You were absolutely right - the turbine´s running again
Many thanks for your "obvious" advice we did not paid too much attention at first and which turned out to be the right clue to our problem. So here´s what happened :
When we re-connected all the cables back to ECU after finished repair of the fuselage and wing we did not notice one "small" difference we made in the ECU´s sockets labeled as "Thermocouple/RPM sensor/AUX Rx input/Throttle input" - while we were making sure to have the black cube connector correctly oriented with the white dot toward the LED light we completely overlooked we connected it into the RPM sensor&AUX Rx input sockets instead of the Thermocouple&RPM sensor sockets ! I enclose the pictures of wrong and right connection to illustrate our mistake that can be done by any beginner like us :
WRONG CONNECTION RIGHT CONNECTION
When we re-connected correctly the engine started and ran without any problem.
Now we are able to go to fly soon again hoping we eliminated flame out repeating by replacing all the tygon tubes for the PU ones because of the FESTO coneections and by making loops to avoid any sharp turns.
We will keep posted on our further experiences and we wish to thank to
for their valuable information so far
