     Good point. Might be needed in a pusher. On the other hand at climb out
     angle of attack it might be fine as is. I am going to try it on
     the KIS without as the boundary layer does not have much of a chance
     to build up.

     On a pusher you could use a flat plate on top and space it down 2 inches.
     That should handle the boundary layer.

     Another plus for this arrangement for the pushers is what happens 
to CG. I was previously running 30lb of ballast in
     the nose with the Lyc O320. I would like to eliminate as much of that as possible.

     I have two concerns relating to the pusher configuration. 
One is the potential for damage from FOD kicked up by the
     nosewheel. The other is cooling during taxi. I don't see any 
way of using an augmentor or fan for low speed
     assistance. Since hot air rises it will take some encouragement 
to get the air to go down through the rad. Does
     anyone know if an idling prop has enough suction to affect it from that far away?

     Dick Gregory

I don't think so Dick. I think you will need a fan either blowing down
from the top or sucking through from the bottom. Or use a water spray
on the rad like Tracy uses. 

Hardware cloth can  take care of the rocks.
