I managed to flash some turnigy plush ESC's for my APM quadcopter and at firts glance it flie great. You can really see and feel the difference compared to the stock FW of the ESC's.At a certain moment the quad just flew to the side and crashed but luckely nothing damaged. It was like one motor just stopped.Doing some hand tests I saw that one of the motors reduced sometimes in speed. But then regained again. I think that the ESC is going bad.Now I would like to know how to analyse this in the logs. You can probably see that the output to the motor is still good but still it reduces speed. Where can I see this?I want to make sure its the esc and not the APM 2.0 thats going bad.Thanks

Enable 'motors' in the logs (http://code.google.com/p/arducopter/wiki/AC2_datalog), then you can see the output to each motor. Feel the temperature of each ESC when the problem occurs. Also check if the problem occurs when there are only a few sats found by the GPS or when in the flight.
