Sorry for posting here, but this great threads seems to be accumulating some knowledgeable miniature turbine folk. :-)

My P20-SX has been out-of-action for a couple of weeks, as by accident I plugged a 4S (14.4V) battery into the ECU instead of the correct 2S (7.4V) battery. The ECU went bang (there was smoke!) and that was that. :-(One of the consequences after I blew-up the ECU, was that if you tried to power it up again, the starter motor would just spin without being instructed to by the transmitter.

I sent the ECU back to JetCat and they repaired/replaced it reporting that the PSU element had been fried. With the new/repaired ECU they returned however, although my P20-SX now trys to start normally, it fails with a “LOW RPM”. Please see the video below, it seems like either the RPM sensor is faulty, or the logic in the ECU which reads the RPM is faulty?<o></o>

Does anyone have any suggestions what I should check?
