the tube sleeve to locate it before sheeting the core. The core is supported in
the shucks and shimmed as necessary to the proper dihedral angle. The tube is
slightly above center at the root to get the outer end near the center. The
core blank is cut with the root parallel to the centerline so it is easy to cut
the tube hole 90 degrees with a simple guide for height and square ness. See
photo. I hope I reduced the photo enough to fit this post. Contact me directly
for other or larger photos.<o:p></o:p></span></font></span></p>

Brox's web site on balsa skinned wings is very good and does show the
drilling of the servo lead hole with a tube and by hand. <br>
<br>
Their is some great information on these sites on building foam core
wings. But a very important part of a plug in wing would be
the wing tube sleeve hole in the core, to be straight and parallel to the
desired line centered and at the right angle to set the dihedral. Is there a
site that explains or shows the process of set up and drilling of this
hole? If this step is not perfect looks to me like the wing is dead no matter
how good the skinning process is.</span></font><font color=black><span
