piston‑type construction brings smoother running, less vibration and quieter operation compared to 2‑stroke motors, which is perfect for aerial shooting missions that demand stable platform performance.
Stable and Light‑Duty Thrust Performance
With 29.91‑cc displacement, this gasoline engine delivers peak power of 2.68 HP at 9000 rpm, providing sufficient thrust for take‑off, climb‑out and high‑speed cruise of small‑sized fixed‑wing aircraft.
Wide Usable Speed Range
Its stable working RPM covers 1600‑8000 rpm. The broad rotational‑speed bandwidth adapts to low‑speed cruising patrol, medium‑speed hovering and high‑speed flight under multiple aerial‑operation scenarios.
Ultra‑Light‑Weight Body Design
The main engine body weighs only 1160g and the separate ignition module weighs 100g. The lightweight structure leaves ample payload capacity for airborne cameras and sensing devices.
Multiple Two‑Blade Propeller Compatibility
Three common propeller sizes are supported:15×10, 16×8‑10 and 17×6‑10. Users are able to swap propellers to adjust thrust, flight speed and flight endurance for different tasks.
Mature Ignition System and Standard Fuel‑Oil Matching
The independent ignition module accepts wide‑voltage DC 6V‑14.4V 1000mAh power supply for dependable spark ignition in complicated outdoor environments. It uses a 35:1 mixing‑ratio of 92‑octane gasoline and full‑synthetic two‑stroke lubricant for convenient routine maintenance.

Product Overview

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

GF30 is an air‑cooled four‑stroke piston‑style gasoline engine for UAV. Distinct from our two‑stroke GT‑series power plants, this four‑stroke engine prioritizes low‑vibration, low‑noise and steady running performance. It is well‑suited for compact RC hobby aircraft, lightweight aerial‑photography drones and short‑range inspection unmanned aerial vehicles.

The reduced‑vibration running condition effectively cuts motion blur and helps airborne camera equipment capture crisp photographs.

2. Rotational‑Speed Characteristic and Thrust Adjustment

The practical working‑speed range runs 1600 rpm‑8000 rpm. When the motor reaches 9000 rpm, it outputs the maximum 2.68‑horsepower power.

Three kinds of two‑blade propellers are optional. Operators are allowed to match different propeller specifications to realize low‑speed long‑time patrol or fast‑speed cruise flight.

3. Ignition Configuration and Fuel‑Mix Specification

The detachable ignition component weighs 100g and supports DC 6V‑14.4V wide‑range power supply. Its 1000‑mAh power source maintains stable spark output through the whole flight.

Ordinary 92# unleaded gasoline must be blended with full‑synthetic two‑stroke dedicated lubricating oil under the mixing‑proportion 35:1. Mixed fuel reduces wear on internal moving components and prolongs engine service life for long‑hour continuous‑running tasks. 发动机 (38).webp
