A lot of guys convert their trainers over to floats for water as well as snow operation. So, get a good, reliable trainer to learn RC with then, when ready, add a set of floats and enjoy it. The benefit you will have is that you are already familiar with the aircraft performance, although it will change slightly with the addition of the floats, it will still be the same plane. Another benefit is the wing loading. It will help to have a plane that is smooth, lands slowly and comfortably for you.

Save the warbirds for after you gain a couple of years of experience. They are not trainers and do not fly like them.
