Hi! Duncan.
Thanks for that message. I spoke to Andy Draper today and he said that
the gills initially were put in for cooling when parking up, and had
been surprised when flying without doors once he put his hand over the
port gills and found hot air! This rather substantiates my not having
the gills as a Jabiru Cowl.
The Jabiru Carb sits right above the muffler and I had a suitably
placed soldering mat on top of the muffler , can't see why this
shouldn't work for Rotax and leave the gills blocked
Regards
Bob Harrison.

Probably not much, other than to create a disproportionately large
amount of drag. There must be a huge plume of air coming out of these
gills that destroys the airflow down the sides of the fuselage.
I had a nice photo of an oil streak on Williams Europa, showing flow
reversal just aft of the gills. Conversion of the gills to a rear-facing
exit may prove beneficial (to reducing cooling drag), although care
needed to ensure fuselage composite not overheated. I have the moulds
for such a mod., but never tried it out.
The detailing on Daryl Greenermeyer's Reno Legacy shows the way to go.

What purpose do the Europa "Gills" serve?
