Hangar Flying / Re: Crummy Review
« on: May 31, 2011, 06:05:47 PM »
Congrats Steve and Mike on making the cover and having your beautiful VariEze described for the world to see. I am sure all of us are a little jealous, in a good way. If I read the article right it seems that you have accomplished an amazing personal goal by fully completing a second aircraft. Many of us are still trying to just get one done. And then some of us are in a further distant group that never really expects or intends to "finish...."
The disappointing elements you mentioned were suspected. And you fared better than a friend that had provided a near perfect set of pictures and text to a magazine, but was not happy with the result, and still isn't. So good for you guys! I think your aircraft is a great example for displaying the results of the distillation over the years of Burt's pivotal design. Great job.
I do hope this will inspire others in the group that are capable and prepared, to put their plane in the spot light. The CSA newsletter has a supportive audience and is a good start for practice.

"Kinda like putting a beautiful babe on the cover, and inside, a technical treatise on how a woman's elbow works."

That was one of my first thoughts. However, I expect that the author Bob Grimstead hit his mark and would grade it as an A or A+, and rightly so. 
My second thought is, I wish for anyone attempting to present a treatise on this particular subject, that they could benefit from living in the nurture of an Eze a little longer than this quick low pass. Very likely the pilot would come to naturally do things like lead the turns (in the VariEze) with a little rudder, and with more of a relationship might notice that any project can take a long time to finish or may not be finished at all. That content might more closely resemble what those of us would include that are fortunate enough to have cycled through several realizations of the VariEze experience.
It might have been just as well without some of the Dead End content, but I expect the author got it exactly as he intended. I really like Kitplanes, especially Barnaby and Robrucha, and consistently use the aircraft reports as references. So far none of the excellent reports has resulted in convincing me to change airplanes  :)
Evidently Steve Brown was very deliberate about the details of this second VariEze, and maybe he should provide us with a private rest of the story.

More thoughts on the practical considerations on operating above gross weight.
Two unidentified pilots were returning from a fly in, descending from altitude for landing. The GIB, guy in back, was flying and pushed the nose over, increasing the airspeed to about 190 mph, enjoying the rush. The front-seater pulled the power back and said he had the airplane. The GIB asked what’s wrong, he was just trying to speed up and take advantage of the descent.

The front-seater said that they needed to slow down. The GIB asked what the problem was, because the Vne, max speed, was 220 mph.
The front seater said he expected that when they got down to around 4000 feet where the base of a scattered cloud layer was, that they would probably hit some turbulence. The GIB scoffed and said so what, it’s a strong airplane, and he was only doing 190, and the Vne was 220.
The front-seater, an engineer, had just bought the plane, and had done his homework. He said that with the probability of turbulence that he would be slowing closer to the maneuvering speed, 140 mph.
Descending through 4000 feet they did experience moderate turbulence.
The GIB asked him to explain his concern. The engineer talked through a quick calculation including their weight, which was near max gross, a speed of, say, 200 mph, and how many Gs they could have experienced. He concluded with the fact that the airplane wasn’t designed for that, and the he expected that the structure would in fact fail in that scenario.
One question might be, if a new owner decides that his max gross weight is, say... 1600 lbs, what is the maneuvering speed? And the Vne?  Again, these are concerns with any airplane.
The point here is the effect of operating your aircraft above design max gross. Curiosity of maneuvering speed and penetration speed would involve personal study, should one be interested… :)

Hangar Flying / Re: What killed the Long EZ?
« on: January 15, 2011, 10:52:15 PM »
Not the answer to your question, just an observation on the perceived numbers of EZs.
It’s not a landslide, but I can’t help but notice the number of VariEzes still being built out there.
And the number of VariEze guys that have a LongEZ or Cozy coming together in a back corner of their hangar.
This year at RR there was a very interesting and enjoyable group of VariEze guys there, still flying or cooking on some burner or another, flying their Vari regularly, or too busy with ‘something’ to get out and fly as often as they want to.
And if you are active and flying your canard plane much, you are probably getting plenty of contacts from new builders or rebuilders.
In October I put out a tongue in cheek report on a friend with the oldest VariEze that still didn’t quite make it to RR this past year. It was inspired by the number of guys that are still mixing epoxy and dreaming of first flight.
Just an observation…  :)

And for angle of bank, also an element of your initial question, see the Jan 2011 Sport Aviation, page 52, 4th paragraph. Arnold Ebneter's interesting solution to testing his plane to determine fuel burn at gross weight, when he only intended to fly 20 minutes per test flight and his landing weight was hundreds of pounds below gross....

