From KAVAN RC Wiki

In the middle of 1990, a young Czech company called HPH (already established as a museum quality scale model manufacturer) restored the production of one of the latest sailplanes designed by the Glasflügel – Type 304. The manufacturing plant in Kutná Hora (central Bohemia) started with the HPH 304CZ built using the original moulds and jigs, later upgraded to 15 metres FAI class HPH 304C Wasp. In 2006 they introduced a brand new 18-metre-class design named HPH 304S Shark and finally the 20-metre two-seater class sailplane HPH 304TS Twin Shark in 2017.
