TAIL FEATHERS
BUILD THE FIN AND RUDDER
Note: The construction sequence that
follows does not require building over
the plans. You w i l l however,
occasionally need to refer to the plans.
D D 1. Glue the 1/4" balsa forward fin piece
(F154R01) to the 1/4" balsa aft fin piece
(F154R02) so their bottoms are even with each
other.
D D 3. Cut the 1/4" sq. x 7-7/8" basswood
stick (F154R04) in half to make two fin tips
approximately 3-7/8" long . Hold a fin tip in place
on top of the fin so the aft end just overlaps the fin
TE. Mark on the fin tip where the fin LE starts.
Remove the fin tip. Carve and sand the front of
the fin tip to a round cross section but do not sand
behind the line you just made.
D D 4. Glue the fin tip to the top of the fin.
Sand the aft edge of the tip flush with the fin TE.
D D 2. Using the plans as a guide, cut the top
2-1/2" off a 1/4" balsa rudder (F154R03) with a
razor saw. Glue the top portion to the aft fin piece
as shown above. The bottom edge of the top
portion should be parallel with the bottom edge of
the fin.
D D 5. Use a sanding block with medium
(150) grit sandpaper to sand the edges and both
sides of the fin smooth. Carefully draw a
centerline all around the edges of the fin and
rudder. This will make it easier to maintain
symmetry when sanding later.
