OPERATION (EC11-LINK)
・
Setting of the idling position by pulse width of PWM signal. The position of the throttle valve is usually
+50μs(+40μs
～
+50μs) from the fully close position.
・
This position, slightly open from the full close position is the reference
position. The throttle valve is automatically controlled by the ECU to hold
the idling rpm you have set when the throttle valve position is at idling
position, in case you use a transmitter, the throttle stick of the
transmitter is moved down to the bottom.
・
The mark on the throttle valve aligns with the mark at full open position
usually around 1850μs. Change the parameter to align each mark as
shown on the left.
・
Inputting extremely large value may cause damage to the throttle servo
creating excessive tension on the throttle linkage. So change the
parameter ±10μs or less at each adjustment.
・
In case the ECU could not hold the idling rpm and the engine stalls, add +5μs to the current parameter.
When the aircraft is diving with the throttle control signal at the idling position, in case you use a
transmitter, the throttle stick of the transmitter is moved down to the bottom, the propeller turns at
higher rpm than the set rpm at idling by airflow to the propeller created by the dive. In this case, the ECU
closes the throttle valve excessively until the engine stalls trying to reduce the propeller rpm. If it
happens, add +5μs to the parameter also.
・
In case the idling rpm doesn't decrease to the value you set in the prosess

, even if temperature of
the engine goes over 100
℃
, reduce the value by -5μs each time until the rpm decreases.

・
Setting of the idling rpm when the throttle stick of the transmitter is moved down to the bottom, or
throttle signal from your flight controller ordered the throttle valve to stay at idling position. The
parameter varies depending on your propeller choice and an aircraft. Although the rpm at idling depends
on propeller, the parameter is usually between 1600 and 2400 rpm. In case you input the parameter
beyond the range, the ECU controls the idling rpm between lower and upper limit. The ECU aim at the
idling rpm you have set once the engine is warmed up. But the idling rpm is slightly higher than the set
parameter when the engine is still cold.
・
Setting of the throttle valve position when you start the engine. To start the engine easier, the ECU
opens the throttle valve at this position even throttle signal from your flight controller ordered to close
more, in case you use transmitter, you move down the throttle stick of the transmitter and close the
throttle valve more than this position. Parameter is to be set 0%
