Hi Bill,

A few cooling suggestions

Bring the duct further out so it is the first
thing the air see's.  It does not need to
be attached to the cowl.

Put a radius on it even if you have to cut the
existing radius on the cowl to fit it in.

Cut away the adapter plate for cooling air exit.
It is way over kill for what it does and it is partially
blocking the back side of the rad.

By the way, after SEVERAL   issues, I have now flown off the 40 hours on my
KIS. I am on travel again, so further flight testing will be in April and
May. The biggest setback was the death of my Blue Mountain EFIS, at the same
time that BMA went belly up. Took me months to get a new system (Grand
Rapids) installed.  Then some issues with SAG and a Pitot Static leak.

Flying good now, probably marginal cooling in hot weather, have to see if
the cowl flap I installed helps.
