Occasionally it will switch into Loiter/Hold, but most of the time it switches to Land. And when it does switch to land the Pixhawk Mini starts flashing PURPLE and beeping. Which means that it doesn't have GPS lock. This is interesting though because in all other modes Stabilize/Altitude it pulses GREEN, which indicates that it does have GPS lock.
I'm currently using the single channel flight mode. I'll attach a photo. They correctly are highlighted when I switch channel 5 between the three.
As for Kill/Acro on Ch 8, most certainly not, I only wanted to have my kill switch on Ch 8, which I thought was indicated in the screenshot. I'll have to look into that.
How did you see that Ch 8 was Kill/Acro?
