Mike;
One was done by Jack Sheeks, it was featured in Flying Models 7-70. It had a 58" Wing span. The plans were CF 212 and may still be available. One other that I know of was done by Hi Johnson, maybe Jim Ivey will chime in here and give us more info. Both of these featured "Bent Wings"
"Billy G"
More search has found that the Hi Johnson "Stuka" was featured in the MAN Annual 1960, plans are available from Barry Baxter. It had a 59" Wing Span and according to Barry no flaps?
