Sopwith Tabloid


by Jim Pollard
December 12, 2004


The Sopwith Tabloid design actually pre-dated WWI as a racing and "sporting" machine. The original design featured lateral control via wing-warping and forward extending "skis" on the landing gear, apparently to prevent nose-overs. It was a significant advance over the open framework types like the Curtiss Pushers, Farmans, and the like, and the British Ministry of War began buying them for the embryonic Royal Flying Corps even before the war broke out.


Later versions of the Tabloid featured 'V' strut landing gear and ailerons. A number of armament experiments seem to have been tried with the plane, with machine guns bolted on in several different positions. This was before the development of interrupter gear, so none of these were really satisfatory. Tabloids figured in on one of the first successful bombing raids, being used for the destruction of some German Zeppelin sheds. The aircraft were rapidly overtaken by the advance of technology, and were out of frontline service after 1915.


I found a very nice 3-view of the "Scout" version of the Tabloid in the February, 1992 issue of Scale R/C Modeler (now defunct, I believe). Enlargement in a photocopier yielded outlines over which I could design the structure. Nothing here is too sophisticated. The hardest part probably being the nose cowling, carved, sanded, and hollowed from balsa block.

 
 


Tissue was pre-shrunk on a rectangular frame, applied to the structure, and shrunk again. This did NOT remove all the wrinkles, but looks better, I think, than un-shrunk tissue, and did not warp the lightweight structure. The "aluminium" colored cowling and forward fuselage is airbrushed Model Master Metallizer Lacquer, with a clear coat of sprayed Krylon on top. The rest of the markings are cut from colored tissue paper, except for a couple of access panel markings and the "Sopwith Aviation" legend on the vertical stab, which were drawn by hand with a Sharpie pen.

 



Tires are sanded to shape from styrofoam obtained from some dark gray trays containing mushrooms we got at the supermarket. The hubs are simple paper cones. The "Lewis gun" is scrap balsa, wire, a length of 1/8" OD aluminum tubing, and some strips of paper.
 


The original "paddle blade" prop blades were formed from 1/64" plywood. I soon discarded this for a plastic Sleek Streek prop that seemed to work a little better and had some of the nose weight the plane needed.
 

There's about a gram of lead from a fishing sinker, cut in half, glued inside the cowling to bring the CG to about the point of the upper wing main spar. I don't have a scale, so I have no idea what it weighs. It's no 6-gram featherweight, but with all that wing area it still floats along SLOWLY with a motor of 1/8" rubber strip.
