Dean, in case you have not noticed, Cozy strakes are flat on top. Not much
of an airfoil. I know people with VEZ's that use the same spot for oil
coolers without any aerodynamic problems. Don't wary about it. Jus build and
be happy :)

Al,
I don't know exactly how to phrase this question but I'll take a stab at it.
When you decided to place the heat exchangers in the wings how did you
estimate
the effect(if any) due to impact on the designed airfoil(s)? I think this is a
great place for them in the canard designs. I am thinking about the spaces in
the rear of the strakes for mine.

Al,
Do you have any photos of your oil cooler install showing the
airflow path?

My oil cooler is in the wing root. The intake is on the bottom just behind
the spar, and the exit is out the top further back. It matches a coolant
rad in the other wing.
The first pic show the oil cooler. The second is the inlet "scoop" - not
really a scoop, just an airfoil lip that extends down into the air flow
about 1/2". The third pic shows the rough ducting (early version of exit
fairing) for the coolant rad; the oil cooler is similar, and the fourth pic
shows the exit fairing. The flow through this cooler (and the wing root rad)
is enhanced by the normal pressure difference between the bottom and top of
the wing. At this position of the wing the difference should be higher at
higher angle of attack.
