It shows the automated calculations that produce an aluminium round tube with the exact same (bending) stiffness AND weight as a given round tube made out of carbon laminate.


I understand that If I buy a larger dia with less wall thickness I can reduce waight,

Wouter can you help me figure out what would be the wall thickness for a 100mm dia?

also what alu tube (dia/wall) do you recomend for the boom and spi pole

from the plans the spi pole is 3m, shuld i get longer? 3.5m?

Thanks,
