Descripción
Purpose: These components are designed to replace the plastic wing struts on the FMS PA-18 1300mm Super Cub with carbon fibre rods. The author notes the design is not perfect, as the front strut is swept forwards slightly, causing a small bend in the strut.
Practical Uses: Replacing weak plastic struts with carbon fibre to improve the model's structure.
Included Parts
- Fuselage 4mm.stl
- Wing 4mm.stl
- Fuselage 3mm.stl
- Wing 3mm.stl
Printing/Assembly Guidance:
Printing: Use a material with good layer adhesion such as Nylon (the author used Taulman PCTPE), ABS, or ASA. Do not use PLA. Print with supports and good tolerances.
Assembly
1. Cut carbon fibre rods (4mm or 3mm, at least 350mm each) to an approximate length.
2. Test-fit the rods into the fuselage pieces.
3. Glue struts into the fuselage piece using CA (super/krazy glue). Warning: CA bonds almost instantly and permanently.
4. Install the fuselage piece and trim the struts to the correct length. Use the wing pieces to verify the length, which is approximately 330-345mm.
5. Glue the wing pieces, ensuring correct orientation. Note that CA will bond instantly.

<p>Use these prints to replace the weak struts on this model.</p><p><strong>Note:</strong> This design is not perfect, but it works. I did not realise that the front strut is swept forwards slightly, so there is a very small bend in the strut. This has not been a problem in practice.</p><h3>Needed to complete</h3><p>You will need 4x carbon fibre rods, 4mm or 3mm, at least 350mm each. I used CF tubes which were a problem to work with due to their susceptibility to crushing. I would recommend 3mm rods but I have not tested these.</p><h3>Printing notes</h3><p>I strongly recommend printing in something with good layer adhesion such as Nylon. I used Taulman PCTPE, a Nylon blend which is printable on basic printers. ABS or ASA would also make good choices. Do not use PLA.</p><p>Print with supports and good tolerances.</p><h3>Assembly</h3><ol><li>Cut your struts to an approximate length.</li><li>Test-fit the rods into the Fuselage pieces.</li><li>Glue struts into Fuselage piece using CA (super/krazy glue). <strong>WARNING: </strong>The CA will bond almost instantly and permanently, work quickly.</li><li>Install the fuselage piece and trim down the struts until they are the correct length. Use the Wing pieces to verify the length. They will be approximately 330-345mm.</li><li>Glue the Wing pieces, being sure to get the correct orientation.
