Fully 3D printed modular RC Sailplane.

**** Two files updated 18 May 2013 ****
The two files are the Vert_stab and Fuselage_tail files. A very minor change was made to the vertical stabilizer by removing some material at the bottom of the control linkage channel. I've added a feature in the fuselage tail part to allow trapping the sheath end of the flexible control cables using two set-screws. This prevents having to cement the sheath in place to prevent movement.

I don't quite understand what you are saying, but I can only assure you that the wing panels are very robust and fully covered when printed properly as designed. The photos of the plane that I've included were printed from the very files that you are able to download. Check out the Made section as others have posted their results.
You mean your prints also only bond the internals together, without a single extrusion on the whole airfoil perimeter? I think for this to be actually flyable that would be kinda necessary.
Thank you :)

The wing requires two 1/8" round carbon fiber rods, and one 0.196" square carbon fiber rod for each half. The rod insertion holes will have to be cleaned out with a drill in some cases. To ease sliding the wing panels onto the rods use dry bar soap rubbed onto the rods first. I used a mitre box and hobby saw to cut the brim from the end of the wing panels. The entire assembled wing weighs 12.7 ounces.
