Design and development

The Silent is a conventional composite monoplane glider with a retractable 13 kW (17 hp) electric motor driving a 1.92m propeller. The aircraft was originally marketed with a nickel–cadmium battery pack, but in 2005 this was replaced with a lithium polymer battery system that gives three times the range of the early installation.
