LSaupe,
My understanding is that the lighter wing of the 1030 has less drag braces per wing than the 1100. The 1030 has 3 per wing, the 1100 has 4 per wing. Also, on the 1030, the first of the three drag struts, i.e. the one nearest the root, is made of 3/4" X 3/4". The second one is made of 5/8" X 3/4", and the outermost one is made of 1/2" X 3/4". Whereas on the 1100, the first and second of the four drag struts are made of 3/4" X 3/4" and the third and fourth are made of 5/8" X 3/4".
I was also told the rear spar on the 1030 is weaker than that on the 1100. The front and rear spars for both models are made from the same stuff at the same dimensions. However, on the 1030, the doubler that runs along under the upper spar cap at the rear strut attachment is made of 1/2" X 3/4", whereas on the 1100 it's made of 5/8" X 3/4". |
