Hangar Flying / Re: NorCal Fuel Prices
« on: November 28, 2012, 10:21:13 AM »
Yeah, I fuel one tank with mogas at Lebanon when I go cross-country.  But I can't use it for local flights (low altitude, high manifold pressure) due to my engine's 9.7:1 pistons.

If you're a regular at Lebanon, you'll know Tebo.  Sadly, he was killed the other day:

Funny (in a sad way) how $4.89/gallon for 100LL seem like a bargain these days.  :-)

Fuel is still $5.60 at both FBOs on my field (Independence, OR).  Wholesale prices have dropped but I suspect they need to use up the stock they bought at higher prices earlier in the year.  Fortunately, my O235 Long-EZ is economical (5 gal/hr): I feel nowhere near the pain that my neighbors do when they fuel their Bonanzas.

Looking forward to some of that "bargain" 100LL when I go cross-country to southern California later next month.

For the standard Brock fuel caps, I use the Viton fluoroelastomer equivalent of MS29513-325 purchased from McMaster-Carr (


Hangar Flying / Re: Belleville washers to hold props on?
« on: December 28, 2011, 10:37:48 AM »
I'm curious as to how many carnard drivers are out there that are using Belleville washers to secure their propellers?

I have been using them (in accordance with instructions from Marc Zeitlin and Gary Hertzler) for the past 2-1/2 years.

I for one have converted after discovering that my prop is no longer air worthy.  I just no longer believe that bolt torque is a good (safe) measurement of the force needed to keep the propeller on my plane.  Do you feel the same way?

No.  I have total confidence that bolt torque is a "good (safe) measurement of the force needed to keep the propeller on my plane".  And note the words "good/safe" -- it's good enough if done right.  But I don't have total confidence in my ability to maintain that bolt torque without frequent checking and adjustment, which is more work than I'm willing to do.

Have you ever come close to loosing (sic) a propeller in the air?

No, never.  But then, I would check bolt torque 3-4 times a year (in my pre-Belleville days).

Congrats Joe!

Dale Martin took (and apparently submitted) that picture and deserves the congrats.

The scene is crossing the Cascades en route from Creswell, OR to Lewiston, ID.  Other shots of N821RP here:

I used the Barry part number 94150-40 on my O235-L2C Long-EZ (with a Brock engine mount).  They're $77 each from Aircraft Spruce.  I have no experience with the "heavy duty" parts you mentioned nor the Wicks EM100-005 which I was once told would work too.

The parts for my engine/mount are 2-3/8 inches in diameter.  It would be helpful if the catalogs would specify dimensions in addition to which Cessna or Mooney they fit :-(

Also, when braking at slower speeds I sometimes get some shimmy in the main gear legs.  If I let go of the brakes it stops.  Seems to happen at slow speeds, anybody else have this phenomonon?

I did until I replaced the brake discs with new Rapco discs (about $80 each from Aircraft Spruce; see 

Gary Hertzler had advised me that would fix my shimmy problem and he was right.  Seems a warped disc will excite the main gear enough to cause shimmy at a certain speed range.  My old discs had about 1000 hours on them (although that's hardly a measure of their use) and didn't seem terribly warped or grooved but they were too thin to true up (too little material left).

Hangar Flying / Re: Kanab EZ Fly-In Update
« on: September 06, 2010, 06:38:33 PM »
Thanks for your comments, flyingwaldo and Bruce.

I'm back home now after logging 12 hours flying time this weekend.  There were so many good activities that it is hard to decide what the best part of the fly-in was:
  • Hanging out around the pool at Aiken's lodge listening to Mike Melville talking about Space Ship One and Two and other interesting things. 
  • The hike up the red rock mountain just north of town.  David Orr led about 16 of us right after the pizza at Aiken's Lodge.  8 of us persevered to nearly the top but by then it was pitch black.  We did have flashlights but the other 8 (smarter ones) turned back a little earlier.
  • The "timed event".  Ten of us took off in 30-second intervals and flew the old race course (about 85 NM) at W.O.T. and received a speed score from Char.  Actually, due to cooling issues my O235 Long-EZ couldn't run W.O.T. so I pulled off power at the first turn and my speed was disappointing, but it was fun nonetheless.
  • The awards banquet at Nedra's Mexican restaurant.  We laughed at Char's comment that 10 of us competed in 8 different events (we ranged from a Glassair III and a Berkut to a VariEze nearly 100 MPH slower.)  She presented "speeding tickets" to the participants after dinner.  Alas, mine was left behind in the motel along with some other paperwork so I can't give you the full "race results" but suffice to say that the O320 Cozy's and Long-EZs were very impressive.

Char and Gary Spencer should receive kudos and our thanks for organizing this.  At first I was apprehensive about the travel distance but I'm very glad I went and am already counting the days until next year.

Hangar Flying / Kanab EZ Fly-In Update
« on: September 04, 2010, 02:59:38 PM »
Yesterday after 5 hours of flying in a straight line describing diagonals of Oregon and Nevada, my blond ballast (Harriet) and I arrived at Kanab (KKNB).  (Flight track:

This is what the ramp looked like at about noon today:

More EZ arrived after this was taken including Marc and Deanie Zeitlin, Tom and Myla Jewitt, and a fair number of others whom I did not know.  A fourth row of parking (to the left in the picture) was being used.

