My DX6 was working smoothly, until one day I come across it and the batteries are dead and it won't start up. When I put in new batteries it when to testing mode screen (you had to flip every switch, move the sticks around, press all the buttons, and use the trims to get out of it). Once that finished, the controller restarted, and it says "Warning, throttle high", repetitively until I turn it off. I fixed this by turning on the transmitter while pressing the scroll wheel and it got me directly to the system setup menu. I turned the throttle warning to inhibit, and the warning goes away. The problem is, when I connect to a drone and my throttle is on max, the drone would explode into the air. I don't want this to happen, so are there any other solutions besides inhibiting the warning? Also, I checked, and the monitor screen says that my roll right only goes back to -58 at max, and my pitch back also goes back -58 at max as well. Is there any way to fix all of this? Thanks.

Betaflight will never allow you to arm if the throttle is above min_check. So, that is something you don't need to worry. But if your radio is randomly increasing throttle, this can be a serious problem. Sorry, I don't have Spektrum, so I won't be of much help.

My DX7S has an option to recalibrate the sticks, I would think the DX6 would too.

Oh, yes thank you so much, that fixed the whole issue.
