My number is #2750. It's a lot of work, you will build a plane, not "assemble" a plane. Mine is 200HP, whirlwind 150C prop, and I bury the VSI at 4K FPM(solo and light on fuel), TAS at 9,500 is 189kts (23" map, 2500 rpm, 11 gpm). It is soooo muchhhhhh fun. Get it done!
Would I be classified as a repeat builder? I am working toward getting my airworthiness certificate for my 9A but am working on a RV12 in my garage as well. I own the 9A but not the 12 so maybe not.
