GF150R5 149.55cc 5‑Cylinder Radial 4‑Stroke Gasoline UAV Engine

Core Product Advantages

The GF150R5 is a five‑cylinder radial‑type four‑stroke gasoline power‑unit, smooth‑running large‑size fixed‑wing RC aircraft motor and high‑power civilian‑grade UAV engine, designed for large‑scale hobby aircraft, long‑time aerial‑photography unmanned planes and heavy‑load inspection‑drones. Its key advantages are listed below:
  1. Unique 5‑Cylinder Radial Four‑Stroke Design

    Radial multi‑cylinder structure delivers steady power output, outstanding operation balance and low‑amplitude vibration. The four‑stroke layout brings quiet and clean‑burning performance, well‑suited for long‑duration aerial shooting missions.

  2. Powerful and Stable Thrust Output

    Combined displacement reaches 149.55cc, assembled with five sets of 29.91cc single‑cylinder assemblies. This radial gasoline engine provides peak power of 8.2 HP at 6500 rpm, enough power for large‑sized fixed‑wing aircraft take‑off, climbing and high‑speed cruising.

  3. Mature Wide‑Range Speed Adaptability

    Its stable working RPM covers 1000‑6500 rpm. The adjustable rotational‑speed range adapts to low‑speed long‑time cruising patrol, medium‑speed stable hovering and high‑speed cross‑country flight under multiple aerial‑operation scenarios.

  4. Reliable Structural Layout

    The whole engine weighs 4600g and the independent ignition module weighs 430g. The sturdy radial‑type structure can bear heavy‑duty long‑time operation and reserve sufficient payload space for professional airborne cameras and multi‑functional sensing devices.

  5. Flexible Propeller Compatibility

    It supports multiple sizes of two‑bladed and three‑bladed propellers. Optional specifications contain 26×16, 28×14, 30×12 for two‑blade propellers and 23×16, 26×14 for three‑blade propellers. Users are allowed to match propellers to adjust thrust, flying‑speed and flight endurance.

  6. Standard Fuel‑Oil Matching and Wide‑Voltage Ignition System

    The dedicated ignition module works steadily under DC 7.4V‑12.6V 1000mAh power supply, delivering dependable spark‑ignition performance in complex outdoor environments. The fuel adopts a 35:1 mixing‑ratio of 92‑octane unleaded gasoline and full‑synthetic two‑stroke lubricant for convenient daily maintenance.

Product Overview

1. Product Positioning for Large‑Scale Civil Fixed‑Wing Unmanned Aircraft

GF150R5 is an air‑cooled five‑cylinder radial four‑stroke piston‑style gasoline engine. Different from single‑cylinder GF‑series power units, this multi‑cylinder radial engine focuses on balanced power output, low vibration and high‑power performance. It is well‑suited for large‑size RC hobby aircraft, high‑load aerial‑photography drones and long‑range inspection unmanned aerial vehicles.

Multi‑cylinder balanced operation greatly cuts running vibration, effectively avoiding image blur and assisting professional camera equipment to acquire sharp aerial footage.

2. Rotational‑Speed Characteristic and Thrust Adjustment

The practical working‑speed range runs 1000 rpm‑6500 rpm. The engine can reach the maximum 8.2‑horsepower power at 6500 rpm.

Both two‑blade and three‑blade propeller choices are available. Operators can switch different propeller sizes to achieve low‑speed long‑time patrol or fast‑speed cross‑country cruise flight.

3. Ignition Configuration and Fuel‑Mix Specification

The independent ignition component weighs 430g and supports DC 7.4V‑12.6V wide‑range power supply. Its 1000‑mAh power source keeps stable spark‑ignition output throughout the whole flight.

Ordinary 92# unleaded gasoline needs to be blended with full‑synthetic two‑stroke dedicated lubricating oil under the mixing‑proportion 35:1. Mixed fuel lowers abrasion of internal moving parts and extends engine service life for continuous long‑hour tasks.发动机 (1).webp
