Koolhoven FK-58 (oz421)
About this Plan
Koolhoven FK-58. Free flight scale power model, by Alan Booton. Originally printed in Air Trails 1939 (see article) this is a later reprint by Golden Age Reproductions.
Quote: "THE Koolhoven FK-58 is a new Dutch fighter similar in appearance to many American sport planes, especially the Warner-powered Ryan SC. Four machine guns are carried, two in each wing beyond the landing gear retracting mechanism, and there is a small bay in the fuselage bottom in which light bombs may he carried.
The model is to scale, except for the flying propeller, and duplicates the prototype in miniature as to lightness, speed, and grace.
Fuselage and cowl. Prepare a 6 x 8 in plywood sheet by cementing 1/32 x 2 in sheets together, cross-grained, and let dry several hours under the pressure of books or other weights; then cut out all the formers except those noted.
Only the left side of the fuselage is built on the plan. This includes only the three 3/32 square longerons and the short 1/16 square piece and the formers. Pin the top and bottom longerons and keel form over the drawing (waxed paper between) and cement the formers over their respective stations. Where no longeron is present under a former, block it up the proper distance. (A coat of cement on former C where the bend is to come will probably make the bend just right.) Prebend the mid longeron and cement it in place.
When dry, remove the left half from the board and build the right half up to the same stage directly to the left half, then cover the front with 1/32 sheet as indicated and run the bamboo sliver fairing strips onto the rear. Rubber bands will hold the strips while they are being lined up to the dots on the formers..."

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 (oz421) 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/Koolhoven_F.K.58
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.
