About this Plan

Wedgy. Free flight gas model.

Quote: "The Class A 1940 Nationals Winner - A Little Ship With Many Unique Features That's Easy to Build. It Has Placed in All Contests Entered.

THOSE who attended the Nationals were thrilled at the sight of a small but unusually-shaped plane darting skyward with the speed of a rocket. At first glance its only resemblance to an airplane was carried out by the wings, which spread out from either side of a deep, wedge-shaped body.

It was an unusual plane, both in looks and performance. Many called it the 'Flying Wedge' and in all events it certainly lived up to this name; for it cleaved through the air with the greatest of ease, and ended up by capturing the world's record on Class A. Nor was this merely a lucky performance, for WEDGY has been winning consistently in all contests in which it has been entered.

One may look for its excellent flying qualities in the simplicity of its construction and its sound aeronautical design. The deep body helps to eliminate landing struts that cause considerable drag. The body, being shaped in such a manner that though deep, it offers small head resistance.

It has placed among the first three in every contest entered. At the Nationals it won the Class A event with a flight of 22 minutes plus. Of course the thermals helped, as they usually do. Wedgy seems to catch thermals even at sunset and many a flight has resulted in mad dashes across country.

Nine ships of different sizes have been built and all have the same characteristics - an especially tight, cork-screw climb and a tight right circular glide having great soaring tendencies with exceptional stability. Although the profile view of the Wedgy seems not too streamline, the flight results have proved otherwise, there being very little frontal area exposed to produce much drag. The exceptional flat glide indicates efficiency. The protruding wheel from the nose of Wedgy will save many props on rough landings and aid immensely in the take-offs. The new 1940 Bantam was used as power for the Wedgy although any class A or B engine would be satisfactory.

Since all plans shown for the Wedgy are not full size, they will have to be scaled up to proper dimensions. This can be done very easily on a large sheet of brown wrapping paper with the use of a ruler, pencil, eraser, patience, common sense and a couple of hours. Care should be exercised where the dimensions are concerned, since the proportions may be changed. The body should not be too diffi-cult to draw since it has only a V-shaped cross section with no formers to worry about. The wing is the simple type with parabolic-shaped wing tips. The stabilizer is elliptical and the rudder of simple shape.

Fuselage The entire fuselage is constructed of 3/16 inch square hard balsa wood, except where noted. The motor mount hearers are of pine wood or any hardwood. These are cemented to the bearer supports. The sheet balsa sides of the cowl can be built with each side. The front cowl block can be cemented into place after the fuselage sides are cemented together. Note that the top longeron is double where the wing rests on the fuselage. This is to prevent the fuselage from collapsing when put under strain.."

Update 16/03/2018: Replaced this plan with a clearer copy, re-scaled to fullsize and on a single sheet, thanks to Pilgrim.

Hi Outerzone friends, this is my Wedgy made from the oz1060 plan [main pic, 009-011]. The size is the original of the plan. Thanks for your wonderful site and for the amazing job. Best regards from Argentina,

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.
