REFLECTOR: Overhead NACAs

[Jerry Teitsma via Reflector]

You certainly need some ability to handle engine movement.  I used a section of rubber (cut from an inner tube) in the connection.  The gap between the rigid sections is about 2 inches.

For those with the overhead NACA vents for engine cooling, does the duct 
connect directly to the plenum or is there a flexible joint for vibration? 

Thanks,
