Flew 3 flights today, having the best time, plane flying great (crap, I almost looked like a pattern flier!). Went to power up for 4th flight and heard the ESC counting cells, so I knew auto voltage limiter was turned on. This was not my setting so I called it a day and took it home.

Just hooked up to computer: all settings returned to default. What happened? Should I continue using or send in for service? I think this might have happened once before when I first started out electric.

I checked the service advisories and my unit checked O.K.

I had the same problem with an HV85. I reset the settings back to my parameters and flew it. It died on arming after a few flights. My other HV85 died on arming as well. Castle replaced them but I don't know what happened. I flew the new one today. All was well.

I hope you find out what happened
