    I didn't measure the wall thickness of the kit stringers. I will check tomorrow. If they are the same as the Univairs .032, I don't see much difference in volume of material used. Still leaning towards spruce.

    I was just about to start installing the aluminum ones, and I picked up the whole bundle. Got me thinking.........

      Yeah it's a heavy bundle alright.

        .048 wall for the kit stringers. Univair website calls theirs .032.

          FYI - these stringers are extrusions made of 6061. Mark

        That is good information, that would explain the weight saving.

        That is worth considering too, as the 5052 which Bearhawk Aircraft supplies does not need painting and will not corrode. The 6061 can definitely corrode, particularly if it gets wet - think bottom stringers. I believe 5052 is also a softer metal, which means fatigue resistance in the most general terms. They probably use a thinner walled 0.032 because they are using a stiffer metal.
