About this Plan

Whizzawing. Free flight gas model. From December 1943 Flying Aces. The Whizzawing, a free flight power model by Hal deBolt. Span is 42 inches.

Quote: "THIS SERIES OF models was first conceived in 1940 with this theory; the more altitude you can obtain in a given length of time, the longer it will take you to come down and the chances of catching a thermal are just that much better. With this in view the entire model was designed with an accent on climb. In doing this however we kept in mind the fact that you must still have a decent glide.

In the first place the design incorporates a low aspect ratio wing to cut down the drag, and an airfoil possessing splendid climbing qualities. A planked circular fuselage with an exceedingly long tail moment arm was used to reduce the resistance and to insure a steady course even in rough air. To this we added a lifting stabilizer with a thin airfoil to keep it from looping without adding too much resistance.

When you put it all together you get a very stable model with an amazing climb. You will find that a model of this type requires a bit more time to build than most jobs, but I firmly believe you will be amply rewarded with the prolonged life span it will have.

Wing. The wing must be constructed first because it is impossible to complete the fuselage without it. The wing is a simple single-spar structure of conventional design to which spoilers have been added. You may start by cutting out the ribs with a template using the stock indicated on the drawing. From then on build it just as you would any other until you come to the sheet balsa covering. Before this is installed you must install the modified timer and spoiler mechanism.

Take some .032 wire and 1/16 aluminum tubing and proceed to bend the wire parts to shape mak-ing sure that when a piece of tubing is required you place it on the wire before the next bend. Install the parts in their required places on the front side of the wing spar, being sure to cement the tubing well. Check to see that all parts move freely and proceed to cover with sheet as indicated..."

Quote: "Here is Whizawing in a plan for building. I kept the original artwork but re-arranged it to fit into a buildable plan small enough for output on a standard 36 in wide format printer. Hopefully someone will tackle 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.
