There will certainly be an -rc6 to resolve some known issues including:
Any reason to expect different compass behavior with this release? MP reported “compass not calibrated” after updating from Rc4 (chibios both). And the 2nd on-board compass on the PixRacer is not recognized when doing the calibration. I think this can be seen in the device ID’s comparing them to the Rc3 release which is the last I have a saved parameter file from. They are identified differently.
Hi I like to install using load custom firmware can you give me the direct link to the directory for px4-v3 rc-5? I am lost. normally it in the latest directory? but the firmware does not say RC-5 after loading unless I use MP load beta. Where is MP pointing to?
That is a bit of a concern. There was a change related to the compasses. It was meant to be a non-functional change but perhaps something went wrong. Txs for the report. I think we should be able to reproduce with a pixracer but we may need a dataflash log file from you…
Brandon,
Txs for the report. re EKF errors during dataflash log downloads, I think that happens in Copter-3.5 as well. It’s potentially something we should fix but we may not fix it in Copter-3.6.

When I started the takeoff all seemed stable, but at about 3 feet the quad took a nose dive and landed on its back. Ended up with only one broken antenna.
Actually I have a hunch that the cause is due to mechanical failure but I’m not sure. I am not proficient enough in reading the logs so any input would be appreciated.
