<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,
