Scorpion (oz8179)
About this Plan
Scorpion. Free flight sport model for .049 power.
Quote: "A low-wing free flight model is a rarity. For proof of this fact, build one yourself and take it out to the local flying area. At least six people will ask you what kind of U-control job you have, and a dozen more will bet anything that it won't fly. This is the experience we enjoyed with the original Scorpion.
This ship is a natural for excellent sport performance. Stability, realism and ruggedness are its main features. The climb is realistic; R.O.G. characteristics are very good; the glide is slow with a moderate rate of sink, and it can bounce off some big trees and come up fighting. What more can you ask for Sunday flying?
All sheet-balsa construction is utilized in the fuselage and tail surfaces, thus offering the best strength-to-weight ratio possible in a model of this type. The wing is quite conven-tional and of the most elementary but strong construction.
The drawings are half size for engines from .035 to .049 displacement. For those of you who want something for .099 engines, simply enlarge the drawings to three times the size shown on these pages.
Building the Fuselage: First, cut (2) sides from 1/16 hard sheet balsa, then, cut (2) nose reinforcement pieces shown in shaded outline, from 3/32 sheet balsa and cement them to the sides, making certain you have a right and left side. Cut out (1) each of all the formers shown on the plans. Cement formers No.1 and 5 to the sides, align properly and allow to dry. Now cement the remainder of the formers in their proper location.
Drill holes in the firewall to suit the engine of your choice and bolt the engine in place. The nuts should be soldered to a piece of sheet brass which in turn is glued to the rear of the firewall.
Bend the landing gear from 3/32 wire and sew to former No. 2 with soft copper wire..."

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.
