Can't fly after 3.0.1 upgrade... tries to flip itself..

Posted by Jason R on July 22, 2013 at 4:52am

Hi - I have a APM 2.5 on a DJI 450.  It was flying great on firmware 2.5.   I just upgraded to 3.0.1, re-calibrated the radio, accelerometers, changed the PIDs as instructed -

I can't even take off anymore.  It flips over as soon as it gets any throttle.  Both in regular armed mode and autotune mode.  The motors also seem to be more aggressive at low throttle.

Any ideas?

    Ok, fixed it.  Dumb mistake.  When picking which BIOS to install, I thought that the first quad was the "+" version and the third was the "X" configuration.  The third is actually for a 4-arm octarotor.  I forgot the choice for + vs X was later in the install.

    Works well now.
