Porterfield CP-65 Collegiate (oz8968)
About this Plan
Porterfield CP-65 Collegiate. Sport scale design by BD Mathews. Scale is 1/6. Wingspan 74in, wing area 740 sq in. Power 35 to 45 engines. Wing loading 16oz per sq ft.
Quote: "Have you ever noticed to the general public any model with a high wing, enclosed cabin, and a horizontal engine is automatically a Cub? Taylorcraft, Aeronca or Porterfield, red, blue or green; they are all Cubs. The more knowledgeable layman will even call the model a 'Piper Cub' even though the original cub was a Taylorcraft.
After many years of attempting to educate the spectators I've finally decided to give up. From now on I'll just smile and agree. When Dad says, "Son that there be a Piper Cub", don't expect me to correct him, for all I care the kid can figure maybe the old guy knows a little something after all. Nope, it's not my job man, no more hassle for me!
Therefore, this is a two inch to the foot model of a Porterfield Collegiate 'Cub'. It is finished in Cub white, trimmed in Cub red. This Cub uses a preformed plastic cowl from a Sig Liberty Sport (oz6112), pants and aluminum gear from a Sig Citabria, and features a light-ply box fuselage.
For those who know the difference between a Cub and a Collegiate I quickly add that although this model really doesn't look like a Cub, it does fly like one. It should, really, since the moments and airfoil are straight from Chuck Hollinger's Piper Cub (oz256) drawings, first published in Air Trails 1954. The design has become a near classic as it is still kitted to this day by Sig (although structurally modified).
The objective of this project was to develop a model more easily constructed than the Cub, while maintaining the same good stability and forgiving flight behavior. The resultant model is certainly different enough in appearance to avoid the Cub identity crisis and the flight characteristics have proven most highly satisfactory..."

ScaleType: This (oz8968) 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/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.

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.
