Use these prints to replace the weak struts on this model.
Note: 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.
Needed to complete
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.
Printing notes
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.
Print with supports and good tolerances.
Assembly
- Cut your struts to an approximate length.
- Test-fit the rods into the Fuselage pieces.
- Glue struts into Fuselage piece using CA (super/krazy glue). WARNING: The CA will bond almost instantly and permanently, work quickly.
- 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.
- Glue the Wing pieces, being sure to get the correct orientation. Again, CA will bond instantly.
I would love to hear from anyone else who prints these and get your feedback.
