Just about finished installing the nose cone. One thing I would do different if I used a coping hand saw to cut the cut outs (carpenters tool) and it worked perfect. Very fine cut good control and fast cut, what could be better. The instructions have you cut the inside line and sand the remainder of the line off for control of not cutting too large of a hole. The problem (if you call it a problem, I do) is after you are finished and then use the cutouts for the filler piece behind the prop. blade, the extra you sanded off ( thickness of wide marker line) is the width of the gap you have between the cone and the filler piece. Had I carefully cut with the coping saw the outboard side of the line I would have had less than a 1/16" gap. I now have about a 1/8" gap that I added glass to tonight to close the gap on both sides.
This is only my opinion take care cutting yours.
