<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>I have planes 15 years old with 6" tube (since 1992
European Championship). The load should be distributed equally along the
tube not just at the root and at the end of the tube !!! I transfer the
load to the top and bottom sheets with Balsa spar and reinforce the sheets
locally with 2 OZ carbon that's all !</FONT></DIV>
<DIV><FONT face=Arial size=2>Saving weight can lead to loss of aircraft but
adding weight will too. If the plane is too heavy it is worthless and diet
program for pattern plane are very expensive</FONT></DIV>

<DIV><FONT face=Arial size=2>Wow! that's really short. I guess you
must be using some kind of spar arrangement to spread the load at the end of
the tube? I am stuck with the 3/4" wide carbon fiber cloth spars on
top and bottom in front of and behind the wing tube because this
experimental wing has already been sheeted. I could start from scratch
but that would make this experiment too time consuming and its already
interrupting the building of my Symphony.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've now gotten recommendations at both ends of
the spectrum so I've decided to compromise and trim a bit from both
ends. This leaves the tube at 9" into each wing, which still seems
pretty safe. Especially considering Mike that only uses 6".
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Man, if 6" is all you need, then we could all
be saving some weight here.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>Theoretically you need 3 times the diameter
to transfer the moment. I go 6D into the wing (about 15 cm) and never had
any problems</FONT></DIV>
