If you trim for straight and level flight hands off then you can just land and see where the elevator is sitting to get an idea of how your CG is set. I use the dive test on my pattern planes but the reason for the tucking is how the trim is on the elevator so it tells you the same thing. There are several ways to come up with the same answer. I still use my old trim chart I have had for years, I see new ones come up all the time and try using the new improved ways but they all seem to work out in the end. Like CG mentioned, just watch out for tail heavy, it's a real thrill!! I was always taught to trim at full throttle but I started to trim at half throttle and my planes fly a lot better FOR ME these days. In time you will find the method you like best for yourself.
