I would not sweat it that much. It happens. Hopefully you will never have to go through the "I had the transmitter set for the wrong plane" scenario. That gets interesting really quick, especially when 2 planes are setup similiar and all that is off is the trims.

In any case, you knew it was time to pack it up and that's what you did. It's better to know when to do that then to keep going and lose a plane. There's no harm in it, none at all.
