FAQ

A:

Choosing the right engine depends on your UAV’s maximum takeoff weight, required power, endurance target, installation space, and operating environment. Please share these requirements when making an inquiry so that a suitable engine model can be evaluated.

A:

Specifications vary by model. When comparing engines, please check rated power, engine weight, and fuel consumption under the specified operating conditions. Include your application requirements in your inquiry to request the relevant model specifications.

A:

Fuel and lubricant requirements depend on the engine model. Always follow the product manual for fuel grade, lubricant specifications, and mixing ratio where applicable. Confirm these requirements before operation, as unsuitable fuel or lubrication may damage the engine.

A:

We provide a stable after-sales warranty for all finished starter motors and formal spare parts. Under normal installation and working conditions, our products feature low failure rate and long service life.
