I've
been thinking about building an extraction duct (next
winter) for my RV10. My exit area is overly large and I'm sure
I have excessive cooling drag. The lower fairing ends 5" below and 1" behind the
firewall. The extraction duct would join the existing lower fairing. This is an
old picture and my muffler is already hanging under the belly. The grid lines in
the excel attachment are at 1".
