About this Plan

Yak 3. Scale model Russian WWII fighter, for radio control. Wingspan 1090 mm.

Update 6/12/2025: Added article, thanks to RCYeager.

Quote (google-translated): "Many modelers welcomed the blueprint of the small Tony model - at least according to numerous letters from recreational modelers. In a number of letters, there was a wish to create a series of blueprints of such small RC semi-scale models of well-known and successful military aircraft, similar to the recently published 'SUMek' blueprints.

The second in line is a model of the Soviet Yak-3 fighter from World War II. A three-view drawing, photographs and a description of the real aircraft were published in the magazine Letectví a kosmonautika 9/1974.

The Yak-3 model cannot be built and flown without sufficient practice. The construction requires a lot of patience and care - symmetry, especially of the wings, is a basic prerequisite for success. When flying, the pilot does not have much time to think about which way is left and which way is right.

Given the small dimensions, the model is relatively fast. With an engine of displacement 2.5 to 3.5 cm3 and controlled by an RC kit with four servos (rudders, ailerons and engine), the model is capable of flying basic aerobatic maneuvers. However, the small Yak-3 flies with three servos.

The construction is mainly made of balsa, then plywood, pine strips and other common model building materials.

The fuselage of the usual construction with sidewalls is built in an inverted position on a workbench; the upper rounded part is glued to it additionally. The cabin canopy is made of a modified molding of the Model cabin.

The wing is one-piece, built of three parts. It is connected to the fuselage with a pin and a plastic screw. The leading edge part up to the spar and the middle part of the wing have a rigid balsa cover, the entire wing is covered with paper..."

    ScaleType: This (oz1093) 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.

    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Yakovlev_Yak-3
    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.

Hi Steve... since you were given all this new information, might as well have the published date, which is June of 1985. Will send you the article by e-mail, from which you can grab a couple pics.

Notes

* 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.

Scaling

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.
