Sad to see the legacy kits go away, but the "modern day" builders have it quick and easy, so that's what sells. As others mentioned, us pre-internet folks that built 3's,4's,and 6's were enamored with the VANs kits and plans in comparison to any other experimental that even came close to the RV look and performance. You had the Thorp T-18, Mustang II, or a BD-4 as the other similar (metal) choices. To me, building my RV-4 was an experience that I thoroughly enjoyed, and the 40 some plans sheets and builders book were ample to get the job done. I sometimes find in today's world, the internet search and options slow the build technically and the "buy it now" button is great for the deep pockets, but not the simple DIY craftsman. I started my -4 in 1993, and ALL the kits including finish were around 10K. I built my own engine up from a give it away run-out O-320H2AD and have 6.5K in FWF. A $200 Sterba prop off Ebay I re-finished still drags me around. In total I sit at 25K ish total investment including my DIY paint job. I want to build another plane someday, but I can't see affording it. There are few unbuilt/unfinished kits popping up, but you gotta be quick to snag one. For you guys battling the Governor bumps, I had a bump on each side of the H2AD, one for governor, and one for fuel pump. I machined off both of them slightly and made an angled cover plate for the pump, and the governor boss was never internally finish machined from Lycoming, so I shaved it too, no cover needed. Didn't take much to avoid a "bump". You can see the fuel pump cover in the pic.
