Cut the lightening holes and servo lead tubes.

Saved a disappointing 16g per wing, basically 1oz total. As shown in the pic the wings are 112grams (4oz) each.

While cutting the wing tubes I was battling to get the last inch of foam from the end of the tube. There was just not enough friction to 'break' the foam off inside the cutting tube. A drop of foam safe cyano INSIDE the cutting tube. Insert tube and leave for a couple of minutes. A quick twist and pull out the offending foam. Be careful you don't get cyano on the OUTSIDE of the cutting tube.

Next sheeting, capping and trimming. After that, aligning the wings and stabs on the fuz.
