SOPWITH TABLOID & BABY

NOTE:  THESE PLANS WERE DRAWN AND OFFERED BY GRAHAM LEE ON REQUEST FROM HOMEBUILDERS WHO FOLLOWED HIS TUBE AND GUSSET CONSTRUCTION TECHNIQUE.   GRAHAM WAS NOT ABLE TO BUILD A PROTOTYPE , BUT AT THE TIME,  OFFERED THESE DRAWINGS WITH UNLIMITED AMOUNT OF HIS ADVICE TO POTENTIAL BUILDERS. 

Includes drawings for all major structures, but recommended for experienced homebuilders familiar with the GLee construction technique.   I can answer questions on best effort basis.    

 

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
