And the fallback settings on your arm channel is set to HOLD?


And you have set correct throttle values?

How quickly does your quad disarm and drop? Immediately after you go into faisafe? It sounds like you are not even reaching sanity checks for Stage 2. If you are on BF4.5, the drone should hold for 20s even if it fails sanity check. Again if you have blackbox logging, check it may tell you the flight mode it was in before it disarmed.
Mstc you have pointed something interesting,I will check later ,when I have access to quad the aux 1 arm channel if it is set to hold because the quad acts like disarming.Thanks!

Please post a "dump" and "diff all" of all your settings. Then we'll be able to see your settings in one place instead of just seeing snippets in dribs and drabs.

Finally everything is working fine!
Now with a failsafe test with the switch the quad returns to home like a mavic.
At channel fallback settings aux1 (arm) was set to 1000 within the disarm range.
That's why the disarm was instantly.

Thanks everyone for your help!!

That's good news Smile I was beginning to wonder if there was some kind of bug with the Betaflight 4.5 RC2 firmware, but it seems that it was just down to user configuration error.

Yes,the aux1 fallback was by default at 1000 and in my case was a disarm command.
The 4.5 RC2 Gps rescue works fine,I have also successfully added and configured a qmc 5883 magnetometer and the behavior of the quad is a lot better durring rth.

Yes I saw you had compass enabled in your settings and was going to say the usual recommendation is not to use it for RTH, but maybe you have a well working compass. BF recommends you verify this on the logs BEFORE you enable it.

Quote:
  • If a Compass (mag, or magnetometer) is available, and if it has been properly calibrated, and the data is noise free, it may improve heading estimation. Compasses must be positioned well away from magnetic fields, including those from current flowing through wires. This is very difficult even on a 7" setup. Using an incorrectly calibrated or noisy compass will adversely affect the rescue. Be sure to log your compass data and check that it is accurate and clean before enabling it. In most 5" or smaller drones, Mag is too noisy to be useful. Do not use the mag unless you log its information after flying a known 'square' course very accurately. The log should show clean 90 degree heading changes in the mag data. If not, don't use it. If in doubt, don't use it. We will be improving Mag integration in coming firmware releases.

Yes,I first tried an hmc5883 magnetometer and was not working as expected after reading the values at sensors tab. The Qmc5883 seems to working good with Betaflight and the Devs also recomend this option.

The default Stage 1 fallback setting values are "Hold" for all auxiliary channels, so I guess you must have inadvertently changed it to "Set" with a value of 1000 at some point when you originally set up the failsafe configuration.
