Engine Cooling NACAs

I have an older Velocity body - before downdraft cooling was implemented therefore the installation is different than current models.

Positioning the pre-made down draft cooling NACAs

Right NACA cutout and beveling of the foam at the forward portion of the NACA.  Note the line on the body from the outline of the NACA.

I cut back the outer glass and removed it to allow the NACA to sit flush with the body.

Right NACA in place.

I predrilled holes and used drywall screws to hold the NACA in place while bonding it to the body.

Left NACA cutout.  

Left NACA put in place and outline drawn on the body.

Right NACA glassed in place.
Fitting Left NACA.
Glassing Right NACA (recommended by Scott with this older body style.)
Left NACA glassed into the body.
NACAs filled and sanded.  Also small NACA being fitted.  Small NACA provides fresh air for the internal air plenum.
