    ScaleType: This (oz3565) 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/Waco_Standard_Cabin_series
    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.

Mary and Steve, I've attached photos of my Waco YKS-6 [main pic, 003-006] built from the Hal Swanson, Modernistic Models plans, oz3565. I'm waiting for calmer winds and taller grass to fly it. Take care,

[I wrote to Eric to thank him for his pics & received this interesting reply. Apologies for only just getting round to posting it! Mary] Hal Swanson selected some great aircraft to represent in his plan series. I was first attracted to them as a teen in the mid 70s. At that time, I don’t recall that Modernistic Models ever offered kits. The catalogs that I had only offered plans. After building a few, I suspect that he only offered plans. Each of the plans that I’ve built required some additional “engineering” to make the model work. The parts are typically about 90% correct. They are the kinds of issues that would have been worked out prior to offering a kit. So, I’m not sure if the “kit” designation on the plan description on the website is accurate. Of course, I could be wrong, just my thoughts. All that being said, Hal’s plans are definitely worth the extra effort. They result in lovely models of interesting aircraft. I would be curious to hear from other modelers and their experiences with Modernistic Models

A note on the plan stating "1:48 scale" is incorrect. A full scale Waco YKS-6 has an upper wing span (in round numbers) of 33 ft. At 1:48, this would result in a model span of ~8.25 inches. The model span is roughly double this number, thus the scale is ~1:24.

Good point. Checking the dimensioned prop at 5 inch (and main wheels at 1 inch) the plan is scaled correctly, the total wingspan is ~16.6 in, so the printing of "1:48 scale" on the plan is a curious mistake.

I think the solution is at the root of designing.
What kind of Waco YKS-6 3 view was avalaible in 1968? Paul Matt's wonderful 3 view dated 1965, "casually" has the same identification number... What about the scale drawings? "Casually" 1:48 scale. Many Matt's plan are mixed 1:24 and 1:48 in the same plans. Probably for a mistake was reported the original scale on the label. Pit

Further to Eric's comments, I agree that Modernistic Models plans had to be approached carefully. On this Waco plan, if you measure (on the front view) from the centerline to the wingtip (top wing), the half span is 8.3." The title block indicates the model wingspan is 16-5/8." Yet, if you add up the wing panel lengths (plan view) and add the fuselage width (dictated by the bulkhead dimensions), the total span is slightly over 17." Even allowing for "round-off" and effects of dihedral, this seems to be a curious discrepancy. Such are the peculiarities of pre-CAD, hand drafted drawings!

Yes, such are the peculiarities of pre-CAD, hand drafted drawings indeed! We can however only take our hats off to the wonderfully talented designers/draughtsmen who gifted us with these treasures !! Try matching 2 symmetrical halves of a plan with modern tools and one wonders how we ever got them to fly, yet many of us have for decades :) As someone commented elsewhere, these were never intended to be engineering drawings. Simply workable treasures, respectfully appreciated and enjoyed !!

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.
