Ruppert Composite Archaeopteryx

Designed by Roger Ruppert, the 1998 Archaeopteryx was conceived as a conventional glider configuration for foot launch. Primary targets were set to minimize the mass, allowing slowest possible flight speeds and providing good manoeuvrability based on a friendly stall behaviour as well as outstanding high-speed flight performances with full fairing on the cockpit. The concept permits a safe foot launch also in nil wind conditions. Excellent climb rates and an efficient riding out of extremely weak and slim thermals (microlift) are possible.
