About this Plan

Skyranger - non-scale Auster AOP looking rubber model.

Quote: "FOR nice appearance, an aeroplane normally needs, besides attractive fuselage lines, wing, tail, and fin shapes which harmonise nicely. However, to every rule there are exceptions, and Skyranger, whose wing, tail, and fin cheerfully quarrel with each other, is actually one of the sweetest little rubber models we have seen for years. The designer produced it as a change from power flying, and derived so much pleasure from the original that a second machine was constructed and now work has started on a third, floatplane version.

Average performance with the motor shown is a little over a minute, and the best official flight to date is 1:51. However, the glide is nicely flat and numerous long thermal flights have been made. The eight-strand motor gives a scalish take-off and a long climb with a 9-1/2 in prop. The all-up weight, colour-doped (silver, 21 oz, camouflaged, 21 oz) gives a wing loading in the neighbourhood of 3 oz per sq ft, which, coupled with the simple, rugged construction, makes this a long life, low-cost, easy flying model well suited to beginners.

When selecting the materials, pick medium soft strip and soft sheet, and when building keep the tail end light - it is easier to add a coat of dope to move the CG back than to try to move the CG forward. The fuselage is built as a normal box, with formers added on top. Frequent reference to the plan, and the use of scrap card formers, will ease the cabin construction and ensure accuracy of the wing seating. Add the stringers and bind in the undercarriage before sheeting the nose with soft 1/32. The fin is cemented to the fuselage after assembly and the cabin celluloid, dowels, etc., fitted before covering.

Wing and tail are of conventional construction, the glazing of the wing centre-section being carried out after completion of all sheeting and detail work. Check all joints and sand the completed model before covering with lightweight Modelspan..."

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.
