Skyscraper (oz8457)
About this Plan
Skyscraper. Sport model for either FF or RC.
Quote: "A 28 inch wingspan sports free flight or radio model for 0.5 to 0.75 cc engines. Skyscraper, by CA Foss.
POWERED by an AS-55 diesel, Skyscraper has proved itself to be a very rugged all-weather free-fighter with a lively performance that would disgrace many other sport models. At a handy and compact 28 in span, the total weight has been kept down to 9-1/2 oz, despite very sturdy construction.
Skyscraper is ideal for radio conversion and would easily take lightweight single channel equipment. This would not be particularly recommended for a beginner in radio, as it would prove to be a fast flyer. Details are shown for a typical installation.
The original has been flown in all types of weather and has always shown very good stability. With a 5x3 in three-bladed prop, and the motor running flat out, Skyscraper reduces itself to a tiny speck in a remarkably short time, but on the other hand, with the engine throttled back, it will quite happily potter round at low altitude.
The construction is reasonably simple, so that only brief notes are necessary.
Firstly, commence with the wing, building the two panels in the usual manner. When dry, pack up each tip 1-3/4 in, keeping the wing roots pinned down over the plan. Now build up the centre section between the two wings with dihedral braces, leading edge spars, and trailing edge. Sheet the necessary sections with 1/16 balsa, and when sanded down smooth, cover with heavyweight tissue.
Start by constructing the basic fuselage assembly comprising the two engine bearers and F1, F1a, F2, and F3, using a good strong-setting glue. Cut out the two sides accurately and attach to the .bearer assembly. Add F4, 1/4 in sq supports, and sheet the underside up to F4, remembering to include the fuselage. Make the tail skid a good fit...."

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.
