Why a Cozy?
If you decide you'd like to have your own aircraft the options are limited if you don't have a very large disposable income. They pretty much boil down to constructing the aircraft yourself or purchasing second hand. Factor in criteria such as 4 places (or 2+2) and fast cruise speed and the second hand option quickly disappears. Also, a plans built aircraft allows spreading of the cost over the duration of the build so the ongoing expense is reasonable and realistic.
Follow this link the the designer's website for more information on the design and the reasoning behind the decision should become apparent.
Why the website?
The primary reason for the website is as an on-line build log. This will be an important part of the documentation for regulatory reasons.
Other benefits are to allow others to follow progress and as evidence of mental instabilty.
One of the most important factors in such a project is maintaining motivation; being able to look back over the build should help.
