Re: Failsafe am I missing something?

Ok, we've all done things like that.
Not test, test, test so you know exactly what to expect from the Failsafe.
Hint: in the MWconf.exe gui you can now set the mini throttle and the FS THR from the 'SETTINGS" tab.
Do ensure the copter will decend with the FS THR value.

Re: Not usual PID question

If you just adjust the values in the MWconf.exe gui then you will see what the increment is.
But to directly answer:

The FS threshold should check only the first four RX channels.
