<DIV><FONT face=Arial size=2>My son did his 5th grade science project
using balsa construction. His project was to determine what bridge
truss design held the most weight for a given span. It was truly
amazing how much weight the structure would hold. The spans he built
where 7"x7"x24" and weighted 1.5 oz, made of 1/4" square med
grade balsa glued together with thin c/a. The Warren truss held 42
lbs before collapsing and the two other structures were close behind
holding 32 to 38 lbs. It was a learning experience for both of
us. It gave me a better understanding of how certain truss structure
builds stiffness, strength and be light weight.

<DIV>Balsa is pretty amazing stuff overall, particularly for a natural
material. The Xylem that makes up much of the superstructure of any wood
(that's what we commonly hear as grain), is essentially a huge
number of tubes arrayed side by side, but interconnected along the
length. The tubes serve a terrific function in the long direction and
the interconnects make the structure have reasonable transverse strength
as well. </DIV>
<DIV> </DIV>
<DIV>The closest thing manmade that will surpass it in terms of
mechanical strength vs flex vs weight vs cost will likely be
Buckytube if you excluded the cost. That's just in laboratories
now, being made in very small quantities supporting very high end
applications. This stuff is the true unobtainium that some have
complained about. But that's another subject. </DIV>
<DIV> </DIV>
<DIV>There used to be an annual competition in colleges where a very
small, known quantity of balsa and glue were used creatively by students
to build some kind of support structure like a small bridge. These
things would hold unbelievable amounts of weight. </DIV>
<DIV> </DIV>
<DIV>Alas, the weakness is shock loading. </DIV>

<DIV><PRE><TT>Not directly applicable to pattern, but certainly a good start:
Buy and build a Stevens Aeromodel kit. The planes are small (35-50"
span, 1-2.5lbs) and electric powered. I'm about 1/2 done building the
Edge 540, and am actually enjoying the build because I am constantly in
awe of the genius wood design and its results (consider that this Edge
540 is 40-sized, but will weigh only 2lbs with more performance than all
but the most dedicated 40-sized 3D glow planes).
