IMU Problem after a bad crash

Posted by Philip Fretwell on June 5, 2011 at 12:21pm

Hi All

 

Took a bad tumble with my home brew Hexa yesterday.  I was flying 2.023 and I let the Hexa have its head when testing RTL - big mistake.  5 props and a couple of broken bolts.

 

All now fixed and upgraded from M3 to M4 bolts much beefier....

 

My problem is that when I boot up I get the red and green leds flasing alternatly very fast and the gps won't lock.

 

I have reloaded the firmware (love the new interface) and runs setup etc and all tests seem OK.

 

I'm now a bit stumped and would welcome some advice....

 

Philip

    Run your the tests in the CLI and see if one of the sensors was damaged. Pay particular attention to the IMU and compass tests.

    Hi,
    What GPS are you using? The ublox module has a very delicate connector and, if your adapter board wasn't secured to the module well enough, the connector between the ublox module and adapter board may be damaged from the crash. If you are using ublox, please inspect and report back.
