Good afternoon! Please forgive me for disturbing you! My name is Vladimir! I'm from Russia. I love gliding. I dream of building a glider myself. But I do not know how to design, so I'm looking for a ready-made project. On the Internet I found your wonderful project D-43. As I understood have D-43 18 meters scope, but you have developed project 20-meters with winglets. Tell please not sell whether you project documentation on D-43 20-meters with winglets? With best wishes Vladimir!
