Press the (right hand button (+)) to confirm that you
really want to program the radio. The screen will
change to:
On your transmitter, raise first the trim to full, and
next the throttle stick to full, in this order.
Ensure stick is firmly against the stop.
Now holding the stick against the stop, press the
right button (+) to store the signal from your TX
into the ECU.
The screen will now change to:
Move the trim to low (or switch the “engine cut” switch to On) and throttle stick
back to zero and again press the right hand button (+).
The display will now change to:
Leaving the throttle stick in the minimum position,
raise the throttle trim to the full up position or
switch “Engine Cut” switch to off, and again press
the “+” button to store the Idle position into the
ecu.
If you have done all steps correctly the blue LED
in the ecu will light up flashing 2 times in the ECU
when the “Idle” command is received, meaning
that trim and throttle stick are set to idle positions
on the transmitter. Lower your throttle trim and
the LED will change to a single flash sequence
indicating correct reading of the transmitter engine
shut off signal by the ecu.
On some Futaba transmitters, it has been found that the throttle channel the sense of movement
may require reversing (Servo reverse) and to repeat the transmitter alignment.
The correct adjustment of the throttle adjustment on the ecu
can be verified in the second screen of the data terminal, the
percentage of the throttle position should read 0% at the
position of engine stop (trim and stick down), 100% with
stick/trim full up and between 10% and 30% at idle.
This now completes your radio setup and should only need doing again if the radio settings are
changed.
