Ed,
I can syphathise with you. I didn't make it this year
either. I was supose to fly down with another builder
on Saturday, but no luck. The weather in SC has been
the same crap that you have had. Some good news today. I flew the Cozy this morning
(finally), and got a look at the temperatures with the
new scoops. I need to add a couple of bolts to hold
the oil plenum to the cowling, but even with it
blowing by allot of air, the temperatures were better
than they had ever been. The bad news is that my oil
leak is back on the redrive. It had stopped for a
while, and I had attributed it to restriction in the
drain line, but today it started leaking again. Looks
like I'm going to have to replace it.

MessageNo,Rusty, the #$%^@ weather continued to
keep the ceiling low until about 2 hour after my
deadline to a launch. THEN it began to clear up.
Low ceilings without letup for two weeks and it
couldn't clear two hours early. Really regret not making it, but just not up to a 16
hour drive ( I must admit I have gotten very spoiled
by being able to fly everywhere). Grandson's
birthday was Saturday so he was very pleased that
grandad attended his party rather than off flying
{:>).
Got to start on redesign of my exhaust/muffler
system. From the theory (If I understand it) It
appears that the reactive (sound canceling) type
muffler is the approach with the most promise. It
tends to reduce low freq noise (which is the
predominate energy) in the rotary's exhaust. The
absorption type muffler appears to be best for
frequencies above 1000HZ. So perhaps a combination.
In any case, I intend to get the noise level down to
a more acceptable level before next Years flyins.
Appreciate you continuing to share your performance
data. While nothing comparable to you performance,
my overweight RV-6A has also responded very nicely
to the 2.85 and larger prop and the good news is
that my fuel burn and airspeed appear to be very
comparable to the 2.17 combination. Rpm is slightly
higher (approx 200-300 rpm) for the same 2.17 fuel
burn rate - I presume due to a slight lesser load of
the gearbox/prop combination at cruise. Initial ROC
has increased by approx 600 fpm.
Still need to get some more definitive data on
performance. So will probably start that in a
couple of weeks.
Best Regards

(unofficially)
Great to hear about the performance! Wow! 3000
fpm and UP at that{:>). Sounds like you are getting
the little bird debugged just great.
Ed Anderson Thanks Ed. It's finally starting to be fun. BTW, did you make it to Lake City?
Cheers,
Rusty (still happy to be rid of the turbo)
