Direct submission to Outerzone.
Update 4/3/2023: Added article, thanks to JeffGreen.
Quote: "The accompanying drawings are for a model with a span of 2 in and dimensions given in coresponding scale. Increasing all dimensions by one-half will produce a very good fling model of 36 in span, which will out-perfom the smaller ship in every way. Limited space does not permit printing plans of a model this size, full scale.
A careful study of present model contruction has proved that constructing fuslages in halves ( a left half and a right half) is not only the most accurate method but also the easiest and strongest. Therefore, the 'teardrop' fuselage of the Crusader should be constructed by cutting left and right formers F-1 to F- from 1/32 sheet balsa according to patterns K-1 and K-2..."

ScaleType: This (oz907) 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/American_Gyro_AG-4_Crusader
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.
Do you have a photo you'd like to submit for this page? Then email admin@outerzone.co.uk
User comments
Hello Steve, I'm currently building an enlarged 36in rc version of the Crusader at Wattflyer: http://www.wattflyer.com/forums/showthread.php?t=69248 The plan is not 100% accurate, as there are some discrepancies between views, and the fuse former ears which create the wing farings do not place the wing at the correct location on the fuse, as the wing TE is located above the fuse bottom. Still, it is certainly a workable plan for creating the fuse and providing a good starting point. I have attached a photo of the main fuse, before the modifications began. Feel free to add it to the Crusader plan, as it will at least provide some photo of the construction.Bill_G - 14/01/2013
Photo of his completed model now added, thanks to Bill_G.

Dick [unclear] is undoubtedly Dick Gleason (deceased) of Austin, MN, USA.

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.
