I spent a lot of time deciding what to build. When I first saw the Sonex, I thought it was ugly and kind of disregarded it. But the more I read and researched, the more I realized that all the points Kip made are true, and the looks actually grow on you when you understand the design. Some other points:
1) The +6/-3 g limits provide a great margin of strength to the airframe, even if you never plan to do aerobatics.
2) The aerodynamics are well-designed enough to cruise at 160+mph, yet stall gently at 40-45mph. That wide a flight envelope is very rare in GA or E-AB aircraft.
3) Lots of build options...taildragger, tri-gear, dual controls or center stick, factory support for engines from 80hp to 120hp, and you can build from plans, a full kit, or subkits. You can customize to your building and flying style and preferences more than many other E-AB airplanes.
4) Efficiency. A Sonex at 1150lb gross weight has a useful load similar to LSA that have almost 200lb more gross weight. That means better performance while still carrying two people and some gear.
5) Great factory support. The tech staff really wants you to succeed and finish your build, and they really are helpful. I have never waited more than one full business days for an answer to a tech question from Sonex.
If you can manage it, I'd recommend attending one the Sonex builder workshops they run twice a year. You'll get a LOT of information on every aspect of the airplane, as well as experience with the building techniques used. And the cost of the workshop is deducted from the kit cost if you decide to build a Sonex.
There are a lot of great airplanes out there, good luck choosing one!
