Pat/Gary,

Can't help you with your issue but I had a very strange occurence a few weeks ago.

After the last flight of the day on my Hunter, powered by a P160SX, I turned the radio off and let the turbine continue the cooldown process. The all completed absolutely normally and I packed up for the day. Now I normally unplug the ECU battery as the ECU will continue to drain the battery a tiny amount but on this occasion I forgot about the battery and instead I left it plugged in. I realised whilst driving home but wasn't too concerned as the turbine won't run without the radio on.

However later that evening I was playing with my TX and I kid you not I heard the starter motor enagage on the turbine for a second of so. To re-iterate the RX was NOT on when it did this! I was completely amazed at this behaviour as it was the first time I have ever seen this. The turbine didn't start thank god, only the started motor engaged as explained.

As a result I am telling everyone that is it vitally important to completely power down the ECU by unplugging the battery. I have no idea whay it behaved likeit did but I believe its related to the relatively new facility where you can turn the radio off and the cooldown continues. Previously, without the radio on, the ecu would stop working immediately.

And before anyone else asks the ecu works fine as I have flown the model 4-5 times since.

Geoff.
