My cost..25K
My -4 build was done on a very narrow budget, and not many have done it as cheap I'm sure. I have a lot of experience in the Aviation maintenance business and did everything myself except sew the seat covers. I built my engine from a run-out core, did all my paint work, not fancy, Steam gauges, fixed pitch wood O-320H2AD, 160 hp. Electric flaps, ail/elev trim. I bought all my kits new from VANs in the mid/late 90's. I have almost every receipt from the almost 15 yr. build, and I'm right at 25K. I couldn't likely do it again unless I bought older kits, as the price has gone up. My kits totaled 10.5K I beleive.
