Plenty of commerce in USA , so why cant i spend
some bucks and get some aluminum shipped ?
I've got many practical designs for airplane .
i'll probably go for a single 75" four blade prop and
3 wings , that fold fwd . Frame cant be riveted aluminum
for the stress points . such as landing gear . too much
weight , to spread out into an alum frame .
brazed bicycle method can take a 10,000 jolt on
landing . Alum cant .
cycling steel back and forth , but less than 44,000 psi
it will never fail . Alum will fail , at any small lload .
That stress maybe 122 million cycles , but it will fail .
Steel wont . Even 87,000 psi UTS tubing , cycled at
30,000 psi , will NEVER fail . Alum will !
Old steel framed bicycles were lighter and stronger
than todays alum frames .
Longevity-inc is on the skids , they pay the companies
owners $4000 net , a year .
their welders dont weld .
