I have a new Arducopter running 2.9.1 that flew a few times after being put together. It started bucking wildly in flight and now won't take off, it just flips over.
Has anyone ever seen this? I have checked my connections, calibrated the ESC's a number of times, set the compass, but it still wants to take off and flip over backwards...if I give it a little throttle the front end picks up long before the back.
I can compensate with controls but it never used to do this.
Anyone have any ideas?
APM is facing forward, checked prop rotation numerous times, set for X type. What do you mean by "level"...in the mission planner? I have done that numerous times as well. I have read of another way to level the copter with the battery plugged in...hold left yaw for ~20 seconds...is that right?
I don't remember the artificial horizon doing weird things but I will certainly have a look to see if that is happening. I have checked all of the wires..to the point of disconnecting everything and attaching it all again.
I can fly the helicopter but with serious stick manipulation, it just won't take off any more.
Is there a hard reset back to factory that I can do and then try updating all of my software again?
is there any repair I can do to the gyro if this is the case? I am having this same problem and on the MP the artificial horizon is doing weird things!
Once you have gyro damage there is not a lot you can do except order a new board.
Had it happen a couple of times after crashing.
Mark, and all, I have had the same problem but miracously when I reverted back to 2.8.1.. no more problem with strange things happening to the artificial horizon in the MP.
Honestly, I don't trust 2.9.1 fully for reasons I cannot fully explain, part gut feeling. 2.8.1. was very stable and with 2.9.1 I got crashes, lock up of APM with total lack of control (hence crash), strange things happening to artificial horizon. It broke the Optical Flow sensor I had as well.
I even went sofar as to buy a new APM 2.5 (already had APM 2.5) because I thought the gyro was broken.
Guess what, the new APM showed the same artificial horizon issues. Even when doing all the calibrations, checking X or +, resetting/erasing etc. etc.
I have gone back to 2.8.1. and she flies a beauty at the moment. Waiting to 3.x I guess before I will update again.
Stefan: When you're using 2.9.x you need to do the new accel calibration. Were you doing that? It won't fly properly until you do.
Thanks Stefan! I actually was able to solve it by doing a hard software reset.. I uninstalled MP completely from my computer and uninstalled the APM from the device manager. then reinstalled all of it and uploaded a fresh 2.9.1. I did have to uncheck the external magnometer box as it was checked when I uploaded it. after that it was working pretty great! although I think I noticed some compass drift during flight yesterday but more to come on that!
So after testing and re-testing the propeller directions, calibrating the ESC's, leveling, etc. I finally went the route of a hard reset and re-installed the system. I then went about manually testing and calibrating everything via the CLI.
Long story short...the copter is in the air again and working like a champ. I also came across a helpful tip to always disarm and level from the remote when I am done flying.
Thank you for all of the help from the awesome community here.
Up next, upgrading to a hex as we can't life enough video/camera gear with a quad.
