Hello,
I have been working on the CAD Conversion of the Carl Goldberg Extra 300 - 68" wing span. I only have sheet one of the plans. Still looking for sheet two (wing and stab) to be able to finish it up. I took a guess at the stab based on what is on the sheet one. Take a look let me know what you think. I'll get a full size PDF posted once they're complete.
If anyone has a scan of sheet 2 that they can send me, I would greatly appreciate it.
The instruction manual is available here: http://www.greatplanes.com/manuals/discontinued.php
