I’ve been flying with pretty much this same hardware setup for the last 18 months or so and have moved the build across a couple different frame types. I currently have setup and tested flight modes Stabilize, Alt Hold, PosHold and RTL everything so far has been pretty uneventful.
I have had only a Few bumps along the way, a bit of a learning curve moving from Dji N3 FC’s. I am still struggling with deciphering logs and getting my tune dilled in etc… till now.
I recently upgraded to larger batteries from 6000mAh to 9000mAh and started testing what my new flight times would be yielding when I started to experience the following scenario.
I take off in PosHold and hover at 1-2 meter height and after 1 to 2 minutes the copter just falls straight down to the ground. The last four flights have produced the same identical outcome each time. During that time I have used two different types of esc’s, inspected and rewired my power distribution system and installed a new PBD, re-flashed ESC’s with latest version of Blheli32, tested and calibrated and continue having the same failure.
In the link posted are all related logs, prams, configuration info, video clips and photos.
The two video clips are about one minute long and on both the crash happens in the last 10 seconds.
I’m stuck, depressed, demoralized. I hope someone can help me please.
