I am using A3 flight controller on an octocopter(Kraken V3 130) with Lightbridge 2, I have done more than 25 flights till now with the setup. Recently I upgraded the firmware to version 1.7.1.5 from 1.7.0.0. After the upgrade on the very first flight, I encountered a signal loss after few minutes of takeoff and the platform was only 5 to 6 meters away from the homepoint. After which, the copter started gaining altitude on its own and several attempts were made to regain the control but there was no luck.

Here is the log file and the video can be found on the link below

  

Did anyone encounter the similar problems.?
Please share your thoughts on what might have created the problem.






Thanks in Advance.)
