[quote=southstars2012]Correcting some mistakes in my prior post containing the technical details of the R2AK I20 wings. I quoted our wing inner tube sections wrong, and overall weight wrong as a result.
[quote=southstars2012]
- Wing inner tube (inboard seat tube): a bit smaller than outer tube to save on weight, 1.50'' OD, [b]1.25'' ID (0.125'' wall thickness), weight 6.4lbs/10ft, estimated section modulus 0.172 inches^3[/b]...
Total weight: approx [b]58-62[/b] lbs (vs. 58lbs for Hobie 18SX?)
- [b]41lbs[/b] for aluminum tubes (cut to size)...[/quote]<!-- editby --><em>Edited by southstars2012 on Nov 22, 2017 - 10:25 PM.</em><!-- end editby --> [/quote]
