Do you want built up balsa? If so, check out the threads here on the Widebody 60 and the Epsilon, both by Columbo Anderson, available from Pattern Pros--
http://www.patternproz.com/planes%20ca%20model.html. These kits have pre-built balsa sheeted foam flying surfaces, which makes the construction almost foolproof.
Or do you want fiberglass fuselage & foam wings (unsheeted cores)? If so, see Precision Aero Composite--

The Columbo Anderson products are very popular, first class designs, first class flyers, reasonably priced. The PAC line includes the classics of yesteryear along with very competitive modern designs. There is a steep learning curve for the first-time builder of this type of kit. The PAC crew are very good at helping you make a choice of kit, advice on building, choosing powerplant, etc.
