Nikitin Shevchenko IS-4 (oz1444)
About this Plan
Nikitin Shevchenko IS-4. Free flight rubber scale model of the Russian experimental polymorphic fighter.
Quote: "The last of the Soviet folding-wing fighters is inherently stable with low drag and good moments, making it a fine project for WWII combat events; this one qualified at the FAC Nats.
Among the many pleasures of modeling is the ability to create a flying replica of an obscure or experimental aircraft. Watching such a craft take wing provides insights into what the designers and engineers of its full-size counterpart must have felt watching their creation as it flew. The subject of this article was just such a unique project, a short-lived but attractive Soviet fighter that reflected the conflicts among its creators.
The high command of the Soviet Air Force remained enamored of biplanes long after other air services had abandoned them in favor of the sleeker monoplanes. Such was the intensity of the biplane-monoplane controversy, that a series of peculiar aircraft was commissioned that could be flown in either form. These 'folding fighters' were designed in such a way that the lower wing could be retracted into recesses in the fuselage and upper wing, thereby allowing the maneuverability of a biplane or the speed of a shoulder-wing monoplane as the circumstances required. This early example of variable geometry was eventually dropped in favor of more conventional configurations, notably the low-wing monoplane.
The last of the folding-wing fighters was the Nikitin-Schevchenko IS-4 (named for its principal designers). It is an ideal subject for a flying model because of the inherent stability of the shoulder wing in the monoplane configuration, the narrow frontal cross-section afforded by its water-cooled engine, and good nose and tail moments. Photographs of the IS-4 have never appeared in print, but a good 3-view and perspective drawings were published in Soviet Air Force Fighters Part 1, by Green and Swanborough (Arco, 1977). The real aircraft did indeed fly in the summer of 1941, but appears to have been abandoned in the face of the rapid advance of the Wehrmacht.
My 18in span model was specifically designed with mass-launch WWII combat competitions in mind. Most of my low-wing model fighters have exhibited suicidal glides once the power ran out, so the Chambermaid-like proportions of the IS-4 had an irresistible appeal. The model recently won the WW II combat event of the Glastonbury Connecticut modelers and was one of a dozen models to qualify for the event in the 1980 FAC Nationals. It is an extremely stable plane that regularly turns in times in excess of a minute..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz1444) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Nikitin-Shevchenko_IS
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.
Do you have a photo you'd like to submit for this page? Then email firstname.lastname@example.org

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
