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

Regarding Al Wick's
radiator installation, he broke all the rules.
He just put the darned
radiator in front of the NACA inlet scoop, and has
NO exit plenum. After the
air passes thru the radiator, it just slowly
finds it's way out the rear of
the cowling. Odd thing is that he can do
extended full power climbs without
overheating. Go figure ! I should be
so lucky. Paul Conner
Really? In *front* of the scoop?
