Durability is an interesting tradeoff. I once complained to the designer of the Little Nipper/Seeker/Swyft about things being fragile and not surviving my "landings".
His response has served me well. Everything needs to be strong enough without being too heavy. And besides, eventually you stop crashing. My goal is 100% hand catch and that takes a lot of wear and tear off the airframe. I'll come back early rather than stay our there too long. Less walking that way too!
FWIW - I've never broken a CF push rod in a crash. I've found that their flexibility has even saved a rudder or two when I've missed a pop-up hand catch and dropped the poor thing on its tail.
There are lots of options and everyone has their own experience with them.
Alan - I'll try to make some progress this weekend on the tail group and post some photos for you.
