Little Flip

Posted by Pascal06 on September 1, 2013 at 2:08am

Hello,

One month ago, my arducopter crash because of a little flip (not sure if it is the correct term) at low altitude.

After a motor mount replacement, I decide to try again and make a video to show the behavior and attach the telemetry log file.

How can I fix this behavior ?

Thanks in advance,

Pascal

    I'd also check the electronics such as solder joints at bullet connectors etc. I had a similar issue with 3 pin inline connectors s between Speedy & Motors. Some of the factory solder joints were like bird poop too. When soldering Motor wires the wire strands generally need scraping or cleaning as they are lacquer coated. If not cleaned you will only solder to the very tip of the wires.

    I also suspect that a motor is stalling while flying.  I'd also say have you done the ESC calibration?  You can also try raising the THR_MIN from 130 to 150 to see if that fixes the problem..but that shouldn't be necessary if you've done the ESC calibration.
