Product Overview
GTT170 is a 170cc two‑cylinder air‑cooled 2‑stroke drone gasoline engine designed for small‑to‑medium civil UAV applications. Thanks to its ultra‑light main body and standalone lightweight ignition system, it minimizes total propulsion‑system weight. The air‑cooled design eliminates water‑cooling accessories, simplifying airframe layout. It outputs solid horsepower and tensile force, making it well‑suited for aerial survey, inspection and other medium‑load civil drone use‑cases. Custom‑tailored development is available to meet unique mechanical and system integration demands.

Performance Characteristic
This air‑cooled drone gasoline engine reaches peak power at 7500 RPM, generating 36 kg tensile force to support take‑off and climb for small‑medium UAVs. The broad 1200‑8000 rpm working range provides flexible tuning for different cruise speeds. Its independent ignition module accepts wide‑range DC input, bringing convenience for UAV electrical architecture. Without water‑cooling components, the whole power system stays light and compact. Proper air flow cooling must be ensured on airframe design side for sustained high‑power operation.
Application Scenarios
This compact air‑cooled 2‑stroke gasoline engine fits a variety of civil‑focused UAV projects:
Small‑to‑medium medium‑endurance commercial UAV platforms
Aerial mapping, site inspection and monitoring drones
Light‑duty agricultural UAV power systems
Compact civil drone system integration
Custom light aviation power projects
Customized development service is available. We can adjust parameters, mounting interfaces and auxiliary structures according to customer‑specific integration requirements.
FAQ
What cooling consideration should I take for the GTT170 air‑cooled UAV engine?
A: Since it is air‑cooled, sufficient directed airflow must be reserved in your UAV frame design. Blocked airflow will cause overheating and power drop during long‑time high‑power flight.
What power source is suitable for the ignition system of GTT170 drone gasoline engine?
A: The ignition module requires DC6V‑14.4V input with at least 1000mAh capacity. You can select matching lithium battery according to your UAV’s existing power architecture to keep stable ignition supply.
