Hi all! First post on the Forum)
Some words about Grokhovsky G-38.
It seems to me, that well known plans, images and 3d model that were posted by
Redstar72 and
blackkite are fake based on pic from the TM (Техника Молодежи) magazine 08 sep 1938.

But in fact this pic described as
Двух балочный» самолет, который демонстрировался на Парижской выставке. Хвостовое оперение приближено к крылу. Этот самолет — переходная ступень к бесхвостым «летающим крыльям»
or in Eng:
Two tail plane demonstrated on Paris air show [in 1936]. Aircraft tail moved closely to wing. This plane is intermediate stage to tailless "flying wings".
So this pic is just an "author`s vision" of Fokker`s G-1 performed by A. Preobrazhensky or S. Lodygin for article.
What a Fate`s joke: real Ivensen-Grokhovsky project replaced by fake, based on picture for (again) Grokhovsky`s article.
But in article about P.A. Ivensen i found another image of G-38

And later - side view of G-38 in book
Aircraft industry of USSR 1917-1945 part I (Самолетостроение в СССР 1917-1941 том 1) ch.5 p.245.
