There is no shortage of plans or balsa, Cya and covering for those who really like to build but aren't all that fond of the quality of the kits any more than the ARFs or RTFs. Building from plans just reqires a bit more cutting of the wood than a kit. There are plans for almost any type of aircraft the you could ask for. Just be careful which ones you buy and be sure they are from a reputable builder.
Until the advent of laser cutting the die cutting of balsa sheets was pretty crude. This is still true of most of the plywood. If you really want to build - buy some plans. The John Pond collecton is now available from AMA.
For all you ARF or RTF pilots who just like to fly but can't, or won't, build, pay your club and AMA dues and go to the field and fly and have fun.
