Stringers and Sanding 

Add the top stringers before giving the fuselage a good 
overall sanding. 

 

TAIL SURFACES 

Lay out and glue parts of the tail surfaces on the plans.  
Sand the tail parts, rounding off all edges.  Don’t add the 
horns or hinge the surfaces until after covering is 

complete. 

 

WINGS

 

Wing Construction

  

Pin down, over the plan, the t/e, l/e, spar and wing tip, 

gluing as required.  Making sure that you are using the 
correct ribs for the wing you are building, glue all but the 
center ribs in place.  With one panel on the building 

board, raise the other wing panel to allow for dihedral.  
Mount the dihedral brace in place and glue.  Sand the 

leading edge stock to be rounded and meet the ribs.
