Re: New Scoop
Ed,
Mark,
I have a
cowl flap. At first it seemed to do no good at all, but after about 5
hrs of flying around on a 90deg day testing it open and closed, it does seem
to make about a 10-15 deg F difference (coolant) and cost me about 5 kts
in cruise speed. It takes a long time for the change to manifest itself
in my temperatures. Luckily I only seem to need it in climb even on a
hot day. Looking back, it was worth the trouble.

Re: New Scoop
Mark,
I considered them in
my early days when I was fighting high temps. But, once I solved that I
have not really considered them. The only person I am aware of using
them is Bill Eslick. You should contact him for details, but my
impression was that while they appear to work in aiding cooling, they also
acted like a speed brake dropping over 10MPH from his cruise. I believe
he also found it very difficult to close them down against the air flow out of
the cowl when he tried to close them to minimize drag.
But, again contact
Bill for the full skinny.
