Hi, can you help me understand why my arducopter just fell from the sky when I was landing it? So I was trying the new fpv system I put on my drone, all was fine for like 14 minutes, then I saw the battery getting pretty low, and returned it manually (in loiter mode), I started landing it, but then like 5 meters above ground it started falling really fast, I switched back to stabilize and went max throttle but the motors didn’t start spinning faster! Note: it wasn’t disarmed! Luckily the crash has been avoided, and it just hit the landing gear hard. After it fell, I touched the fpv and it was hot as was the LiPo. The vtx was touching the apm board and maybe it happened because of overheating the board itself, not sure about that. And I also want to point out that it was the second time flying with fpv, in the first flight happened the same thing but it already almost landed. Also the voltage on the lipo was not lower 3.4V / cell, I had a voltage alarm. I attach the log file, maybe you can find something in it. In the log there are 3 flights, so you will see 2 or 3 landings. I think you can figure out which one is the one where it fell by altutude change. Also after the crash I tried to take off in loiter and it worked just fine!
