My first inclination is to say, no way! Don't try it. However, I have seen others take on a scale project early in their experience and make it work. So I'll start by asking, what experience with RC airplanes do you have? Include building as well as flying.
Do you understand what make a plane fly? i.e. how the controls make it do what it does?
And just how scale are you looking at? Precision? Stand Off? Or "satisfies me scale"?

It all plays into it.
