Quest X-30 Aerospace Plane Part 5, Fin Prep

The curved front of the inlet fins were sanded with some 220 grit wrapped around an old engine casing.

I cut off the uneven front tips off the inlet fins. I probably should have left them long. But, the overlay sheet showed them with a squared off tip.
After sanding them square that front tip was too thin and not the same between fins.
Later I found out they weren't long enough to cover the white location area on the aeroshroud body.

TIP: These die-cut fins were chipping off the back root edge corner.
Sometimes you can place a drop of CA on this corner to keep the balsa in place. It'll sand off easily after the glue dries.
