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
