  I am buildng a Tarot 650 Sport quad, using an APM 2.6 F.C. It has been a challenge finding a version of Mission Planner to connect, load the firmware and successfully calibrate the accelerometer. I got to the point where I can connect to my Windows 10 desltop running Mission Planner 1.3.75 but when I try to calibrate the compass I don't get the little dots that I'm supposed to capture as I rotate the aircraft. I have tried everything I can think of with no success. Here is a video that shows what I've tried:

  If anyone has any suggestions, please let me know! Thanks in advance.

  Hello,
  
  I have a quadcopter with:
  
  2 Lipo 6s ()
  4 ESC Monster 2000 ()
  4 motors rotomax 80cc ()
  4 propellers
  
  But when i arm ans start motors, one motor stop spin when i pull thé throttle to max.
  The total weigt of the quad copter is 60kg. The drone dors noté take off even i pull throttle, Elevetor toi max.
  
  What Can tout advice me :
  Change ESC to 14S?
  Change the 2 Lipo 6s with a 14s battery?
  Change propellers with bigger propellers ?
  What else?
  
  Best regards

  I have just build a quadcopter with an F450 frame, a Pixhawk 2.4.8 and MP. When trying to take off, the quadcopter tilts - the front is lifting much more than the back (and I have not gone any further...). I think I have done all the MP setup steps and calibrations (Accel, compass, radio, ESC) - any suggestions, please?

  I recently switched laptops and now have Windows 10. I installed Mission Planner on my laptop and plugged a mRo SiK Telemetry Radio into the USB port. The radio is not recognized on the com ports but is instead on the "Other Devices" tab in Device Manager as "FT230X Basic UART", the FTDI chip in the radio. When I go to properties it says no driver is installed.
  
  I've tried multiple mRo radios and an old 3DR radio, different USB ports, updating Mission Planner, uninstalling Mission Planner and reinstalling, installing QGroundcontrol, and uninstalling the radio in device manager and plugging it back in.
  
  I've spent some time digging through forums trying to find a way to manually install drivers or to find out if Windows firewall is somehow blocking it with no luck.
  
  Any advice would be appreciated.

    I had this issue with the Ground unit of a 3DR 915 MHz Telemetry Radio pair. I am running MP on Windows 10, and Telemetry RSSI was always zero, even though the LEDs seemed to indicate a radio connection was made. I had to study the chips on the ground unit PC board. In my case it was a Silicon Labs Si1000 in the radio half, and Silicon Labs CP2102 USB to UART Bridge on the USB half.
    
    I tried finding the driver on Windows Update but what they had didn't work. I then found my way to the Silicon Labs web page and downloaded the Windows VCP driver, installed it and voila!
    
    I was finally able to "connect" to MP from my UAV over the Telemetry Radio!
    
    Perhaps you can identify the FT239X Basic UART chip (on the PC board) and find out if the manufacturer provides a driver.
    
    You also mention Windows Firewall was blocking something. Is it the download of the driver? Or the driver itself?

  I made a drone with /MissionPlanner 1.3.61, navio2 + RP3B+, ardupilot

  I get this message when I do a motor test.

  "Command was denied by autopilot"

  How do I handle this?

    I'm still very new, but I've been working through the same issue. There are pre-requisites for Arming, in the Flight Controller's firmware. I'd suggest going to Full Parameter Tree in MP and looking at the ARM group of parameters. That may give you some idea of which preflight conditions are expected and which are not being satisfied.
    
    There is also a Status tab on the lower left side of the Data Screen. It's scrollable right to left, most parameters in alphabetic order, showing their current value.
    
    I hope this helps.

  Hi to all!

  I am from Brazil and I am finishing my thesis to get my Doctor's Degree.

  I have an energy model for quadcopters and I need some data to do a final check in the model.

  I have spent the last two weeks tryng to find those files in the Internet.

  I need the binary log or DF log of the Ardupilot such that I can convert it into a .mat file. Then I can use my Matlab program to read the .mat file and d the rest.

  Please, if you have files like that you can make it available to me, please  post here or send to my email : joao.marins@inf.ufpel.edu.br

  As additional info, I need to know:

  - the model of the quadcopter;

  -the weight of the quadcopter;

  - the propellers used for the flight;

  - where the flight took place.

  I photo of the quadcopter would be an extra so that I can put that  in my thesis.

  I will be very grateful if you can help me.

  Best Regards!!
