I had a minor crash today and I would greatly apreciate any help help I can get from you guys:)!
I have been flying this setup without problems with about 60 minutes of total air time experience. I have been flying in stabilise, alt hold and loiter without any problems. Loiter and alt hold are very stabile.
Today I took off in stabilise, then switched to alt hold and then loiter. Everything was going fine. I flew around in loiter mode, where the sticks simply control direction while maintaining altitude. When I was about to land I was still in loiter and brought the quadcopter down to about 4 meters, still in loiter. Then I thought I switched to alt hold but from the log I can see that I switched to stabilise which should also be fine. However the moment I switched to stabilise the all motors stopped and the copter dropped from the sky. My throttle was a bit above middle which should be fine to hover. My copter hovers fine at around 50% throttle. From the logs I can see that throttle out is reduced to almost zero when it enters stabilise mode. Throttle in is about 50% you can see that I raise throttle as the copter drops. When it hit the ground I lowered throttle to zero.
Any help is greatly appreciated:)! Below you can see graph of throttle in, throttle out, voltage and current. I do not have any low voltage alarms or cut-off enabled. Logs are also attached. I removed the beginning of the flight in the .log file since it was larger than the 7mb limit.
I'm using Arducopter 3.0.1 release.
