Little gliders

I discovered some advantages of Bienfang tracing paper:

• 30gsm
• smooth both sides
• no need to seal
• ink doesn't spread
• stiff and stable
• has a noticeable grain direction, difficult to tear across grain.

I wonder if Bienfang will buckle when wet and shrink evenly afterwards.

Did a little flying wing, design adopted sweptback, cambered root and straightened tips, and short tip fins for stability (just the tracing paper, without balsa). Structure from 1/16" balsa.

IDEAS:

• Curl Bienfang at the wing tips, then it is stronger in one direction
• double/triple folds for strength instead?
