I got into ownership of my first and current owned airplane by BUILDING it. In 2003, when I moved to MI from MT, I had been flying a club-owned Citabria into the MT's backcountry. Once in MI, I really wanted to buy a Citabria, but with limited money, I didn't want a beater and was worried about long-term airframe fatigue, etc on the older aircraft. So after much research, in 2006, I decided upon building a Rans S-7S Courier. This way, I could get a new airplane, like the Citabria, outfitted like I wanted, at a fraction of the cost. I was in no hurry and intrigued by the challenge of a build, so went for it. My wife's one condition was that we not go into debt for it, so I sold all of my toys and purchased the airframe kit. The beauty of building is you can amoritize the cost over a long period (6 years in my case), purchasing the engine, avionics, etc. as you go. My first flight was Christmas Eve day 2011.
As I read this thread and reflect back on my experience, it really is a great feeling having this plane paid for and the best part is the future O&M costs will be nominal: I will perform the annuals and all maintenance, the engine runs on mogas and burns at 5.5 gph and I will be transitioning soon to a turf strip I built, which will eliminate hangar costs.
Experimental aviation, in my opinion, is where it's at. The freedom to design, build and fly your dream plane just doesn't seem quite tangible in today's over-regulated, sue-crazy culture. My life's PhD was completing the build and cannot express the immense feeling of accomplishment and recognition received from family and friends. And now I get to FLY the dang thing! Life is good (and I should add wife is good).
So bottomline: paid cash, not rich by any stretch, made modest lifestyle choices to facilitate ownership.
