Buly,
Great to hear that your plane is flying really well. Your temps are very
good. When I read how well yours is running I really start considering
doing away with the turbo charger.
After reading you write up, I went out to the airport today, and flew for a
half hour. My temps aren't as good as yours, but I have a plan to improve
that. Just have been too busy to fly, let alone work on the plane. I'm off
work for a few days this week, but the wife has a whole list of things for
me to do.
What wheel pants did you end up going with ? I still have put any on mine,
but plan on doing so in the next couple of months.
Had an uneventful flight today, but also had my first missed approach.
There was no wind on the ground, but apparently a pretty good cross wind at
pattern. Turned base, realized I was going to overshoot, cranked it on
around, and did kind of an "S" apprach. In chasing the center line, I
realized too late, that I was too high, and too fast. I might have been
able to squeeze it in, but I decided, given the really ugly approach, that
I'd be better to go around. Next time was better, but still struggles to
keep distance from the runway while downwind, and base was abbreviated.

Since it is quiet on the list, I'll report on my Sunday breakfast
flight from Ft Lauderdale Exec. to Okeechobee, which is on the border
of my test area. I was getting tired waiting for the strong winds
that have been blowing for 4 weeks straight, to die down. So this
morning pushed the CZ out and took off with 38 Gal of fuel and 400
lbs on the front seat. The wind was 30 degree to the right at 15 mph
and gusting to 25. I was airborne at about 1200 ft and engine
running at 6-6500 rpm.
There were two items I wanted to check on this flight. I had my new
wheel pants installed, and as expected I gained 10K at cruise.
The other was loud staticky noise in my headsets, that came on only
at high RPM and cruise. After weeks and months of trying everything,
I zeroed on the secondary injectors. They are the only thing that
kicks in at high rpm. Found one crimp connector splice that was done
by my electronics engineer neighbor, totally loose. The metal part
inside was blue from heat (created from the sparking I guess?). So I
had it fixed. The noise is gone and me and my flight captain are happy.
Leveled at 6000 ft and set the plane for cruise. Here are the numbers:
5200 RPM ENGINE
2350 RPM PROP
24" MP
TAS 168-170K
1650 EGT
8 - 8.5 GPH FUEL BURN
WP-4 PSI
WT - 165F
OIL 140F
OIL P. 70PSI
OAT 71F
I was able to bring the mixture down to 7 - 7.5 gph but I can feel
the power go down. I know it is not as impressive as a turbo engine,
but gives me a piece of mind. It runs very clean and smooth and I
don't think like before about boost, mixture, detonation, etc. etc.
On the ground I did not have to even wipe the prop from sooth.
Both landings were in cross winds and it worked out very well
considering my limited piloting skills :)
Bottom line, I like my plane and the rotary. Now I'm itching to
replace it with PP so I can use the third blade on my IVO Magnum . It
is a sickness
I tell you :).
19 hrs and 21 to go before I can fly outside the cage. Now it takes
me 35 minutes to get to the border of my test area and the same back.
