I had a strange crash recently caused by total failure of rx power and can't decide if it was due to the regulator or the battery or user error on my part (ie not chargeing it enough or hitting manual discharge by mistake) .

I'd had about 4 flights on my knight 50 3D and noticed that it had got down to the last green light on the Align regulator.To have another flight i put about 800mA back into it with my Simprop Intelli control charger set to about 1.6A charge rate on Lipo setting.

After putting some charge back in (about 800mA) i switched on the reg and it was showing the top green when all the sticks were waggled.But i didn't check it with my duralite checker with a 1 or 1.5A load.

I flew the heli and about 3 minutes into the flight it fell out of a low backwards roll on knife edge.I had to rush over to the heli and pull the fuel line off before the clutch burnt out:-)

On arriving i left everything as it was with tx still on .I noticed that nothing worked at all,no display on the GY601 amp,no lights at all on the Align regulator and no orange lights on the Spektrum rx's.
I tried the on/off switch on the regulator several times but it made no difference.I checked the battery with the Duralite checker and it rapidly went down to about 4V even when not loaded (but still connected to the regulator)
so i was convinced it was the battery at this point and a cell had suddenly died or something.

I disconnected the battery which has a deans connector on it and checked it later when i got home with a multimeter.It was back up at
over 7.4 volts.I then took the shrink wrap off to check the tags and soldering and found nothing wrong and partly charged it up to see if would take a charge ok.

At this point i thought it was now the regulator that had failed perhaps draining the battery rapidly in the process.
But i didn't check the reg out until about a week or two later while i was repairing the heli.The regulator is now working normally with the same battery connected.

Has anyone ever had a failure like this or do you think i just didn't charge the battery enough before haveing another "last" flight?

The heli is Knight50 3D
Gy601 gyro with 9251 servo
3 x 9252 on cyclics
DS811 throttle servo in DS mode on Revlock20
