Steve Stricker's Excalibur. I don't have a photo at the moment, but somebody here might. Swept wings, jet-like appearance, originally designed for a YS120AC; so your YS 140 would work very nicely. The only problem will be to find a kit... I think I read (here on RCU) about somebody having the original molds (maybe in Maryland somewhere). There are lots of 'coming soon' teasers from classic pattern potential kitmakers who may have the molds????
There are several nice airplanes from Dick Hanson which I believe are still available from a gentleman in Utah (Elan, Excess, Ariel, EMC2).
I've always liked the looks of the Hydeout, too.
MK Blue Angel VR-7, Wild Beat, Wild Beat 777 - if you can find one...
Just a few suggestions
