After a minor crash I've fixed my hexa copter but in MAVLink under flight data, in the status tab, roll, pitch, and especially yaw are changing wildly. The horizon in the flight hud jumps all over, including upside down!. I have downloaded new firmware, recalibrated the transmitter, calibrated the compass, leveled the hexacopter and it still does the same thing. Also, it doesn't really seem to respond to movement either, or the values change so rapidly that I can not see the changes for movement. My APM 2.5 is wired correctly according to the recent post on connections. I'm not sure where to go from here. Is my APM trashed? Oh, i've tried monitoring with both 3DR radio and USB connections, too.
HI David, I rushed to conclusions. I think I have the exact same problem as you. I thought the erase eeprom command work but apparently the sensors will work for the 1st minute before going sluggish. I suspect this was what caused my 1st crash. My replacement board is free from these issues.
I updated the board to the latest firmware 2.9 and all seems well for the 1st minute and then the sensors just went sluggish and non responsive. I'm sending it back for my dealer to take a close look and possibly ship back to 3DR for analysis to see if this is a QC problem.
Im having the same sort of issue, but this APM 2.5 is yet to actually fly, its brand new fitted to the air frame. Calibrated everything, yet the hud jumps all over the place sat on the desk.
When i first installed the firmware it was sat on the desk and the hud was fine. That was 2.8.1 I think, now it has 2.9 on it.
Guessing its not a good idea to fly it like this.
All I got was a hard flip on takeoff. I got a new board and my arducopter flies very nicely now. I didn't send the board in because I crashed the heli, but now I might it it's a common issue.
