I’ve had building experience with both a kit, RV6A, and plans built, Hatz Classic. In comparing the two, I feel like I assembled the RV, but I built the Hatz. Emphasis on I BUILT.
Building the RV was fun and as has been mentioned a learning experience. The tutelage that is available on line really helped smooth out the bumps along the way. Much of the build was just following along with the manual (which was a tad sparse in those days) and employing what I found in various forums.
The Hatz has been a totally different beast and I can categorically say a total blast to build. The amount of learning experience is exponentially higher than that for the RV, involving basically every building medium available for homebuilt airplanes. Aluminum, chrome moly tube, fabric, wood, composites all are involved. I’ve learned to TIG weld, make molds for composite parts, fabric cover. It’s amazing. The biggest challenge has been that there are no instructions. You work from a set of plans, that’s it. There lies the most satisfying aspect. The challenge of seeing a part that needs to be made, figuring out a jig or process of how to make that part, implementing that process, and having resultant success is the repetitive sequence of a string of little accomplishments. It’s often peppered with failures, but that is part of the learning process. The satisfaction seeing an airplane rise up off of a stack of plans is just indescribable.
At the end of the day, looking back just before I close the hangar door, I almost always pause and think to myself, holy crap, I built this thing.
