We may have a minor rad breakthrough here. I am talking to Ron Davis
about building some rads for us. He does not know they are for aircraft
yet so don't tell him. He does know they are for rotaries.

We had good communication because  of my racing experience. He was a fan
of Chaparral as a kid back in the 60's :-)
What I will be asking for is 16 inches wide about 20 inches long
cross counter flow rad two pass rad. As per this sketch. Any comments?
any other request. I can get the price down if he feels he can sell more.

Maybe hard points for mounting?

Good point Bulent. Anybody have any suggestions or preferences?
I would think sheet metal flanges along side the tubes would be useful for
drilling mounting and composite duct attachment holes. Little cylindrical stud rubber 
isolators from Barry might be nice for vibration isolation mounting. These are 
sold by MacMaster Carr at low cost. The A10-041 #8 size (8-32 studs) will carry 
seven pounds each in shear and 14 pounds each in compression. These are a 1/2 
inch thick and 3/8 inch inch diameter. See the ACRE NL web site for Barry's URL.
