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'd rather not upload all the required files if you only needed to modify certain ones. Reply with a short list, and I'll add those as a start. The one advantage of the short wing sections is the ease of repair. It's also easier to clear the holes for the CF rods.

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.
