I decided to mount the 4 inch NACA on my 7A to see how it performs and also give others an alternative mounting method. I'm sure it's been done before but it worked out well with little fabrication required. Hopefully it will be ready to fly over the weekend and I can get some numbers to share. My engine engine/oil temps weren't running really hot but I figured since I'm making this stuff I might as well be testing it too. Temps here are high so it will be interesting. If you're interested in any of the carbon componets they're available through bonehead composites.
Interesting concept.
I hope your efforts pay off but that area of the cowling is generally very low pressure and not ideal for a NACA inlet.
I am looking forward to hearing your results and hope you can prove me wrong.
