Thanks for the encouraging words. And yes, it was definitely a transitional design. The last variant did not have the lower wing! That version was also used for the Zveno airborne aircraft carrier experiment. They where attached to a TB-3 bomber.Stikpusher wrote: ↑Thu Jan 08, 2026 10:40 am. And this one looks to be something of a bridge between their biplane and monoplane types.
I have been doing some research and I want to make it in the striking colours of Ivan Ulyanovich Pavlov. He was a WWI veteran and Russian Civil war flying ace. Starting with his I-4, all aircraft flown by Pavlov were painted silver, with red chassis, rudder and wing struts, a red banner with a 'Za V. K. P. (b)!' (for the A. C. (b) P. - All-union Communist (bolshevik) Party) and Pavlov's personal emblem on the rudder - a bent arrow, the former emblem of the 1-st Airplane squad during the Civil war. I already have an I-5 in those colours so I think this wil make a nice companion.
I found different profiles of this aircraft. Most important difference is the cilinder covers of the engine. The kit has the closed one as the profile has flying to the left. However, I found one photo of the actual aircraft and it has the covers removed (or maybe they where never there). So beside the spoked wheels I also got those engine covers to think about. It is a question of ease of building versus historical accuracy.
