<DIV><FONT face=Arial size=2>Where ever the tube ends is a high stress point.
Getting it further out on the span reduces the loads imposed at the tube ends.

<DIV><FONT face=Arial size=2>If you can get away with it, tube reduction also
saves weight.</FONT></DIV>

lengths</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Here's a question for anyone that's built a few
planes from different manufacturers. How much wing tube is the optimum
to have sticking into each wing? </FONT></DIV>
<DIV><FONT face=Arial size=2> We cut our wings for 9.75" of tube
in each wing but that's only because that's the length so that the false rib
can support the gear plate. What if the tube only went into the wing
8"....is that enough to stabilize it?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm thinking of another (of my many) experiments
by clipping the wings of an Aries by removing the root. The wings I have
already have a wing tube mounted so I'd be shortening the amount of wing tube
that goes into the wing.</FONT></DIV>
