Surely, RPN is not a requirement for using AAO, but a tool to unlock the full potential. E.g. a made an aircraft script for the Twin Otter to let the prop drag (spoiler) kick in gradually rather than binary and work separately on each engine.
If you’re looking for a program to set up controller profiles and don’t have a Stream Deck it’s my impression Spad has a more user friendly UI (although I haven’t used it).
