Pat if your turbine is set to idle at loss of RX signal, then it makes sense that the IO lights would be flashing with the ecu powered up doesn't it? Otherwise the turbine would automatically stut down with RX power failure.

Hi Duncan
It is set up to go to idle if the Rx goes into failsafe, and this is checked by switching off the transmitter. Not sure what happens if the Rx is switched off though - hence my question. From memory, the ECU has always been off with the Rx off, and when you switch on the Rx you get the beeps as the ECU initialises. The sequencing lights stay off until you advance the trim out of cutoff, then start flashing in order until you open the throttle, and then they indicate in accordance with the start sequence. Just seems odd that the ECU had any power with the Rx off, and very bizarre that all three LED's were on at once.
The newer V6 ECU's have the power on with Rx off facility so you can power off the radio gear while the turbine is still going through the cool down sequence, but this early version has no such clever stuff. I have a V5 ECU that I'll use to test the turbine with. This one ran on NiCds, so I'll need to get it sorted for LiPo power first.
Cheers - Pat
