Hi, I had a strange flight today, I tried the logs but was not able to diagnose...
I did a first successful flight and run auto tune no problems at all, then I attached a gimbal, and moved the battery to a new position to re-balance, the flight started without any problem, then at 1minute and 50 seconds I had a kind of power loss, but the propellers continued to run, the copter even bounced on the ground I tried again but it happens again right after the take off.
When I tried to connect it to the computer I got the io b/e led blinking with the act blinking too, after several connects and disconnects it finally connect and I was able to retrieve the logs, they are attached.
This IO error is stated at documentation that only developers should get, and the strange is it is intermittent, sometimes happens some times not...
Now at home, it happen again, the copter is saying I do not have compass calibration, I tried several compass connections re-connections do not know if I have a bad external compass or some other problem.
I have uploaded the video from the gimbal at http://youtu.be/kgC3aMTV5Fw
If ay of the developers could do a look o my logs I will really appreciate. Thanks

Hi Leonardo,
I have looked at your log and while I don't know anything about the error code you are seeing I can tell you why your copter came down.
You are loosing something in the power system on Motor 3. Motor 3 is struggling the whole flight and near the end it can't provide enough thrust to keep the copter level and maintain altitude. So all the other motors must drop thrust so they don't flip the copter. The result is the copter comes down.
Have a look at your motor outputs in the 14-00-30 log. You can clearly see it.
I don't think this is related to the other issues you are seeing though.
