Several folks have asked for a picture of the completed biplane. For the record, it is called a Pitts Model 12. I’m enclosing two photos – one is the finished structure temporarily assembed for a "rigging check" (minus the fueslage sheetmetal), and the second is the covered and painted plane after the first flight. As far as I know, it is the only biplane out there with a glass cockpit and MEMS-based AHRS!
I can’t emphasize enough how great this was as a family project. Any skill you can imagine was required – woodwork, metalwork, welding, sewing, gluing, schematic design, wiring, painting, plating, design, and lots and lots of patience!
If people have interest in seeing other examples of the Pitts Model 12, I heartily recommend the website 2wings.com – if you look under the "airplanes" tag, you’ll see an archive of the 32 completed planes. Mine is listed as "247AG".
