Porterfield Zephyr (oz4747)
About this Plan
Porterfield Zephyr. Rubber scale model.
Quote: "An 18-inch flying scale model of one of America's most popular sport planes. Just like its brother, our 18in Porterfield Zephyr is an excellent flier because of its efficient proportions. The parasol wing and large stabilizer area make it a very consistent flier, while the general outline makes it a very beautiful model to rest on your piano, radio or shelf.
Before starting the actual construction, the plans should be carefully studied to obtain a general idea of how our Porterfield is constructed.
Fuselage. Our first step is the construction of the fuselage. Since the complete fuselage plans do niot appear on an entire page, the plans should be traced and then joined together. This not only will simplify construction, but keeps your magazine in good condition.
First lay out the two sides of the fuselage on a flat board and cement the uprights and cross braces in place. The entire struc, lure is made up of 1/16 sq medium balsa with an extra bit of cement on each joint. After you have the basic framework completed, that is, the rectangular form, you may proceed with the cementing of the bulkheads.
All bulkheads are cut from 1/32 stiff sheet balsa and are not notched except where shown. Cement the various bulkheads to their respective positions and then cement on the 1/16 sq stringers that form the turtle back. The noseblock which is carved from solid soft balsa, and cut in half for convenience in the hollowing out process, should now be cemented to the part and finished off with No.1/2 sandpaper. A 3/4 in dia hardwood noseplug fits snugly into the nose and acts as a bearing. The rear hook installation and wing mounts should be cemented in place and the entire framework sanded with No.00 sandpaper..."

ScaleType: This (oz4747) 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/Porterfield_Collegiate
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.
