Oh Boy.......
adding weight is never the best option to improve performance.
Adding weight to a plane that already lands too fast is like adding fuel to a fire.
Try making the plane lighter by substituting lighter onboard equipment and also work on moving the CG back in increments until you can flare the model on a deadstick final.
Naw, I have to disagree...
I have been a long-time proponent of adding weight to planes. A plane has to be light to fly, but "light" is a subjective term. How light is light?
Well... It has to be lighter than a battleship for sure, but like everything else in the world, people take things to extremes. A thick shake should be thicker than milk, so some people come to the false conclusion that "Thicker is better". So now, some fast-food restaurants make shakes that are so thick you can't suck them through a straw! That is not better!
Every airplane has an optimum weight - and even that will vary from one pilot to the next. Just because mine is lighter than yours doesn't mean it's going to fly better. I have built 5 versions of a particular airplane (The Great Planes Ultra Sport). On onee of them, I went through a lot of trouble to make it really light. It still flew well, but not nearly as well as the other four.
So, by all means, add the weight - they put it there for a reason. And, as it's been said, a nose-heavy plane will have a hard time slowing down, so when you add the weight, re-check the CG.
