Discontinued kit from Great Planes.

Note the plan shows a choice of wing layout, with full span wing at 76 in, optional clipped wing at 62 in.

Quote: "Introduction: Thank you for purchasing the Great Planes Piper J-3 Cub! This J-3 Cub kit is a 1/5.5 (18%) scale model of a full-size J-3 Cub and retains the real plane’s great flying characteristics.

You will find the J-3 Cub easy to build and fly, very predictable and fairly aerobatic, yet it has no bad habits. Although the model is sufficiently close to scale that it can place well in sport-scale competition, traditional Great Planes interlocking construction makes it simple to build a great-looking and straight airplane that is sturdy enough to take along every time you go to the flying field.

If you have chosen this kit as your first R/C model, it is important that you find an experienced modeler to help you throughout the building and flying of this plane. He should thoroughly check the plane over before flying it and help you with the first flights. The J-3 Cub is a big airplane and lacks the self-recovery characteristics of a good basic trainer such as the Great Planes PT Series airplanes. On the other hand, if you have already learned the basics of R/C flying and you are able to safely handle a trainer airplane, the J- 3 Cub is an excellent choice.

Scale Model Research has photo sets and drawings of full scale Piper Cubs available. These can help provide good documentation for scale detailing and contests. Their address is 3114 Yukon Avenue, Costa Mesa, CA 92626 and their phone number is (714) 979-8058.

If there is new technical information or changes to this kit a 'tech notice' box will appear in the upper left corner of the page: http://www.greatplanes.com/airplanes/index.html

Decisions you must make:

The engine you select will determine where the throttle pushrod is routed and also how the cowl is cut out, so it is important that you have the engine close at hand while building. The recommended engine size range is as follows:
.40 - .61 cubic inch displacement 2-cycle
.48 - .80 cubic inch displacement 4-cycle

Engine Selection: For the best scale effect, an OS .48 Surpass 4-cycle is ideal. For maximum aerobatics, an OS .70 Surpass 4-cycle is all the power you will need. This kit includes a Great Planes EM4070 engine mount that fits most .40 - .60 2-cycle engines and most 40 - .70 4-cycle engines.

Wing configuration: This kit includes everything you need to build either the standard or the clipped wing for your Cub. Both versions fly extremely well and are equally easy to construct. The standard wing makes the Cub a real 'floater' giving you plenty of time to think about your maneuvers. The clipped wing allows things to happen a bit quicker. Snaps, rolls and spins can be performed faster and more precisely. Either way, the model flies much like the real plane.

Muffler selection: If you install a 2-cycle engine, we recommend using a muffler that can be partially enclosed inside the cowl. The muffler shown in the instruction book photos is a Slimline #3217 Pitts Style Muffler for OS MAX .61SF and .60FP engines. If you use a OS .40SF or .46SF use a Slimline #3218 Pitts Style Muffler or similar. Most standard mufflers will require an extension to clear the fuselage sides..."

    ScaleType: This (oz13332) 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/Piper_J-3_Cub
    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.

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.
