REFLECTOR: Roof NACA's

[Carruth, Joel L]

For what it's worth... the instructions include construction &
installation.

Quoting step #1:
"Mark a centerline on top fuselage from cowling cut line forward 25".
Mark 2 more lines, one on each side, that start 10 3/4" from center line
at the rear to 11" at the front. This would be 8 3/4" to 9" on the
smaller fuselage/engine. This gives you a little toe out on your two new
centerlines..."

The instructions cover the rest of the installation in great detail.

Maybe I wasn't clear about this.

I didn't ask how to build the NACA's, I have them, I asked how far apart
they should be..
