GT25 25.09cc 2‑stroke UAV gasoline engine

GT25 25.09cc Compact 2‑Stroke UAV Gasoline Engine

Core Product Advantages

This GT25 model is a mid‑size lightweight UAV engine, high‑performance drone gasoline engine and reliable UAV gasoline engine designed for hobby‑level RC aircraft, small‑size fixed‑wing civil unmanned planes and lightweight aerial‑survey drones. Its prominent strengths are listed below:

Moderate‑Displacement Design With Ample High‑Speed Power Reserve
With 25.09‑cc displacement, the two‑stroke engine delivers peak power of 2.97 HP at 11000 rpm. It supplies strong power‑backup for fast‑speed cruising, steep climbing and rapid take‑off of small‑sized civil unmanned aerial vehicles.
Broad Adjustable Working‑Speed Band
Stable operation is supported across the 1800‑11000‑rpm range. The wide‑band speed output meets multiple flight modes, including low‑speed cruise, medium‑speed hovering and high‑speed fast flight.
Well‑Balanced Light‑Weight Structure
The main engine body weighs only 840 g, paired with a 100‑gram independent ignition module. The light‑weight layout saves aircraft weight budget, leaving extra loading capacity for airborne cameras and sensing equipment.
Rich Compatibility for Multiple Two‑Blade Propeller Sizes
It fits mainstream two‑blade propeller specifications: 16×8, 16×10, 17×8 and 17×10. Operators can freely swap propellers to adjust thrust, flight velocity and flight duration according to actual mission demands.
Wide‑Voltage Adaptable Ignition System
The matched ignition component works steadily under DC 6V‑14.4V power supply with a 1000‑mAh power source. It delivers consistent spark ignition under complicated outdoor environments and reduces unexpected flame‑out risk.
Easy Fuel Preparation and Low‑Cost Routine Maintenance
This drone gasoline engine runs on common civilian gasoline mixed with fully‑synthetic two‑stroke lubricating oil. The fixed fuel‑oil mixing ratio is 25:1. Daily maintenance only contains regular component inspection and fuel preparation without complex professional tuning.

Product Overview

1. Product Positioning for Light‑Duty Civilian Unmanned Aircraft

GT25 is a high‑quality air‑cooled two‑stroke piston‑type UAV gasoline engine. Positioned between tiny 16.91‑cc GT17‑PRO motor and large‑displacement industrial power units, it serves small‑size fixed‑wing RC aircraft, lightweight hobby drones, short‑range aerial‑photography unmanned planes and civilian practice‑grade flying equipment.

It balances light‑weight property and strong power output, which is the perfect power option for users who need faster flight speed and stronger thrust than miniature drone engines.

2. Wide‑Range Rotational Speed and Outstanding High‑Speed Performance

The usable rotational‑speed range covers 1800 rpm‑11000 rpm. The flexible speed window adapts to all routine flight conditions for small civil aircraft. When reaching the maximum speed of 11000 rpm, the UAV engine reaches its peak power of 2.97 HP, bringing excellent acceleration and climbing‑up performance.

Four types of two‑blade propellers are supported. Different propeller configurations help users prioritize long‑endurance hovering or fast‑speed cruising flight.

3. Stable Ignition Assembly and Standard Lubrication Specification

The separate ignition module weighs 100 g. It accepts wide‑range direct‑current power input from 6 V to 14.4 V, and the 1000‑mAh power supply guarantees steady ignition sparks during the whole flight process.

For fuel configuration, regular civilian gasoline needs to be blended with full‑synthetic 2‑stroke dedicated lubricating oil at the ratio of 25:1. Well‑mixed fuel can effectively reduce the abrasion of internal moving parts when the drone gasoline engine runs under high‑speed working conditions. 发动机 (2).webp

Frequently Asked Questions (FAQ)

Q1: Which kinds of civilian unmanned aircraft can the GT25 UAV engine be applied to?

A1: This lightweight drone gasoline engine fits hobby‑level fixed‑wing RC aircraft, compact aerial‑photography drones and small‑size civil practice flying machines. It is suitable for low‑altitude landscape shooting, short‑distance air observation and aircraft performance testing. It is not designed for heavy‑lift industrial cargo‑carrying UAV platforms.

Q2: What fuel‑oil blending ratio should I use and how do I raise the flight speed of my drone?

A2: You need to mix ordinary unleaded gasoline and full‑synthetic two‑stroke lubricating oil strictly at 25:1. You can switch between different sizes of two‑blade propellers to adjust flight speed and thrust. Special aviation fuel is not required. Complete blending guidance and propeller‑matching suggestions are placed inside the attached user manual.
