Completed all alum wing

Post by mmcgrew »

As most know. I built all aluminum wings (spar, ribs, leading edge). Here is the finished product. Finished wing weighs in at 60 pounds. I am curious as to how this compares to the wood wing?

Hey Michael,

That wing looks really nice, beautiful scallops! We understand it is a lower wing (bracket can just be seen). Does this weight include the aileron and control tube as well? Will note our wings weight when completed.

Lovely wing! I would like to see what your structure looks like. Do you have any uncovered pictures, plans, etc? I am still deciding which way to go...wood or aluminum. Decisions, decisions...

Thank you kindly. I am impressed by all the work. I am curious about this one photo though. In picture three you show a lower wing fitting and was wondering if the shim block is held to the spar by anything other than the three fitting through bolts?

Thanks again,

Michel.

P.S.: Those wing bows must have been a %$#^$ to bend precisely.
