Getting a small yacht to work well is not particularly easy as a first project, especially an RC one which carries the expense of the radio gear. The Wee Nip is reputed to be a good boat, as are the many "Footy" designs, but for guaranteed performance a well reported kit is a much better proposition for a first try. All the difficult bits that could spoil things should have been sorted, and there will be plenty of experience available for you to build on.
Something like the Thunder Tiger Victoria is small enough to not be a problem storing and transporting, large enough to not be too picky about sailing conditions for a beginner, and, as model yacht kits go, very reasonably priced and a good looker when built.
