Hi Brian
I'd be interested in seeing some engineering figures on tail plane hinge
forces versus bracket strength spread across say five hinges to RR design
just out of curiosity. Out of my league I'm afraid.
However, I agree that for the cost of a few cents it's not really an issue
to go with the highest strength possible unless there is a fatigue or
corrosion question in the longer term. As I said, I did use 6061 for my
control brackets but simply wondered if it were really necessary.
