Priming
It is strongly recommended that after a new installation or modification to the fuel system that the
system be primed to clear any debris collected in the fuel line before connecting to the engine:
(Note the
engine
itself
does not
require any priming)
To prime the fuel system, disconnect the fuel pipe at the engine and route it into a suitable con-
tainer. Set the throttle and trim to low and proceed to the Pump Prime option in the INFO menu.
Run the fuel pump for a few seconds and be ready to hit the off button.
Note the ECU battery must be connected to do this. This will help clear
any air and particles that could have entered the fuel system during in-
stallation.
Don´t do the prime directly into the engine as it could sweep any bits
from the fuel system straight into the engine, always prime into a jar or
outboard for a few seconds.
ECU Display
There are two display options with the “X” Series engine, depending
on which package you select. One (top right) is a very small black
and white small screen integrated onto the Hub and housed in a
plastic box, called the Compact. This is internally electrically con-
nected to the connector board so requires no additional lead, but
cannot be removed from the plane.
The other (shown below right) is a separate multicolour high resolu-
tion display mounted in a small case with a servo type lead coming
out. This can be plugged into the Hub as required or can be con-
nected and mounted permanently in the plane.
Both displays include dedicated screens for engine operation, radio checking, last shutdown cause
and other special turbine operations.
ECU data record / playback
(Note, this function requires the Hub Lite colour display to be mounted permanently in the model)
A most innovative and useful function is the internal recorder/playback function. The multicolour
high resolution display continuously stores all the data received from the ECU, keeping in its per-
manent memory all the data of last 66 minutes of engine run.
After the flight the display can be removed from the plane and be powered up with a receiver type
battery and the data stored can be played back in real time, same presentation as if the engine
was running. Playback mode can be still, forward or reverse, speed x1, x 10 and x100 in both di-
rections, so that would be easy to view the engine operation or investigate any issue at the field
without the need of a computer or any other type of reader.
