GT35‑ISG 34.96cc Integrated‑Start‑Generator 2‑Stroke UAV Gasoline EngineGT35‑ISG 34.96cc Integrated‑Start‑Generator 2‑Stroke UAV Gasoline Engine

Core Product Advantages

This GT35‑ISG serves as an integrated‑starter‑generator UAV engine, power‑generating drone gasoline engine and multi‑functional UAV gasoline engine built for medium‑sized civilian fixed‑wing aircraft, long‑endurance survey‑grade unmanned aircraft and small‑scale hybrid‑power aerial devices. Its key advantages are listed below:
  1. All‑in‑One Starter‑Generator Integrated‑Structure

    The built‑in ISG component combines electric starting and power‑generation capacity. It supports 24‑V 30‑A startup and provides DC24V‑260‑watt stable power supply for airborne equipment, removing the need for an extra independent generator unit.

  2. Stable Powerful Power Output

    With 34.96‑cc displacement, the two‑stroke gasoline engine delivers peak power of 4.2 HP at 8800 rpm, offering sufficient thrust reserve for medium‑size civilian unmanned‑aircraft take‑off, climbing and cruising flight.

  3. Broad Stable‑Speed Operating Range

    It steadily operates within 1500‑8000 rpm. The wide‑band rotational‑speed range accommodates low‑speed hovering, medium‑speed patrol and high‑speed flight for diverse civilian aerial‑operation scenarios.

  4. Rich Two‑Blade‑Propeller Adaptability

    Three mainstream propeller sizes are supported:18×10,19×8‑10 and 20×8. Operators can swap propellers to adjust thrust, flight speed and airborne power‑supply runtime.

  5. Wide‑Voltage Ignition System and Mature Fuel Matching

    The separate ignition module runs on DC 6V‑14.4V 1000mAh power source. It maintains reliable spark ignition in complicated outdoor environments. The fuel‑oil mixing ratio is fixed at 35:1 with regular gasoline and full‑synthetic two‑stroke lubricant.

  6. Compact Integrated Layout

    Though equipped with the starter‑generator assembly, the whole‑machine weight stays 1525g, keeping a favorable power‑to‑weight ratio for medium‑size drone airframes.

1. Product Positioning for Long‑Endurance Powered Civilian Unmanned Aircraft

GT35‑ISG is an air‑cooled two‑stroke piston‑type UAV gasoline engine fitted with an integrated starter‑generator module. It is upgraded on the basis of the standard GT35/35R power plant. This engine targets medium‑size fixed‑wing unmanned aircraft, long‑time aerial‑survey drones and small hybrid‑power civilian flying equipment.

Apart from supplying flight thrust, it is capable of self‑starting and outputting direct‑current power to sustain cameras, sensors and other onboard electronic gear, which is ideal for missions requiring extended air‑time.

2. Flexible Rotational‑Speed Performance and Built‑In Power‑Generation Function

The usable rotational‑speed range spans 1500 rpm‑8000 rpm. The engine hits its maximum 4.2‑HP power at 8800 rpm.

Its ISG assembly adopts 24 V, 30 A starting parameters for convenient electric startup. During operation, it steadily outputs 260‑watt DC‑24‑volt electricity to feed onboard devices. Multiple‑size two‑blade propellers allow users to customize flight thrust and speed.

3. Reliable Ignition System and Standard Lubrication Requirement

The detachable ignition component weighs 100 g and accepts DC 6V‑14.4‑volt power supply. The 1000‑mAh power unit guarantees consistent ignition sparks during the whole flight.

Fuel needs to be blended from ordinary civilian unleaded gasoline and full‑synthetic two‑stroke lubricating oil under the mixing ratio of 35:1, which lowers the wear of internal moving parts for long‑hour operation.9.webp

Frequently Asked Questions (FAQ)

Q1: What civilian unmanned‑aircraft projects fit the GT35‑ISG UAV gasoline engine?

A1: This integrated starter‑generator drone gasoline engine suits medium‑sized fixed‑wing unmanned planes, long‑endurance aerial‑survey drones and hybrid‑power civilian flying craft. Its built‑in power‑generation function can supply electricity for cameras and airborne sensors. It is not intended for large‑scale heavy‑lift cargo‑carrying industrial‑grade UAVs.

Q2: What fuel‑oil mixing ratio should I follow and what is the function of the ISG module?

A2: You must mix regular unleaded gasoline and full‑synthetic two‑stroke lubricant strictly at 35:1. The ISG unit handles electric engine startup and outputs 24‑volt direct‑current power to feed onboard electrical equipment. You can refer to the user manual for fuel‑mixing steps and propeller‑matching guidance.
