Parasol Plane (oz9633)
About this Plan
Clough Parasol. Unconventional circular wing free flight sport model, for .049 power.
Quote -"It may look like a flying dinner plate, but this way-out model is actually a rugged performer that will draw a big hand at any flying site.
ONE OF THE MOST unusual designs in the history of aircraft is the pancake wing, a weird looking bird which actually has a number of features to recommend it.
A circular wing presents little drag at low angles of attack, making it fine for high-speed cruising. At high angles of attack the wing develops a great amount of lift and drag, perfect characteristics for low-speed landings. The sharply curved leading edge is an effective substitute for stabilizing dihedral angle.
As an extra feature on this model, 'eyebrow' slots have been added to permit climbing at steep angles without stalling.
Construction begins with the fuselage. Cut out the two sides and cement them together along the top edges, starting at the tail end and working as far forward as the strut. Insert the bulkheads and the wing strut, and then add the cabin roof cut from 1/16-in. balsa sheet mounted crossgrain. Note that the firewall must be shaped to fit..."
Quote: "Hi Steve & Mary, The original cad rendering was sent to Roy Clough for his comments. I have included them in this file. File contains the article, full size cad drawing, Roy's comments and the original scan of his drawing. Sorry about the full size cad raster, it is at 150 dpi but still readable. Lost the original cad file along with several other cad files some time ago in a computer crash. If I still had it, I could have created a higher dpi full size file. Gene"

Some construction pictures of my Parasol Plane [main pic, 004-007]. I made it slightly bigger, about 120%. The model is very easy to fly, starts from grass in just a couple of meters and can also be flown in some wind. Wing diameter: 480 mm, Weight: 290 gr, Motor: Suppo 2204/14, Prop: APC SF 7x4, ESC: 10A, LiPo: 450 mAh 3s, Servo EMax ES9051 (4.1 gr).Tomas Dunker - 11/11/2024

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.
