Builder Spotlight

Last months installment in the Composites series detailed how to do vacuum-bagging of parts at home. This month author Bob Fritz discusses how to inexpensively build one critical component in that process: the vacuum pump.

Builders share their successes.

Doug Rozendaal brings his considerable experience to a discussion of flight handling characteristics and his favorite aircraft. Among the factors designers consider are stability, control response, feel, personal preferences, FAA requirements, stick force, center of gravity, center of pressure, and the flight envelope. Every design is a compromise.
