Last year I drove from California to Virginia to start my new job.
Somewhere in Oklahoma, by the side of the road, I saw two planes sitting in delapidated state on someone's front yard. Both are pretty unique.

One is obvously two Ercoupes joined a la F-82. the other one is a weird little highly swept delta with small foreplanes, which I had never seen before. Does anyone have more info about either?

The Ercoupes bear two different fuselage numbers, so they were individual planes joined by someone, not a factory job. And no, I don't think this is just two wrecked planes someone pushed together. There are quite a few details that lend me to believe that some thought went into this, but I don't know if it ever flew.

Dear AeroFranz,
The unusual delta aircraft is the Heuberger-Rinker H-5 Stinger and love it that that this one-of-a-kind aircraft still exists in pretty good condition, Did you notice any registration? (it originally was N3638G). The Stinger was an original design of Mr. Larry (Lawrence K) Heuberger who started construction around the early-1960s. Prior completion the project was acquired (around 1968) by Mr.   
Bud Rinker (Santa Barbara, Ca) who almost certainly did some limited testing in 1970. 
Some details: Two-seat and one 140hp Lycoming O-290-G engine.
wingspan 16ft 6 inch, length 14ft 8 inch
Theoretical max. speed 180 mph, cruise 160 mph, ceiling 10,500ft and climbrate 1.200ft/minute.

Sorry no info on the twin Ercoupe
Regards, Walter (van Tilborg) from the Netherlands

Hmmm, if I had the time, money and ability I'd love to restore the little homebuilt to flying condition. Maybe the current owner can at least donate it to EAA if they're not going to restore it themselves.

The Ercoupe is...quite interesting to say the least.

Walter,
thanks a lot for solving the mystery, not knowing had bugged me for more than a year. I wonder what prompted the designer to chose such a risky configuration.

Dear AeroFranz,
My best guess is that among the many aircraft homebuilders there are a few who want to prove that  aircraft donot have to look all similar. Just think of Mr. Burt Rutan who started with his unsual VariViggen and you know what resulted from his approach.
Mr. Heuberger designed and built at least two other experimentals. The first one was the SL-1 Doodle Bug
(1954) which I would describe as conventional. Next came the Sizzler (1957) which already started to differ from contemporary designs in that is had a bulky fuselage with straight lines. At least 2 were built (the prototype N75345 of Mr. Heuberger and C-GSIM of Mr. James Sim in Canada).
For a photo of the latter please see www.aircraftworlddirectory.com in the civil section and select heuberger sizzler.
Whenever you locate other uniques I hope you will post again.
Regards, Walter

Hmmm, would it be fun to restore both of them to flying condition? :)

Maybe I need to make a trip to Oklahoma one of these days....

Just today a colleague sent me this page, which tells us that the location of the Twin Ercoupe is actually off I-40, in Tucumcari, NM (I was a little bit off! after the first 1,000 miles it all blends in!)
