3.2. Starting your turbine
Be sure to have a fire extinguisher (CO2) within reach.
The ECU runs through an automated calibration routine to
adjust fuel metering to outside air parameters as well as tube
length. The Hornet III ECU, does this routine at every start.
On the first boot-up the ECU will adjust the temperature probe
and the pump's starting voltage.
The turbine is then ready for start (green I/O LED ON ).
Set trim to max, then throttle to max. The terminal will indicate
"STANDBY". The ECU is waiting for your order to start ( red I/O
LED ON ).
Simply retard throttle stick to minimum and within three seconds
to full.
The starting sequence will run. See the Pro Jet instructions (page
26).
Note that during the sequence, the turbine will calibrate for idle
and mid rev at ca. 60 000 rpm. Hold or adjust your model for this
procedure. The procedure can be interrupted any time using
emergency stop
by pulling the trim and throttle stick in the aft
position.
After that auto calibration routine, the turbine can be controlled
with the throttle ( red I/O LED OFF ).
All the parameters necessary for the turbine's safe operation
are now controlled by the ECU.
Conduct a test run of your turbine, possibly while testing the
range of your model.
Shut off the turbine at mid rev range. This is done by putting
the throttle stick to mid position, then setting the trim back all
the way and then pulling the throttle stick back to idle position.
An engine shut-off from medium rotation speeds achieves a
gentler cool down of the rear ball bearings and the whole
system
.
Put the model against the wind and wait until the after cooling
process is over (around 2 minutes).
When completed,
you can
turn off the receiver unit.
Check
the model’s fuel supply connections and de-fuel, if
necessary.
