Chuck,
Read your note having to do with cycles of the big planes having to do with pressure expansion, contraction etc. Can you translate that to a 150? Obviously, pressure expansion is not a factor. I would think cycles of take offs and landings and flexing of the landing gear would be the major area along with flexing of the wing spars in flight. is this correct or are there other places where flexing would be a factor, ie. rudder, stabilizer, motor mount?
