Getting ready for the wings. They have you glue the top and bottom spars prior to fitting the shear webs. I think I will dry fit the bottom spar and measure/cut all the webs first; this will make measuring much easier. After they have been cut, I will glue the spar ensuring final rib alignment then a quick sand to tight fit the webs.

With the planned increase in the aileron, I will cut end piece of R4 prior to assembly.

Question: Step 9 says "Make marks on the ribs 3/8" forward of the rear spar". Where do I measure from? The fore or aft side of the spar (i.e does this include the width of the spar or do you measure starting from the edge of the spar?

Question: Is G1 supposed to be 90 deg? Mine looks like about 85-87 deg and I would rather use a square to set at 90 if this is the correct angle. I am not sure the die-cut piece is going to be that accurate but I know a square is.
