Thanks Doug. I have to improve my ground cooling now. It is because
of the pusher design, not the cooling system. I land with 170F WT. By
the time I taxi downwind to the hangar,temps are 210F. Even this
morning at 6AM while walking the dogs, I was thinking how to improve
the ground cooling?
It's a sickness I tell ya! :)

If this is the current configurations you need another of these
large round tubes on the left side that are cut off straight
just in front of the prop. Then add 45 degree root cuffs to the IVO
prop to suck the air through the rads. That is what I would do.

I thought about it Paul, but it don't have the guts to start on it :).
Also the prop has the electric hub and I have to make separate cuffs
for each blade.

True but the inner ends of the blades hardly twist at all.
I don't thing you will ever get enough power out of 12 volt
fans to do the job but it is worth a try. I could be way wrong
on this.

If your only problem is ground cooling, could you set up some sort of
watering system to spray water mist on the radiator while you taxi?  I don't
know how effective the evaporative cooling would be, it's just a thought.

It is very effective. Tracy Crook and others have used the idea.
