Could someone please help me read these plans. You can get to the plans by following the link below.

1. What thickness balsa should I use for the wing ribs (trainer config-page 3).
2. What thickness balsa should I use for the elevator.

The plans are in DWG format. Clicking to the link below will download the file ZIP.

If you don't have a program to read CAD files there are many free readers on the internet, just go to google and type "free DWG file viewer".

Thanks
