Hi, I had a bad crash with my Hquad, was running V3.1 firmware at the time.
Apm 2.6+ gps/compass combo.
Hk h4 frame
ipower 2814 750kv motors
Hk blue series 20a esc's
5000mah zippy 4s lipo
AUW was about 2200g with brushles gimbal and i had an average flight time of 16 mins
I flew one battery pack fine, no problems,
Second pack i was half way through, had about half the battery power left.
I came down to maybe 15-20 feet, everything was fine, then suddenly the copter started wobbling, violently, and literally fell out of the sky.
I parked up what i could find and didnt touch them for months(lost my gps module, lost two motors, lost my fpv gear.)
I put in tons of time and effort, modifying my frame, making custom vibration mounts, adding a brushless gimbal researching motor+prop+power combinations etc etc, was pretty proud of myself. I was pretty bummed.
Then that crash happened....more or less totaled the frame, was kinda down about it for a while. Now im ready to rebuild, but I have no idea what happened that day, why it just fell.
M battery wasn't dead, I had an osd with a voltage reader, double checked everything.
I have also since then, tested all of my escs, they work fine.
The flight logs don;t have IMU data, disabled that as i read somewhere that its cpu intensive.
I am unable to understand much from the flight data besides checking the map, and seeing if my vibrations are within tolerance levels. Can someone here help me understand what happened? maybe? I have attached the last two logs, one right before the crash, and i believe the second is during the crash itself.
Thanks in advance
