<DIV><FONT face=Arial size=2>Paul,</FONT></DIV>
<DIV><FONT face=Arial size=2>This is a good idea. We sell the scoops but
I can vouch for the nasa duct idea. It is on the plane I flew at
Nats. There's a picture on our website (<A
href="http://www.aeroslave.com">www.aeroslave.com</A>). Go to the
Symphony page and scroll to the bottom. Also take a look at the chrome
rendering picture. On this you can see how the nose of the fuse curves
so that a hole cut in the right spot is actually going to gobble some air from
the oncoming freestream. One thing I like about the nasa duct is it
gives me a finger hold for my pointer finger because the Symphony fuse front
is so wide you can't really grab it well. Also, I put a black CF reverse
scoop under the duct hole so you can't look in and see the crankcase.
Remember the incoming wind doesn't need to blow on the crankcase. It
will blow around the engine and be drawn into the faster moving air moving
over the head. This draws the heat from the whole crankcase
area.</FONT></DIV>

<DIV>There are a few options... If you don't like the looks of having
a scoop on top of the fuselage nose, you can use a nasa duct. All you
will see</DIV>
<DIV>is a somewhat teardrop shaped hole in the fuse.... The other
way is to place a scoop on top. Aeroslave has scoops you can order, or
make one</DIV>
<DIV>yourself and bond it on. I like the nasa duct because you can
simply grind the duct hole in the fuse and reseal the raw edges
without making</DIV>
<DIV>a mess of the paint job. The air directing scoop is bonded on the
inside of the plane and directs air onto the crankcase. I
don’t have any</DIV>
<DIV>pics of the ones I've used. Maybe someone out there can
help. If not, I could sketch it out for you.... It's pretty
simple to do, and doesn't take </DIV>
<DIV>much time.</DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [NSRCA-discussion] Engine
cooling</DIV>
<DIV><BR></DIV>Hello all,<BR><BR>Well after about 20 flights or so I
finally solved my engine problem. The engine was getting hot but
only the crankcase half of the engine. The head had good cooling but
air could not get to or away from the crank case. The problem is I
now fly 5-6 flights one after the other with no down time between
flights. Last time I flew the plane the field was always packed so I
would fly a flight and not fly again for a half hour or so, so the engine
had a chance to cool down even though there was little to no airflow to
the bottom half of the engine.<BR><BR>The question of the day is...How are
people putting scoops on the top of the engine compartment to get cooling
air in to the crankcase? I have a makeshift scoop made from the
plastic lackaging from a hotwheels car but need to make and install a
permanent scoop. The plane is really ugly with the makeshift scoop
but I have flown it and it proved to keep the engine cooler and the engine
seems to be getting better with every flight as opposed to worse like it
was. <BR><BR>Thanks in advance for the help. My guess is I
will need to fabricate something as I am leaving for a contest on the
21st. It will be my first contest in about 10 years and I cannot
wait.<BR><BR>Paul LaChance<BR>Va Beach,
