Futaba GV-1 - Manual (Page 37)

FUNCTIONS
Mixture servo operation mode MxMD
The mixture servo must operate in proportion to operation of the throttle
servo. When a governor is used, the throttle servo is controlled by the gover-
nor. Therefore, the governor must generate the mixture signal.
The mixture operation mode can be selected.
When the "Gov" mixture servo operation mode is selected, the mixture servo
operates on a 9-point curve set by the governor. Set the rate of each point with
the "mixture rate set-up" function.
The "Dir" mode sets the curve at the transmitter in the governor off state to
simplify mixture curve setting. It is used by setting the transmitter fuel mix-
ture control function to "ACT". The curve data set at the transmitter controls
the mixture servo. The mixture servo can be operated by copying the mixture
curve. The AUX (m.trm) connector connects to the mixture channel. The set-
ting of each point is called from the transmitter with the "mixture rate set-up"
function. In this mode, curve data from the transmitter can be set for nine
points.
The "Dir" mode is used in mixture curve initial setting. Since operation is
linked with the throttle stick and not with the governor, after curve setting,
switch to the "Gov" mode. Not all Futaba transmitters have Fuel Mixture
Function (FMC), however it is not necessary since the GV-1 has a mixture
control function.
