Air Trails Sportster (oz9197)
About this Plan
Air Trails Sportster. Free flight gas model. This is the original Air Trails Sportster design by Ben Shereshaw, as first published in Air Trails Magazine, March 1939.
Quote: "THE AIR TRAILS SPORTSTER is an efficient little gas job for small-bore engines. Although it is said that small gas models suffer losses in glides and other important performance characteristics, the difference in the performance of the Sportster to that of its big brothers cannot be denoted. Having ample wing area to take care of the larger of the small-bore engines, it is yet light and efficient enough to fly well with a 1/2"-bore motor.
This little ship is simple to build, and with a bit of painstaking care in its construction you will be well rewarded with a model that possesses a smart appearance and contest performance. Read the text and study the plans minutely before any of the actual construction work is attempted.
First select a flat seasoned workboard upon which to build the fuselage and wing. The next step is to scale all of the drawings which are quarter scale to full size. Do your utmost in doing an accurate job of this, and by all means use a set of draftsman's instruments in doing it. After the fuselage layout drawing has been completed, it is best to cut all like cross members simultaneously. The stern post should be joined first, the portion around the greatest cross-section next, and then the nose end. After allowing the assembly this far to dry..."

* 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.
