My ducts are on the inside of the cowl inlet and
yes there is a lip formed by the foam weather stripping which I would rather not
have. On my Latest ducts (yet to fly) I have eliminated the foam, so we
will see if that works. But, with the foam strip I have flown over 225
hours with plenty of cooling. So while I do agree they undoubtedly
distrube the airflow, apparently not enough to interfere in any serious way with
my cooling.

Sorry Ed, the last
time I looked at your ducts there was a big donut in the
opening..:0). Is there a turbulence causing lip with the duct,
foam separator and the cowl? Does the duct fit around the outside of
cowl inlet?

Re: Doin' the duct
Tommy, I basically bring my ducts
out to the inlet opening and use a bit of 1/8" thick foam weather-strip
insulation to prevent contact between duct and inlet part of cowling.
There is very little vibration to content with unlike a Lycoming which would
play havoc with such a set up.

[FlyRotary] Doin' the duct
Hi Guys.
I need
understanding on how to mate the radiator ducts with the cowl opening.
I can see how to mount the rads to motor mount and redrive back plate.
Follow on in the footsteps of master glass scuptors like Tracy. Ed and RD
with foam, electrical tape and poprivets.
But I can’t ‘see’
the junction of duct and cowl.. Thanks for any ideas. The duct
tape is a little cheezie..:-)
Regards,
Tommy
