HOME Gamely Renegade Aircraft C.V.

The comprehensive and revolutionary design of the Brevity™ is based on thorough aerodynamic and technical studies and the latest technologies in epoxy reinforeced production methods. This combination enabled us to eliminate the major design flaws inherent with most of the current models of seaplanes.

The results of these studies have accumulate in a preliminary design that addresses a thriving and expanding General Aviation market. As the concept of the Brevity™ is an evolution of an existing JAR 23 certified aircraft design, certification risks are rather limited.

Below a brief overview reveal some of the Brevity's capabilities and advantages. Also engine, cockpit and some interior features are accessible via this list.
