So if you built and RV-8, you can continue your educational experience by welding tube and sawing wood to make the 1D you wanted. If you really want to push the envelope, there is a two seat DR-109 and a very few of those are starting to see the light of day. After all, if your RV is done, what are you now doing with all of the time you have to spare?

Best of luck,
