Ok, guys,, I was different. My leading edge is built up 1/8 balsa. I cut each strip 3/16" narrower than the preceding one. The first layer was glued to the cores and sheeting. Then each layer was 3/16" narrower and glued on to the preceding layer. The ends were 45 degree cut and no joints overlaped anyother joint. I did this until I had the contour I wanted.

Then,,, I used the straight edge sander to feather the edges and round off the leading edge. This edge is important in how the bird stalls. Too pointed and it could have a sharp stall. Mind is blunt and stalls very nicely. But,,,,,,,,,,,,,,,,,,,, I have done NO spins to date, even though the guys still taunt me to do one. Jim
