This my 3rd crash with similar way, dipping.... out of no reason. I am currently flying Y6 AC2 2.0.48. with GPS and Magneto.
My previous 2 crashes was with earlier code. My 2nd crashes happened even after i solder the connection between esc and motor. After the second crash I change most of the esc signal connectors. After that it seems ok till the 4th flight. That is when I crash the third time. I even mount the quad for test previously but nothing happens.
BTW I hv been using Arducopter for a year.
Attached is my flight logs. Hope someone can help me to identify the problem. If possible provide some guide on what to look for so that i can troubleshoot myself in future.
Thanks a million
i wonder will it be better to just use the + - terminal on APM. I use that when I first started. Wonder why they don't recommend that.
I actually is having problem getting to engage the GPS lock (red led) with power from BEC. I use USB to power up and the GPS lock possible.
Seems problem is endless. Not blaming anyone.
Update: no GPS lock due to redundant power from ESC. Now back to single power source from separate BEC, with all ESC -ve terminal shorted and connect to APM -ve at output channel.
Going for test, wish me luck.
Update: As per today, no crash. I am glad. The only change i made was to short all negative terminal from ESC and connect it to the APM output channel negative terminal.
Glad to hear it worked for you too, it is a strange ting, since it can be measured that the Ground is hard-wired inside escs.
