I'm trying to swap throttle/strafe to right stick for... pitch/turn over to the left stick.

Every time I try, receive a weird error message stating the following and it's not allowing me to save:

vo/if_help_gamepad_new_editable1.lua:375: attempt to index a nil value

stack trace back:
vo/error.lua:71: in function <vo/error.lua:70>

Also, iOS Air Pods not working with your game for some reason.

FWIW, I get the same error. iPad Pro 10.5, iOS 11 beta 10.

Thanks for the report. I found the problem and it'll be fixed in the next update.

I don't know why your AirPods are not working. We'll have to get a set to test with.
