Hexacopter Looses Calibration

Posted by Daniel Estes on May 25, 2013 at 11:24am

After 30 to 45 seconds I begin to loose control of the copter.  I am not sure if some of the updates changed some of my settings, or I screwed something up.  

I placed a brushless gimbal to the copter and I don't know if something from that is messing (frequency/vibrations) with flight controller.  NOTE:  I do not notice any vibrations.  I am going to test the copter again without the gimbal in operation.  Also, the gimbal has it's own controller and is powered by a seperate battery.

Ardupilot Mega 2.5+

I calibrated - Leveled the copter and tried to do the Auto Trim.  I didn't notice any difference.

Please advise.

Thanks.

    If it flys fine without the gimbal and does not fly well with it. Then the gimbal is your problem. How close is the gimbal setup to the APM? Can you provide a picture?

    You're not powering the servos from the analog output pins are you? That can deaw too much power and brown-out the APM

    I tested the copter without powering the gimbal.  Everything seemed to work well.  

    Question:  Can some of the brushless gimbals cause a problem with the flight controller?

    I am using the Master G brushless gimbal with its own control board and IMU.  I am also powering the gimbal through a seperate lipo battery.

    Can the frequency of the motors and/or wire placement mess with the flight controller?

    Thanks.
