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 (oz9190) 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/Douglas_A-1_Skyraider
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.

User commentsHi Steve, This Mooney Douglas AD-4B Skyraider was originally published in MB 1972-11 (it's in your RCLibrary: Model Builder 1972/11) but what you have in OZ appears to have been edited somewhere along the way, for instance the scale 'ladder' in the label is gone. When I saw the mag drawing with this scale ladder it became obvious this was no Peanut and so my brain got into Obsessive Compulsive mode. Walt says in the article this was designed to 26" wingspan in 1965, but in 72 he shot a half-scale drawing to - surprise! - 13" with a few balsa thickness changes duly noted in the MB drawing. Cheers, and thank you for your excellent stewardship :-)

Interesting. Looking closely at the two versions, I can see that this one here has some detail that the MB plan doesn't. The 'Marines' stencil on the fuselage rear is different, and all the fuse formers show wood grain that's not on the MB plan. I wonder if this is an older version of the 1967 plan, and MBs was derived later. Makes little difference, I guess. I'm tempted to scale this up and list this plan as 26 inch wingspan. It seems a more interesting (and practical) design that way.

Hi Steve, If you want to thicken the plot, I just measured the Skyraider plan in the Model Builder 72 Nov mag using the scale bar and the wingspan I get is 28", not the 26" Walt writes in the article! All I can assume is that Mr Mooney was having one bad week :-) Cheers,

* 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.
