Doing a little work inside the fuselage interior. Needed to finish off the side walls. Looked at a couple different options;
1. Laminating .015 styrene on 1/16" balsa
2. Fiberglass lay ups of various thicknesses
3. Laminating fiberglass on 1/16 balsa
After several tests ended up with 1/2 and 1 1/2 ounce glass cloth wetted out and the excess squeegeed off, then vacuum bagging 1/16" balsa sheet to the back. Selected the lightest 1/16" sheets from a stack purchased from National balsa, these sheets weighted 12 - 13 grams, this works out to 7 pound balsa. The sheets ranged from 12 to 22 grams each, 7 to 12 pound balsa. After doing the calculations I found it interesting that there are exactly 256 3"x36"x1/16" sheets in a cubic foot!
Next move will be the shelf for the rear seats. Since this need to be a little stiffer 4 ounce cloth was laminated to the back side of same sheets used for the sides.
