Balsa Taube 40 Assembly Manual - page 19
5.) Measure back 4-5/8” from the second aft deck former and glue
the two piece former in place on each side of the fin.
6.) Cut and glue in place the 3/16 x 1/4 x 6 balsa strip from former
F-4A to the fin. Make sure it is centered on the fin.
7.) Cut to length and glue a 3/16 x 3/16 x 10 balsa strip right
alongside the 3/16 x 1/4 piece. This piece will extend to the last
top deck former.
8.) Cut the remaining 3/16” stringers to length and glue them in
place.
9.) Put one of the tail blocks in place and mark it on the bottom
along the side of the fuselage. Refer to Photo 78 and mark the
front of the block at the 3/16” rear deck stringers.
10.) Taper the block to the line on the
bottom. Then carve and sand to the
quarter round shape as shown in Photo
79. Be sure to match it to the points on
the 3/16” stringers.
11.) Glue the blocks in place on the
fuselage sides. Use a block plane or
sand the bottom corners of the fuselage
round. Use the diagram on the plans -
“Typical Fuselage Section”, to see how
much material needs to be removed.
Fit the 1/4” square tailpost in place and glue it to both the vertical
fin and the fuselage. Be sure the 1/4” spacer is in the stab slot!
After the glue has cured, remove the 1/4” spacer. Be sure to save
the other 1/4 x 1/4 x 10 piece for the rudder post.
13.) Locate the pre-cut 1/4” sub-fin. Fit and sand the outer edge
to rough shape and glue it in place.
14.) Trim the tail post off to match the fins and sand the ends to
the same radius.
15.) Sand the LE of the upper fin round. You will probably have
to trim a little material off at the front end so it will be flush with
the center stringer.
