Rob,

Cross section at the point of cut would be about 3/4 x 1/2.=A0 Main gear fin= al link is much thicker.

I think the forces are greater on the nose.=A0 Empty W&B shows about 390= on each main gear leg straight up and down (side tension/compression loads=20= on main links in x-wind landing and taxi turns),=A0 whilst 425 sits on the n= ose gear which is at about 12* (I think?) rake, thus applying some "pull apa= rt force" on the link.=A0 Also, upon gear retraction, the nose is the last t= o come up because of gas spring pressure adding to the pull required.=A0 Dur= ing flight, main links hold up their weight, nose holds up its weight on a l= onger arm plus force of gas spring.=A0 Am I overy cautious?
