Throttle Setting
1.The throttle can be controlled by the receiver or the flight controller of the UAV. The power supply of the
throttle servo is provided by the receiver or the flight controller. The voltage range is 6V-7.4V.
Before using the engine, you need to adjust the pulse width of the throttle channel to make the
throttle opening in the correct range.Incorrect throttle settings, such as rudder suffocated, or
excessive throttle stroke, will cause the engine to work abnormally or even be damaged.
2. The EFI system does not require an additional special flameout switch. When the throttle valve is fully
closed, the engine will stop and turn off, and the power to the oil pump will be cut off at the same time.
