Don't make performances secret this time

The data is not from somewhere, but from the russian book

М. Маслов "Истребитель И-16" - M.Maslov 'I16 Fighter'

Mr. Maslov used in all probability the same sources as Oleg does too -
'Samoletostroenie v SSSR. 1917-1945 gg.' published by the TsAGI- Soviet central aerodynamical institute, and the 'History Of Plane Construction in USSR', by V.B. Shavrov.
If you like that more, i could give you an excerpt from the later book, too.

Even without that much reading, one who has an idea of the WWI plane performances would recognize the 21m/s climb ( or 24 as it earlier was) as wholly unrealistic number.
Contemporaries of I16 type 24 with the engines of about 900-1000 hp had climbs of about 15 m/s at most. For the climbs over 20m/s an 1500 HP + engine was needed.And that means La5/7, or 109G, etc. The value is typical for the mid and late war planes.

And I ll be surprised if all this changes your opinion
