I guess that's inherent to trusses in that all members are under tension or compression and no radial loads.
only problem with the pultruded rods is the diameter. the max dia available is 16mm with a 2mm wall.
correct me if I'm wrong, but I think even a 1.5mm wall but 20mm diam would be better than the 16mm as wider pipes tend to be more stiff.
I've got a sample 16mm, so will test.
I wonder why most professional scopes like planewave, officina stellare and other RC's use woven tubes.
I've seen some ATM builds with roll wrapped tubes that are actually bad at axial loads.
