"Hi Randy, Thanks for that, something I did not even think about. I could now say that I am not that low on the throttle to make it stop spinning, but I think you might be right. I will give it a try. I will also turn on the Motor loging and see if…"

"Andreas,       Because it only happens when the throttle is low (i.e. landing), I'd guess that that motor's ESC needs to be recalibrated.  When you calibrate it you ensure that the ESC knows what the min…"

"Hi Randy, Please help me out. I have posted this http://www.diydrones.com/forum/topics/please-help-reading-logs?xg_source=activity   a while ago when I had a crash because of Motor nr. 4 stopped momentarily close to the ground.  I…"

"Hi Randy, Please help me out. I have posted this a while ago when I had a crash because of Motor nr. 4 stopped momentarily close to the ground.  I took my Copter apart, redid everything and found a rubbing wire on motor nr. 4. All confident I…"

"Brian, When last did you clear the logs. I have has this behavior when the log files filled the ram. It will fly just fine in stab mode, but auto and RTL modes confuse the APM. Worth a try. Regards Andreas"

"Hi David, The trick is to make sure the gimbal stays level with the table that the copter is placed on. Just making it move is not enough. A good way to check is holding your copter up and look in the mirror while it's recording. As you move it…"

"Hi David, I did it the same way and these are the results. The AV 130 works allot better than most say. You have to spend time setting it up though. https://vimeo.com/67626748 Regards Andreas"

"Hi Jimmy, This is what I have. Please note, my one is flying on an APM 1 with firmware version 2.50 Kind regards Andreas "

"Don, check the link, they have to rotate a specific way for this to work.http://code.google.com/p/arducopter/wiki/AC2_Props_2"

"Hi Don, Firstly, look at the direction of your motors, some of them seam to be spinning the wrong way round. Secondly, you need to re-level the copter in Mission Planner. That should get you going. "

"I personally redo all solder joints even on the ESC's. But then no one is perfect. I will have a look and report back what i found.  Thanks for the help."

"The problem is most likely an electrical connection if the aircraft has been previously successful. If, as you suggest, a section of motors failed, the power distribution would be where I checked first. A week or so ago, one member found broken…"

"Hi Doug, It's the correct file. Thank you. The copter has done very many successful flights previously. I have not changed anything, that is why I am assuming that it is a hardware failure. I see what you mean with not having enough data. i…"

"OK, the firmware loaded is for a Hex frame -- is this your configuration? -=Doug"

"Hi Doug, Thank you that is what I was looking for. I do know how to read the t log files, but as luck would have it, i was not connected at the time. I will see what I can find. Regards Andreas"

"Hello and sorry to hear of your crash. HERE is the page that discusses reading logs. There is a video down the page a bit that is excellent - watch it. I will take a quick look. Many times more features need to be enabled to catch all the data…"
