About this Plan

Curtiss JN4D-2 (Curtiss Training Plane). Three foot span rubber powered scale model.

Quote: "HOW TO BUILD AN 'IDEAL' CURTISS Training Plane (JN4D-2) Three-foot flying model. This model is a scale reduction, 1-14 full size, of the well known JN4D-2 training machine. It is the most universally used and best known American aeroplane. We guarantee it to rise from the ground and fly by its own power, provided it is constructed strictly in accordance with our drawings and these directions, and with Ideal Model Aeroplane Supplies. As this model is made with the same kinds of material, with the same parts and, on a small scale, in the same manner as the large airplane, the constructor will receive an excellent general idea of modern airplane construction that will be highly educational, and that can be obtained in no other way. - Copyright 1920, by Ideal Aeroplane & Supply Co, New York NY."

Direct submission to Outerzone. Note this plan is at half size, as originally printed.

Update 06/04/2014: Replaced this plan with a clearer copy, scanned from an original Ideal kit plan and contributed to Outerzone by Jeff McCammant, Story City, Iowa.

Supplementary file notes

Instructions, complete, 6 pages of text. Also an alternative version of the orignal plan which is exactly the same but scaled to full size at 38in wingspan.


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 (oz3740) 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
    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.

* 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.
