In my experience, 90 percent of all pilots fly alone 90 percent of the time. Even twin engine planes are out there with solo pilots all the time.
The two place Kitfox has a power to weight ratio that beats all. Fuel economy, ease of construction, ease of maintenance, overall performance is not going to be found in a four place anything. Sorry, I would not even look twice. The boys and girls at the factory have a winner in the two place go anyplace, airplane.
