I would go a step further and say flying without training (let along flight testing without it) is pretty close to the dumbest thing a person can do in aviation and perhaps is almost borderline suicidal. As you (Bill) pointed out, test flying without an idea of the basics of flying an aircraft that has been proven to be stable and easy to handle is a good way to find yourself in a predicament that causes the "deer in the headlights" reaction. Norm, get some flight training first. In an ultralight, it's not that expensive and it will pay huge dividends not only in terms of safety but also it will help you rationalize choices that have to be made during the design and construction of an aircraft. It can also help you to have the insight necessary to pick up when something just isn't "right" during the construction. Money spent on training is seldom ever wasted so long as one approaches it with an open mind and a willingness to learn.But doing the test flight without flight training probably is foolish, in my opinion.
