Laid out a line 10mm from the edge of the R/H outboard flaperon tip. Sanded the leading edge of the tip to make it fit better. Decided to add 1 hole on each of the flaperons tips because there was a little gap between the tip and the skin. Used a rivet spacer to match the existing hole spacing. Drilled holes on both L/H and R/H flaperons to 1/8". Deburred the holes and rivet with A4 rivets. One hole on each flaperon still needs to get riveted. I'll need to cut 2 rivets down for those 2 trailing edge holes.
