About this Plan
Kingpin. Wakefield rubber competition model.
Quote: "THE REAPPEARANCE OF RUBBER has revived activity in one of the most fascinating phases of our sport. Much of this activity is, quite naturally, centered on that interesting rubber-powered class - the Wakefield.
Because of the great amount of work that has been done in this class, both here and abroad,. the Wakefield model has become a highly refined machine. As such, its structure and flying tend to become rather intricate. Kingpin was created primarily to offset this tendency. To people who are short of time, inexperienced, or lazy, this is important.
It is wrong to assume that this implies a lack of thought or care in design. For example, a great deal of effort was expended in juggling the various members to get the proper cross-section, incidence angles, and clearances built into the fuselage. So don't be deceived by the ship's apparent simplicity. It is the result of thought, not laziness. It was contrived, not accidental.
The net result of all this is a rugged, dependable ship that is easily and quickly built. Many difficulties have been eliminated in the design. A definitely fixed wing and stab and a permanently mounted fin help maintain adjustments. An unorthodox fuselage structure bypasses many op-portunities for inaccurate construc-tion. A sturdy, fixed landing gear with freely turning wheels insures smooth, trouble-free takeoffs. A really flush, folding propeller keeps the blades from acting as a rudder, thereby upsetting the adjustments in the glide. Adequate provision for handling the powerful motor saves a few more headaches.
The formula for the ship's performance is an old and simple one: altitude. This requires a high proportion of rubber in the model's total weight, and calls for a weak mind and a strong back when winding. The end result, of course, depends upon the flyer's thermal-hunting ability but the height the model can reach enables him to take advantage of many of the weaker currents.
Fuselage construction is almost ridiculously simple. Notice that the longerons are laid out perfectly straight. This requires a minimum of measurement in scaling-up the plans. Begin construction by laying out the 1/8 square longerons and side stringers. Fill in the nose panel with 1/8 sheet, keeping the grain at right angles to the longerons to eliminate any possibility of splitting.
After inserting the 1/8 by 1/2 in hard balsa piece that serves to anchor the rear end of the motor. you are ready to place the uprights. All that is necessary in this operation is the placing of three spots of cement on each of the longerons and on the side stringers..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

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.
