I think we now agree, Су-27, and Sobolev is right (he’s a serious historian). The photograph of what he calls the Grade-1 is in fact the 1908 triplane.Just one error or typo where he states B 1902 г. он начал строительство самолета. This is impossible: in 1902 Grade was still a student at the TH Charlottenburg, and after his studies in 1904 he began at first building his two-stroke engine which led to the foundation of his Motorenfabrik in 1905. Only in 1907 began his interest in aviation, and in Summer 1908 he began the construction of his triplane.I also have a copy of Sobolev’s Рождение самолета, but I hadn’t seen it for years… Thanks to remind me…
