Read   this   instruction   guide   carefully 

several   times   before   starting   the   actual 
construction   of   the   model.   You   need   to 
familiarize yourself with the overall flow of 
the process, since there will be many starting 
and   stopping   points   for   various 
subassemblies.   There   are   many 
opportunities   for   overlapping   the 
construction   of   one   subassembly   while 
another   is   drying,   even   if   the   instruction 
guide doesn't explicitly show this. Reading 
these instructions ahead of time will allow 
you to understand what needs to be done and 
when,   and  it   allows   you   to   schedule   your 
building time more productively.

Step 1

    Test-fit   the   pieces   together   and 

make minor adjustments as required for the 
pieces to fit friction-tight, but not so tight 
that   the   pieces   are   damaged,   not  so   loose 
that the pieces fall apart.

Step 2

  The two large end pieces should be 

spaced   about   2”   apart,   with   the   tubes 
holding   them   together.   One   of   the   end 
pieces should be about 1/16” from the edge 
of the tubes, and the other end piece about 
2”   inward   from   there.   Insert   a   1/8”   balsa 
spacer between the tubes at each end piece 
to   keep   them   properly   aligned.   Slide   all 
three of the movable small end pieces onto 
the   tubes   at   the   far   end   and   space   them 
about 1” apart.

Step   3

    Insert   a   scrap   piece   of   BT-50 

tubing   through   the   large   holes   of   the   two 
end pieces. Inspect the alignment and make 
adjustments  to  ensure that  the  BT-3  tubes 
are parallel to each other and to the scrap 
BT-50, but perpendicular to all of the end 
pieces.

Step 4

   Apply glue to the joints between 

the BT-3 tubes and the large end pieces. Do 
not  glue the BT-50 tube  in place. Do not 

glue the smaller end pieces in place. Set this 
aside for about 20 minutes to dry.

Step 5

    Test-fit   the   pieces   together   and 

make minor adjustments as required for the 
pieces to fit friction-tight, but not so tight 
that   the  pieces   are   damaged,  not   so  loose 
that the pieces fall apart.

Step 6

   Slide the two end pieces onto the 

3”   BT-5CJ   tube,   and   position   them   1/4” 
from each end. Make an adjustment to align 
the slots with each other. Place scrap pieces 
of   1/16”   balsa   strips   into   the   slots   and 
carefully rotate one of the end pieces until 
the strips are parallel to the tube.

Step 7

  Apply thinned glue to the joints of 

the end pieces with the tube. Do not glue 
any of the strips in place. Allow about 20 
minutes for the glue to dry.

Step 8

  Draw a line down the full length of 

all four of the 2” long BT-5BJ fin pod tubes. 
Mark each tube 0.125” from each end. Draw 
a line completely around the tubes at these 
locations. 

Figure 1

Step 9

   Using a large modeler's “T” pin, 

punch a series of holes about 1/32” on either 
side   of   the   long   axis   line,   in   a   zig-zag 
pattern, between the circumferential lines at 
either  end  of   the   tube.   Refer   to   Fig.  1   to 
understand the idea.
