Right, and this is why aircraft never use aluminum parts, particularly not in crucial areas like the airframe, wings or landing gear. It always warms the cockles of my heart to see an all-steel 50-year-old B-52 cruising over to Fairchild AFB. Imagine if THOSE were made of aluminum. oh wait.

Hey Axiom, if it's of interest, I sneaked into the LBS and weighed a 17.5" 7.2FX, 2012 model. It's 26.4 pounds. If you ride a taller one, figure somewhere in the 27-pound area.
