Subject: cooling suggestions?

Hi, Paul....I need to address my cooling system at this time. I am building an SQ2000 canard pusher.  The aircraft in it's
original configuration has two armpit scoops just above the wings for downdraft cooling, and one large NACA scoop underneath. I
have loads of room on both sides of the engine, and a fair amount of room under the engine.  If you have the time, might you
look at the following pictures and possibly suggest the best method of attack regarding cooling?  I can place a large radiator
on each side of the engine, or two evaporative coolers just behind the armpit scoops, with the oil cooler underneath, or I could
put a radiator under the engine, or ???  Enclosed are pictures with just the bottom cowling in it's approximate position to show
the available room around and under the engine, as well as two pictures of the factory cowling (with a Lycosaurus), which shows
the position and sizing of the armpit scoops.  Any suggestions will be greatly appreciated.  Thanks for taking the time to
assist.  Paul Conner

Not likely to work very well. They are in a a low pressure area and there is no boundry layer
bleed. Best to go with a P51 scoop and place the rad under the engine.

BTW send that motor mount back to the guy that made it. Very likely your
engine will drop off in a hard landing or high G turn,

Also BTW I am back from OSH.
