Geez.....I did say in front of the NACA duct, didn't
I?   Obvious correction.....It is behind the NACA
duct. 7 inches behind it to be exact. Thanks for the
correction.  Also thanks to Ed for his detailed
explanation, and also to Perry Mick. Since he has
had a ride in Al Wick's canard, his info was very
interesting. I guess if I were to just take off and
climb out at half throttle, I might be OK.  (Yeah,
right)....I'm obviously going to have to increase
the size of my planned radiator.  Wishful thinking
had me hoping to size the radiator similar to Al
Wick's so it could go directly behind the NACA duct
and eliminate a whole bunch of plenum work.  I guess
there is no free ride.  I now am considering just
placing the oil cooler there, (it would fit nicely),
and use the two upper factory cowling scoops for a
pair of airconditioning evaporators, one on each
side. The nice part about using a radiator would
have been the ability to have a Spal fan
thermostatically controlled.  Thanks again, Ed,
Perry, John, David, etc. for saving me a lot of
money and wasted time trying to make a radiator with
insufficient surface area cool my rotary. Back to
the drawing board.  It's cheaper to do it over again
on paper than on the aircraft.   Paul Conner
