Performance Characteristic

This drone gasoline engine exhibits progressive thrust‑torque output within 1000‑6500 rpm working zone. Maximum tensile force reaches 48.4 kg, meeting thrust requirements for many medium‑size civil UAV platforms. The capacitor discharge ignition maintains stable combustion under variable working conditions. At 5500 rpm, the built‑in generator provides steady 350W DC14V power for onboard equipment. Stock carburetor version works reliably for general‑altitude missions; retrofitting EFI will optimize fuel delivery for high‑altitude locations. Wear‑resistant cylinder hardware guarantees consistent performance over long flight hours.

Application Scenarios

This compact 2‑stroke gasoline engine is well‑suited for multiple civil‑focused UAV projects:

Medium‑endurance commercial UAV platforms

Industrial mapping, inspection and monitoring drones

Light‑duty agricultural UAV power systems

Medium‑size 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 propeller suggestions do you have for the GTT324 UAV engine?

A: We recommend two‑blade propellers of 36×14, 36×16 and 39×12. Actual propeller selection should take your UAV’s total take‑off weight, expected cruise speed and typical working RPM into account for best efficiency.

What is the main benefit of capacitor discharge ignition on this drone gasoline engine?

A: Capacitor discharge ignition delivers powerful, consistent spark. It improves cold‑start performance, stabilizes engine idle, and helps maintain complete combustion across varying RPM, reducing misfire risks for long‑duration UAV flights.