Earlier in the day, Jim Price, Rob Martinsen, and Harriet and I flew out to St. George, UT (KSGU) for breakfast.  Flying back to Kanab I noted an O.A.T. of 73F at 8500 MSL.   Perfect weather for lounging around the pool at Aiken's Lodge for the afternoon until pizza and beer this evening.

Tomorrow there's a pancake breakfast on the airport, then the "timed event" (formerly known as "the race", and then a dinner finale at Nedra's Mex/American restaurant.

Nice way to spend the Labor Day weekend.  Thank you Char and Gary Spencer for organizing things.

Hangar Flying / Re: Paint Stripping

Is there a way to strip just the topcoat and leave the primer?

You sould look into sodablasting ( as the "depth" of the stripping is controllable and the process is compatible with composite construction.  While I don't have any firsthand experience with it, that never stops anyone from posting anything about anything in these forums :-)

Joe, what model did you use from their catalog?  And are you having any (de)frosting issues? 

I believe the heated seats in the catalog are identical except for the wiring termination.  I wired mine to ship's power so I used the "WarmSeats Seat Heater (Waterproof)" model  The complete seat heater (two cushions) draws just over 2A in the "Hi" setting after I trimmed it to fit my upholstry.

There is enough of an air leak in the cockpit so frosting/fogging is not an issue in my aircraft.  :-(


Hangar Flying / Cold Weather Flying
« on: February 22, 2010, 03:42:28 PM »
Earlier today I flew my O235 Long-EZ home to Independence, OR from a visit with Jim Price at Sunrise Skypark in southern ID (;7S5&view=vfr).  That's about 300 NM of inhospitable terrain (including 10,500' Mt. Jefferson in the Cascade Mountains) with hardly even a decent road for an emergency landing. It's still winter in Idaho and the little Lycoming likes the colder temperatures so I climbed to FL190 to buy myself some more gliding distance.  And while I was at it I wanted to see how my heated seat from would handle the cold (-6F at altitude) as I have no cabin heat.

It was a non-event.  The aircraft still wanted to climb and FL200 would have been easy although that's higher than I wanted to be with my current oxygen system.  I switched my seat fron high to low heat setting as high was still too hot.  The manifold pressure indicated 14 inches at WOT and with 2700 RPM I estimate 52% power.  My Garmin 196 GPS needed a large contrast adjustment as the LCD screen became dark in the cold.

GU canard, Hertzler propeller, about 30 gallons of fuel, solo, with darn little luggage.  And heated socks, although I didn't bother with them for this trip as I've found regular heavy wool socks and boots are OK for a couple of hours.

Hangar Flying / Kanab Fly-In
« on: August 19, 2009, 05:11:32 PM »
I'm afraid it isn't well-publicized but the Kanab (UT) fly-in (formerly the Kanab R.A.C.E.) will be held in another two weeks (September 6-7 at KKNB). 

Anyone going? 

Hangar Flying / Re: Arlington Canard Fly-Out Dinner
« on: July 16, 2009, 08:31:59 AM »
You left just in time Joe!  Gil, Larry, Brian and I woke up to 1000' ceilings and rain Sunday morning.....

Yeah, I didn't need any more of that after scud running to arrive on Thursday.  I would have liked to stay for Saturday and even Sunday though.

OK, I figure "Gil" == Gil Hutchison (sp?) but who are the other names you mentioned (including yours -- to whom am I talking?).

Starting Thursday afternoon, the weather was good: sunny and warm but not too hot.  Wednesday was a different story and even Thursday morning was low overcast.  A lot of us bugged out Saturday morning in advance of thunderstorm buildups that did not materialize.

The usual suspects were there (Tom Staggs, Dale Martin, Tim Sullivan, Bob and Linda Evans, Joe Person, Joe Hull, Joe Dubner, Dave Viglierchio, Bruce Hughes, Brian Amadala, Mike Sabourin, Rich Martin) and some new blood (Jim Price, Tom Smith, Chris from Colorado, and a gent flying a Speed Canard).  Please excuse my spelling and any omissions -- I did not take notes and I didn't meet everyone as I slept in an RV (motorhome type) this year. 

We had 7-9 airplanes fly out to Bremerton for dinner Thursday night and it seemed like there were 20 of us at the seafood restaurant on the field.

I'd like to publicly thank the "locals" that made the fly-in such an outstanding experience for us "out of towners".  Rich Martin did a lot of set up work with a shade tent, chairs, and drinking water.  I don't know who's responsible but two large BBQ grills and other equipment appeared.  Thanks, guys.

And a special thanks to Tom Staggs for his organizational work, making the Friday BBQ happen, and the outstanding aerial tour of the Puget Sound and Seattle that he led us on.  We saw submarines and aircraft carriers, Boeing 787s parked on the ramp at Paine Field, and downtown Seattle with the Space Needle, all close up and personal.  There were times it sounded like we knew what we were doing ("EZ flight check - 2 - 3 - 4 - 5 - 6") and times it didn't ("Who's number 4?", "OK guys, lets try it again." :-)

You can see the APRS track of our tour at this link.
