Performance Characteristic
This UAV engine has a broad usable speed scope of 1000‑7000 rpm. It delivers maximum 40HP power at 7000rpm. The built‑in generator supplies steady DC14V 350W power for airborne devices. The stock carburetor setup performs reliably for most medium‑altitude civil drone missions. After retrofitting EFI system, it gains better fuel atomization and high‑altitude working capability. The wear‑proof cylinder structure ensures consistent power output during repeated and long‑duration UAV flight cycles.
Application Scenarios
This compact 2‑stroke gasoline engine fits multiple civil‑oriented application cases:
Medium‑payload commercial UAV platforms
Long‑endurance industrial inspection & mapping drones
Agricultural operation 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 kind of payload power can the GTT400 drone gasoline engine support?
A: Its integrated generator offers DC14V 350W output. It is suitable for low‑power airborne devices including survey cameras, short‑range sensors and signal transmission modules. For high‑power payloads, external auxiliary power modules will be required.
What differences will EFI retrofit bring to this UAV engine?
A: The original carburetor version is cost‑effective and easy to maintain for conventional working conditions. After installing the optional EFI kit, the engine achieves improved fuel efficiency, smoother idle performance and more stable power output when flying at high altitudes or under drastic temperature changes.
