After flying my 3rd lipo in a row with no real problems, suddenly the copter takes of very agressive. Was flying in alt hold when it happened. No reactie from the remote when trying to bring the copter back to launch position. Switched to STAB and landed. After this all looked normal again. Except the broken landing gear...
Logfile and sketch attached. Anyone had the same problem already and knows how to fix it?
I had a look at the log file. It seems the copter rolled heavily to the left after rolling right. Maybe it was a little unstable or windy or your gains aren't tight enough.
The copter increased thrust to maintain altitude which caused it to shoot off in that direction rather fast.
It appears you had control until it hit the ground right before you entered stabilize mode. The ATT messages show it responding in kind to your commands.
Why the left roll happened I'm not sure entirely. Were you in Simple mode or normal flight mode?
I'll keep looking into it.
Simple mode is enabled per switch position. This enables users such as FPV flyers to do more complicated setups. You may have been confused since the Quad was rotated at 45 degrees and when it wobbled off your controls were not translated by simple anymore. if you do run into trouble, it's best to flip right away to Stabilize.
There are two ways to handle Simple mode. You can set CH7 input to toggle it independent of mode. Or you can set them permanently to each switch position and use CH7 for another function such as saving waypoints.
There should be little checkboxes next to the drop downs for each mode switch position that turn Simple on or off for that mode.
Note: The CH7 option overrides the checkboxes.
