Not too hard? Well, yes and no.
If you are designing one as a one-off for to build yourself it's not that difficult if you have a bit of experience with model aerodynamics, drawing skills, (Even if you use a computer.) and a lot of patience. However, if you are designing one as a kit to be built by others that is another issue entirely, especially if you want to make sure that any average modeler who builds it can get it to fly.
Does that answer your question?
