About this Plan
Pay Up. 1/2A size PAAload free flight model.
Quote: "Always among the top three winners in the 020 payload event, this model
is also a delightful small-field sport flyer.
Simple to build and fly, Pay-Up makes it easy to win contests or to enjoy a good day of sport flying. The characteristics of this PAA Load Class model make it an excellent choice for use by the beginner for fun, or by the expert for contest work. The 1/4-A engine is easy to start and operate. With its limited available amount of power, it is imperative to quickly clear the ground on ROG and gain altitude as fast as possible. After attaining good height, an excellent glide is required to be competitive. A side benefit is grooved, steady, smooth climb which lets Pay-Up get as high as most of the smaller PAA Load models.
This model borrows heavily from past successful designs. The wing planform and construction is recognizably Mathis. The stab construction is split rib type and fuselage construction is the old standard box type.
Moments and force arrangements were arrived at through the trial and error method—over a period of three years with four different models. The combinations appear to be right, for this model and its predecessors have never failed to place in the top three in any contest entered. Awards received include two won in small field 'fly-for-fun' contests. Any 1/4-A engine may be used, but fuel shut-off and a dethermalizer should be employed even if flying only sport. Too many sport models have been lost because of the lack of either one or both of these items."

* 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.
