Thats it exactly ! You won't need to be all that low. You start your decent after the turn to base. By the time you turn to final, you should be about half as high as you were on the downwind, maybe just a little higher than half. It really depends on the size of your pattern and the amount of wind, etc.
Learning to fly models is a series of break throughs alternating with a series of plateaus. Its during these plateaus that we realize somethings we don't understand ,yet. Or somethings we just haven't perfected ,yet. Please don't be discouraged by the plateaus. Its during the first or second plateau that many people become frustrated with the hobby and leave. But really, the layers of complexity, or the onion of understanding, is the remarkable aspect of this hobby . ANd it can challenge a person for their entire lifetime Its a great hobby!
Learning to land correctly is generally the new pilots first taste of "learning, while on their own". (And first plateau.) Your instructor walked "with you" through the basics. But now you will spend the rest of your life learning and talking with other pilots and comparing notes with others and practicing and reading articles and so on and so on. It never ends. You will always be learning something new. At least thats how its been for me. And just because you are flying and landing on your own now , you can always ask your instructors or other experienced pilots for explanations and tips. And don't be surprised if your knowledge one day exceeds that of the people that helped you in the beginning. That happens. But for the most part, clubs are an information sharing community. The club tends to grow smarter as a community. Good info is shared and bad info is discarded. And the group learns together. Well, I have really diverged off topic and into Zen and the art of aircraft repair. But it might be helpful to see where you now stand in the big picture. At the edge of a plateau.
