I hate to throw a wrinkle in it especially because I’m a newbie to this thread, but even a Cessna 172 has an artificial horizon so that you can carefully do a 30° or 40° bank or pitch up 10° or keep yourself straight and level if you erroneously find yourself in a cloud or you want to fly at night.
Makes sense, but I have never seen any model Cub with an Artifical Horizon. They all tend to use the real horizon. 😕
