Arup S2
Does anyone have information regarding this plane??
It is a Golden Ager (1930's) and was commonly called the "flying billboard".
It is a low aspect ratio "reverse" flying wing (straight LE with an oval shape).
I only have a few pix, but need to know the WS and length to begin scratch-building.
Any help on this would be greatly appreciated.

Arup S2
I remember the airplane from the 30s. Seems it was also called the flying pancake. Try Bob Banka or any of the other scale confirmation outfits. These guys have something like 40,000 or more pictures, three views and the like. Someone should have the information you need.

Arup S2
Hi Viper Pilot,
I am in the process of building a near-scale model of the Arup S2. I have been looking at this aircraft since I first read an article by Bernard L Rice in the English magazine Aeroplane Monthly of July 1979!
Can't hurry these things!
The measurements in this article are scant but give a wingspan and chord of 16' with a span of 19' over the winglets. Try as I might I couldn't get the shape "right" with those dimensions so I have come up with what looks like a satisfactory compromise.
I am building in roughly 1/4 scale and have come up with a span of 48'' and a root chord of 33" the fuselage width is 4". There are 6 ribs in each wing some will be ply the rest balsa. I am planning a multi-spar construction the spars will be wooden dowels of various diameters.
The winglets/ailerons will run on replaceable c/f arrow shafts and there will be a couple of thin music wire skids under the tips to afford some protection fot their fragile placement. Covering will be Koverall and dope. Control by JR 642.
I am presently mulling over the U/C design. I live on a rural property of 33 acres some 130 kms north-north-west of Brisbane in Queensland, Australia and have my own rather rough landing strip. I have to put oversize wheels on most of my aircraft but even so have constant U/C problems. My current Astro Hog! (I AM 65!) has 4.5 inch airwheels and is just about able to cope so that is likely to be the fitment on the Arup. I am actually toying with the idea making a set of oleos from K&S tubing, just depends on how inspired I get. Happily I have metal shop facilities as I am retired toolmaker. I spent 26 years teaching engineering trades in a Sydney technical college and for the last 12 years had an electronic repair business in Brisbane.
Hope that gives you some help, I have based all my research on the 6 photos which accompany the original article, if you come up with anything else I would appreciate you letting me know.
I don't know if you have seen the article but Bernard Rice has built a full size replica of one of the Arups for a museum in the US just recently. I have not been able to find him on the net but there was an article about the project in a Kentucky newspaper some time in 2002. Also if you have FMS (the flight sim) on your computer a Japanese guy has produced a model of the Arup S2 for it. If the real one flies as well as the sim I will be very happy!!!
Cheers for now,
Joe
I have used the scale section (naca M6) drawn on the program TracFoil available from the net. I have draughted it all onto a slab of craftboard, which will also be the building jig. I am planning to use a Saito .65 for power.
