Installation and Start

Hardware Installation 

1.Please do not install the ECU on the engine or the engine bracket, because the violent vibration during 
work can easily cause damage to the hardware. Please install the ECU in the place with the slightest 
vibration inside the aircraft;

2.Please refer to the wiring diagram to ensure the correct connection of the EFI system cable;

3.When the engine is installed on the fuselage, check that the connecting cables are connected correctly 
and the reliability of the cable connection. At the same time, it is necessary to make sure the wires do not 
rub against the body parts;

4.When the engine is installed on the fuselage, corresponding shock absorption is required, and screw glue 
is used to ensure reliable installation; 

5.Connect the thin oil pipe from the output port of the oil pump to the oil inlet of the throttle valve, and tighten 
the blue screw of the oil inlet. There should be no bends in the oil pipe to ensure a smooth oil path;

6.The oil pump is installed close to the oil tank, it is recommended not to be higher than the oil level, and to 
ensure that the oil inlet pipe and the oil outlet pipe will not bend; 

8.Install the oil filter between the oil pump inlet and the oil tank;Install the oil filter between the oil pump inlet 
and the oil tank, confirm that the oil pipe is connected in place, and the oil pipe anti-falling nut is locked;

9.It needs to use 3S lipo battery (12.6V) to supply power. The 2000mA/h battery can supply power for the 
engine to run continuously for two hours (5000 rpm).
