So, I've only just begun entertaining the idea of building an RV-10. It seems to be a great fit for all of my missions for the next 5-10 years, and maybe longer. I'll probably post a couple of threads with varying questions that I can't find any threads about (yes, I do try to search first). So this is a multi-part question. The RV-10 QB Kits for the wing and fuselage are $9,550 an $9,950 respectively, totaling $19,500. Overall, this purportedly saves between 800-1000 hours, which comes out to a cost per hour saved of $19.50-$24.37. Considering that, not including avionics, powerplant, paint, etc, this build runs right around $60,000 (a mild cost for the airplane you're getting) is the extra $20k worth it? Or is the experience of knowing every nook and cranny of the plane worth saving that $20k to put into other aspects of the build (like all the required tools...)? If you haven't built one, still interested in your input, but if you have built a Vans with or without the QB Kit, please note that in your response. Thanks!
