May I suggest a Multiplex Fun Cub. It has a 55" wing span with flaps, uses a 10 size motor, flies on a 3s 2200 battery and builds very easy. It is docile enough for the novis and performs well in intermediate aerobatics. The large wheels allow use on any unimproved field including the beach.
There is a review on RC groups. I can't post it because I haven't met the 3 min posts.
