So you are using a 3s Li-Po, this is the worst battery as the electronics have to reduce the voltages through out and everything runs hotter in the electronics. A 2s Li-Po with a good C is the best option. Li-Fe packs are supplied with shipping regulations in mind.
So, if you press the spool button the turbine does not turn?
If you do a learn RC again does the ECU see the throttle pulse change on the display?
Is the temperature reading around the correct ambient?
Lastly which country are you in.
