<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>

<DIV><FONT face=Arial size=2>Lance, I usually go 12" but have seen many
shorter. </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>
