No,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
Ed.

Great to hear about
the performance! Wow! 3000 fpm and UP at that{:>). Sounds
like you are getting the little bird debugged just great.

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)
