For the money, it's hard to beat the RTF's. Here in the states you can get them through George Cleveland. See: http://pages.prodigy.net/gcleveland_...els/index.html
For plans, try Barry Baxter, looks like most of them are vintage - See: http://www.controllineplans.com/frameset2.htm
I fly a RTF Yuvenko F2D wing with a Norvel 15. It's a fun combo for sport flying, no way could I keep up with it if it had a true F2D motor!
