I had the first problem with mine, I didn’t allow the gps to connect and switched it to manual to launch and when you switch to stabilized or rth it just cuts the power, as for the fly away I’m not sure I have never had that with mine.Last week i installed the ZOHD KOPILOT in my ranger 1600 .
I'm not very familiar with flight controllers and my main reason for getting one was so i can fly fpv and if i should lose signal it should RTL.
this feature worked great when testing it out last week and the auto launch feature was super cool.
Today i took it out to a new location for an fpv flight (Big dry mudflats in front of me and tall grass over 1.5 meters tall and thick bush land behind me with houses behind that).
I switched to manual mode and launched but when i tested RTL the motor died and was not being able to get the motor to re-arm i tried switching through to different flight modes so had to glide it back down.
This happend on the first 2 launches.
This should have been enough for me to realize something is not right and mabey pull the pin go home and investigate.
But i was so keen to have a fly i plugged the battery back in waited for it to re-arm and went for round 3.
BIG MISTAKE!!
This time when testing RTL the motor didn't disarm but throttled up and i could tell from my fpv feed it wasn't heading back.
I ripped off my googles and desperately tried to find it in the sky.
I could faintley hear it flying away but had no visual and could tell it was a long way away.
Then it went silent ( Either too far away or the motor dis-armed )
I walked for about an hour and a half with my googles with me in the hope i might pick up a video signal and my radio constantly tellling me rssi low,/critical telemetry lost, telemetry found .
I felt sick in the guts as I'm sure the bushland is riddled with snakes and with the tall grass it could be anywhere (Tree, Burried in the tall grass in someones yard or roof) and just as i was about to call it quits and head back i found it.
As luck would have it it landed in the shorter grass (Long way from RTL) in front of the heavy scub and trees
So very lucky.
The warnings were there and i was silly enough to ignore them. ( I've learned my lesson).
So now to my question .
Any idea what might have happened ?
I'm thinking when i hit RTL the ESC's BEC might be having trouble providing enough power for the 4 servos ,receiver and the flight controller .
maybe it's shutting down the ESC temp. and then trying to reboot the flight controller.
Not sure.
