One thing I did notice on this flight. Taking
my feet off the rudder pedals and placing them flat on the floor changes the
vibration characteristics of the floorboards and affects the operation of the
ANR circuit in the headset. In general I norice the ANR is much more susceptible
to being confused in the RV with the higher freq noise environment.
Previously the only time I'd ever experieinced
problems with the ANR was in my buddy's Mooney during takeoff. At full power the
ANR would cease functioning until the landing gear came up - then it would
return to normal. In the RV different power settings, even turning my head at
certain angles, confuses it. I dont recall the Zulu doing this. Probably a more
sophisticated ANR circuit in the Zulu.

Good report Mike. I know what you mean about a quieter
muffler. My ANR headset does a good job of killing the low frequencies,
but a poor job on the higher frequencies. The rotary has
both. So take your pick, turn the ANR on and listen
to the high frequencies, or turn it off and listen to the low
rumble. If I could only find an ANR that can do both I would be a happy
camper.

I added another 1.3 hours to my total flight
time today. And for the first time I landed and was completely satisfied
with the flight. I'd still like to quiet it down a little, but this was the
first flight where I didnt feel like there was anything that had to be fixed
before the next flight. Even the landing was pretty decent.
I've got just over 9 hours of flight time
and about 40 hours of engine run time now. So far all of my flight time
has been directly over the airport because to venture away requires flying
over about 50 miles of mostly unlandable mountainous terrain. But I'm
starting to think seriously about stretching the legs a
little...
