About this Plan

Piper Grasshopper / Piper Cub. Radio control scale model. The kit builds up into either the military Piper L-4B Grasshopper or the civilian Piper J-3 Cub. Scale is 1/6.

Quote: "...the life-size CUB being an ideal scale-subject, what you obtain with the SVENSON-kit is a model built from conventional materials with a very strong frame and an extremely low weight. The very low wing-loading of the model guarantees remarkable flying characteristics.

SVENSON chose to present the military Grasshopper version of the Piper aircraft : quite typical of that version is the famous 'green house' which offered the pilot all-around visibility. However, for those who may wish to build the civilian, better-known Cub version, we have also mentioned the necessary modification on the drawings and we have included the necessary material in the kit.

This model shoud be powered by an engine from .15 to a maximum of .40 cu in. The power necessary to fly the model being very low, we would recommend any good engine in the .19/.25 capacity-range, which will give the model a realistic 'scale' speed, with enough reserve yet for those less than calm flying days.

Although this model can certainly fly with rudder, elevator and throttle, a four-channel R/C set will allow the aileron-function

...an ideal model for the tyro and the pro alike: the beginner can safely attempt his first flights with a model that looks like a real airplane, and the pro can incorporate a wealth of details into a very realistic scale-model..."

    ScaleType: This (oz6597) 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/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.

Hi Steve and Mary. I have for the Outerzone site my PIPER J3 by Svenson with 6.5 cc Glow Engine, 1981 [see more pics 006]. See my daughter Johanna 15 months old, now she is 35 years old. Time flies. Thanks for Outerzone, my favourite site. In Dutch PROFICIAT!

Hi Steve and Mary - here is my yellow Piper, in the blue sky [more pics 007]. Built in 1982 and still flying. Photo is taken in '80s, I think 1984.

Hi Steve & Mary - here is my Piper, double size with motor of a chain saw [008, 009]. Not as amusing as a small plane. My daughter looks at the plane with big eyes. I built it in 1982.

* 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.
