Thanks, Tracy....I should be able to find out in a few
days. Today I removed the ram air scoop and fabricated an intake plenum for the
3 inch scat tubing. As soon as the NACA duct with the 3 inch outlet arrives, I
will install it and be ready for testing. Today I measured the length of the
scat tube that I will need....14 inches. Thanks again for sharing your
experiences. Paul Conner

Hi Paul, the scat tube was 2.75" dia & about 4 ft long.
Gave me a major power loss (compared to ram air) partly due to pressure drop
(1 - 2" Hg) and partly due to temperature rise, about 25 - 30 F. I was
very surprised at both. If you have shorter run it may work
better. The larger diameter would reduce pressure drop but temp rise
would be worse (as a quick guess).

Hi, Tracy....thanks for the heads up....any more info
would be appreciated....was it a long scat tube, and was it 3 inch
diameter? I assume you could not ingest enough air? Thanks for
any more info you can provide. Paul Conner

You have exactly described the first intake scheme I tried on the
Renesis (NACA, Scat tube, etc). Hope it works better for you than it
did for me.
