Help, my arducopter is possesed!

Started this discussion. Last reply by David Posea Feb 1, 2013. 16 Replies

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,…Continue

Transmitter too sensitive

are there parameters to tune to make the transmitter controls less sensative? Like parameter based dual rates? I have searched but can't find any solution except setting expo pretty…Continue

I have to share my first flight with you guys. I spent a lot of time checking and rechecking everything in my new hexacopter, and yesterday was the first flight attempt. Our flying field has covered…Continue

"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."

"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…"

"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…"

"It was the board. Roll, Pitch, and yaw all stay nice and steady now, as well as altitude."

"I tried everything, and got nowhere. My new board should arrive today so I can compare resutls. It's just really weird yaw would change so much, so fast, with the hexa sitting on my pool table."

"Just curious, did you try the reset button on the board? You might want to try the erase eeprom command again and try a re-calibration."

"the reset and reprogram didn't work. I have a new board on order. It has to be hardware. Altitude is also pretty unsteady with the hexa sitting still."

David Posea replied to David Posea's discussion Help, my arducopter is possesed!
"I'll give it a try. Roll and pitch are working correctly now but yaw when graphed looks like a heart monitor! I don't think the hardware is really at fault. It looks like the PID loop eliminates error a little at a time, until it gets…"

"You might want to give this a shot. Use the CLI to reset and erase the eeprom and reload the firmware. http://code.google.com/p/arducopter/wiki/AC2_CLI I had the same problem of my new quad APM2.5 crashing causing the gyros and magnetometer go out…"

"I do firmware development so I'm sure I can figure out the GUI. I ran the terminal setup / level command and it says gyro did not converge, diff=1.123 (various values). It seems a hard knock must have damaged the gyros. I check the board under…"

"I forgot to mention I've been flying an MK for a year or two, it wasn't pilot error. Based on new data from MAVLink I think I have hardware issues. I started another post for those."

"Remember there are only two types of pilots, those that have crashed and those that have yet to crash. LOL I recommend you test flight in a large open field, until you get fair amount if flight experience. Good Luck, Richard"
