7/8ths scale construction drawings for the Sopwith Baby and Tabloid and several pages of Narrative from Graham on his construction technique.   NOTE Graham did not build a prototype of this aircraft, and had offered these drawings with unlimited online  advice to builders who wanted to employ his construction techique.    


I can answer questions on best effort basis.    

Sopwith Twins: Baby/Tabloid

  • Grahams original comments: 

    This a 2 plane set of plans. You can combine the desirable aspects of both. The Tabloid was produced first as a Bennet racer, and did very well. It was then adopted by the military. With all of the accessories added, it needed a bigger engine, a change of cowl, and rudder to become the Sopwith Baby. Both aircraft were 2 place side by side, but in 7/8 scale they are perfect for the average 200 pound pilot of today. The Sopwith’s construction techniques are similar to the Nieuports. 


    Suggested engine choices:  Hirth with 72 inch or larger prop.  VW (with reduction )  [or Verner 5VL]   (heavier engine up front is helpful for balance  and to preserve overall appearance. 


    NOTE: The tabloid skids are necessary  with the rearward placed wheels. The wheels can be positioned as on the baby without tip over skids
