Great Ideas From Phoenix Owners

 This one is absolutely the best one.  Jeff Shingleton reported that he saw significant performance gains from the addition of top surface gap seal to the elevator.  As you probably know, air below airfoils in high pressure areas tries to sneak around the ends (vortex) or up through gaps, to get to the lower pressure area.  So I ordered some 35mm x 33m mylar gap seal tape from Wings and Wheels.  To hold it to the surface, transfer tape is used, 16mm x 33m.  And then to make sure it does not come loose, 25mm PVC tape is used along the leading edge of the mylar.  There are also application instructions on the W&W website.
Ok, so what are the performance changes?  To find out, I took my clean and polished plane up for some pre-gap seal numbers.  Minimal stuff in the baggage area, 5 gallons of fuel total and 190lb me flying solo:  At 0 degree flap, stall buffet is 42kts, stall is 40kts.  With 10 degrees of flap, buffet is at 41kts and stall is 38kts.
After the gap seal was applied the next day, I flew again.  0 degrees flap, buffet is 40kts, stall is 39kts.  At 10 degrees flap, buffet is 39kts and stall is 36kts.  So a 2kt improvement after the gap seal!  I was able to thermal at a constant 40kts without buffet, using 10 degrees of flap.  I'm telling you, it was almost like flying a different glider!  Just amazing.  Thanks Jeff!!!
I will also apply the gap seals to the undersurface of the elevator and both sides of the rudder for drag reduction.  I also bought some 60 degree zig-zag turbulator tape and will apply it to the wing undersurface once I figure out where to put it.

Next up, O rings on the pitot tube.  The Boulder Phoenix Syndicate had very low airspeed readings on both Dynon and mechanical ASI's.  They found a missing O ring (the 3mm ring) and the others were cracked.  They have replaced all of the O rings and everything is good now.  Their probe had been stored on the front panel in the sun so maybe the O rings dried out and rotted earlier than usual.  I keep my probe on the back shelf and apply Carmex regularly.  The photo above is my probe and O rings and they all checked out good.  O rings can be obtained from theoringstore.com  They are Buna-N 70 O rings, 1mm x 3mm, 1mm x 6mm, and 1mm x 8mm and cost 14, 16, and 18 cents apiece.  The Boulder boys plan to replace the rings yearly.  
Oh yes, Eric Greenwell came up with the great idea of wrapping the black probe with yellow tape to make it more visible.  We do that to all of the new planes now.


 The O Ring Store also sells this lube specifically for the O rings, so I bought a tube and will use that from now on instead of the Carmex.


 Another pilot who will remain nameless took off one to many times without the probe installed.  I admit I have done this as well.  (If this happens to you, will you immediately think to use the GPS speed to get back on the ground?).  So his idea is to hang the keys from the probe plug.  Great idea, so I am doing this now too.  Also, the bungee loop on my keys is to hang the keys on the prop feather lever when the prop is feathered so I don't try to start the engine with the prop feathered.  (Someone broke their prop doing this!).
Keep those great tips coming, folks!

More on the Washington Fire Quilt Airlift

Jan's new Gel Cushion puts her higher,
where the seeing is better. Feels nice,
too.

 Miserable visibility going up, as the
smoke from 5 major fires darkens the
skies. It smelled very smoky at times.

 We remove the quilts at Anderson
Field near Brewster, WA.

 Ready to return to Richland. It's looks clear from the
ground, but only 3000' aloft, the smoke is so dense,
we decided against any sightseeing near the burned
areas.

 On the way back to Richland, we stopped at
the tiny town of Mansfield for some coffee
and buns at the Town Bar. It's a rare
situation: The airport is right on the edge of
town, and it's only 600' from the tie-down to
the bar!

You walk through the park to the bar, so the
"pilot's lounge" is only 300' from the ramp.

Quilts by Air

Here's how FedEx gets packages from remote areas

It's actually twelve quilts (40 lbs) on their way (tomorrow) to the victims of the fires in northern Washington, scene of the worst wildfire in our state's history. It's an hour from here to Brewster (Anderson Field), or over 3 hours by car. The Phoenix will let us view huge areas the fire has burned in the last month.

The quilts fit in more easily than I thought, and the space behind the oxygen bottle is unused. I'd taken everything out of the baggage area, but after the quilts were stowed, I put the tie-downs, canopy cover, jacket, and the step stool back in. Still space left!

Australian Flying

Attached are some photos of my plane on a recent trip to Fraser Island which lies off the coast of Queensland (about 90 minutes flying time north of Brisbane).  The airfield as you can see is located right on the beach with a pub 50 meters from where you park your plane.  There is plenty of accommodations within walking distance.  Its a great place for a fly in.
Cheers

Grand Junction to Salida to Taos to Home

Winds were still predicted to be high the third day in Grand Junction but we didn't have far to go this day so we decided to launch, get a feel for the air, and either return and land or carry on to Salida.  Well, it was very windy, 40kts+ at 16,000' but the air was no worse than what we encountered from AZ to CO a few days before so we kept going.

 A bunch of glider pilots were having a fly-in at Salida, but after our reports of the upper level winds they all decided to take a day off.  We spent a couple of days with JZ and Amy.  Our plan had been to fly south to Taos next to visit friends but we had had enough of the winds and turbulence.  Amy loaned us her Yukon to drive to Taos instead.

 We had a great hike with Tina, Liza, and McKenna in the mountains of Taos.

 I got to see a few good friends from the Taos Ski Patrol including Ricus and Eric here.

 Back in Salida, the winds had finally dropped off, so JZ and I took the Phoenix to 17,999' over the Collegiate Range.  JZ's Phoenix better arrive soon or he is likely to kill me.

 JZ has plenty or room for his Cessna 320, RV, and Phoenix in the hangar.

 Shortly after departure from Salida, we viewed the Wet Valley looking south with the Sangre de Christo Range off the wingtip.

 The Skyview now has the capability to display their "6 Pack" view, so I played around with it.

 Lunchtime.

 We had to land in Georgia and wait for the storms along the border to die out.  Then it looked better on the iPad, so we launched into Florida.  There were isolated storms to fly around, such as this one.

 This is how the Skyview depicts the storm in the photo above.

Flight following took us over the top of Orlando, then it was home sweet home.

Cottonwood to Colorado

 After we left Cottonwood heading northeast we crossed the Moenkopi Plateau. View to the right...

 And view to the left.

 Then we crossed Monument Valley, but the winds were to strong to be low. We have flown through Monument Valley on previous trips, treating the free standing rocks like a slalom course, so it was neat to see it from higher up.  Most of the flight to Grand Junction were in winds of 30kts or more with considerable turbulence, so we had to fly slow, below Va of 97kts, and also hand fly the plane rather than fly on autopilot.

 Our friends Terry and Chris picked us up at the airport and then we took a little hike in Colorado National Monument.  It was nice to be on the ground.

 We stayed with our friends 2 nights because of the strong winds aloft complete with wave clouds.

 Terry is a falconer and currently has a gyrfalcon.

Wow, the Colorado mountains and woods sure are beautiful.
