Biplane Glider

Biplane version of my wing-in-tension concept for small airfoils. Spica airfoils all. Enjoy.

- Cut acetate strips to 130mm (+0/-1) and 79mm (+0/-1) respectively to slip into the wing frames and plane body.
- The front hole is for assembly & weighting.
- Print patterns for the fuselage will affect it's strength and stiffness.
- I recommend printing with a "lines" infill pattern with the model rotated at a 45 degree angle in the plane of the print bed.
- If you mate the centre body together, the fuselage becomes flexible about the yaw axis, this could probably be adapted for RC steering.

Look-Back Review
- I'm really proud of how well the concept of wing-in-tension worked.
- The acetate wings provide a really good surface finish for the airfoil, even if I was using a paperstock weight that was perhaps roo heavy.
- I ended up employing it lots of other places.
- The glider itself...... I really think someone with more small-glider experience could probably "turn this up