Hangar Flying / Re: Gross weight question - long EZ

You mentioned the practical aspect of operating over gross weight. Several things come to mind.
One, maximum landing weight. We have heard that the gross weight value of 1080 lbs was used hundreds of times when designing the VariEze. The allowable gross weight was later said to be 1120 with a bigger engine, but the max landing weight was still 1080.
An example, the first Long EZ was flown 33 hours non stop. Yes it would get in the air even though massively overloaded, but the gear structure was still designed for 1325 lbs (I think that was the initial value). Also, a cable was needed to hold the gear struts from flexing outward on takeoff. They were concerned about being so heavy if they had to land soon after takeoff.
 When evaluating whether our particular aircraft could be operated at over-gross weights we are tempted to see ourselves milking through a feather soft landing. But actual over weight use often results in the gear being rebuilt. True with any type airplane.
Two, minimium speed. Particularly in an unplanned off-airport landing. Several years ago I read about a bush pilot that used an angle of attack AOA needle/plate on the wing strut to check that his approach or climbout AOA was optimum. Not speed, AOA. AOA worked perfectly, every time. Even on Navy carrier approaches  :)
The practical takeaway was that his low weight approach speed was around 60 and his high weight speed was around 95, both at the same AOA. His cruise speed was not much higher  :)
A particular wing will always stall at the same AOA. But the stall speed varies greatly, dependent on weight. For our stall-resistant aircraft design, this critical factor is minimum speed. While we may focus on approach speeds, the real issue is minimum speed. In the bush plane example, his cruise speed was not much higher than his high-weight approach speed. For our speedsters, we can also overload the plane such that the higher minimum speed greatly reduces the probability of a successful off-airport landing. Because of carrying too much energy into the mix.
And there’s more. Its not just minimum speed. The approach speed includes the requirement to have enough extra energy to flare and dissipate the rate of descent. Several years ago a fighter guy flew his Long EZ through a pattern simulating a high rate-of-descent accident scenario. He determined for the flare on a normal landing his LongEZ would need an approach speed 22 mph above his minimum speed.
How do you determine minimum speed?  I know mine.
For a builder, per the POH, this is accomplished during the restricted period at altitude, preferably with a parachute.
For a buyer… depends on the buyer I guess.  Again, it is important to know and observe these speeds in any aircraft.
All said, I believe the EZ design provides superb all around flight qualities and capabilities, and an optimum airframe for exercising our passions.

A friend bought a nice looking, well equipped EZ with a big motor. One day soonafter he came in the hangar kinda pale. He said that with the weight of him and his wife there was room for only 2 gallons of fuel. He doesn't have it any more. He egged me into a race twice, once after installing new wheel pants, each time extremely frustrated that he couldn't keep up. Weight counts.
I once heard of an 0-320 VEz with a min speed of about 100 mph...

« on: January 10, 2011, 06:22:43 PM »
Please stay on good subject of VE wing attach. But an aside on design ramifications-
Standing by one of dozens of LEZs on the Mojave ramp, someone asked Burt what he thought about not installing the lower winglet.
The answer included quickly sequencing through the installation, but going well beyond the expected considerations. All said to agree with your points Dale and Joe, and also to encourage the discussion-

Hangar Flying / Hill Country Christmas
« on: December 24, 2010, 01:34:43 PM »
The Eze growls strong and smooth over central Texas. The 42 mph winds that I initially discounted when flight planning are now threatening to extend the normally 1.5 hour trip from Fort Worth to San Antonio and make me late for a meeting. Instead of leaning to 2200 or 2400 rpm, the mixture is kept up at a hair lean of peak with the rpm at 2500. The actual headwind is only 22 mph so running at max cruise will get me there on time.  

A good portion of the previous evening included visions of sugar plums and a heavily aviation-APPed iPad dancing in my head. I had recently observed a friend surround himself with one; getting all the good stuff on it, with the iPad now having become a new “significant-other” in his life so to speak  :)  Lots of quality time together.

However, back to reality and basic-flying here, the nose is periodically nudged back to 6500 feet and 210 degrees, with the airplane describing gentle horizontal and vertical sine waves cruising across the undulating hill country below.

The wing-leveler hasn’t moved from The List to my panel yet, and the yeoman GPS has been a member of the spartan cockpit equipment for about a decade. Basic. Over the trip down and back today I will come to again appreciate the airplane’s svelte ‘antiglass’ component suite with the GPS direction arrow and altimeter being the primary distractions from the outside vistas, and the sound of the purring engine leaving the cassette player mostly unused. Just kidding, it’s really a portable CD player that I don’t get around to using  :)       No, not an 8-track either.

The sky is brilliant blue. The temperature today in mid December will be 70 degrees. Looking up past the GPS direction needle, the bug splat on the canopy is held targeted on a distinct shape on the horizon as a course marker.  Even with the headwind those distant aim-points slide under the nose at a gratifying rate. Time to flip the sectional.

Vistas of the hill country to the west remind me of places to swing over and check out on the way back. The list includes looking forward to a vibrant moment or two running that granite-floored riverbed down there, and a little further west, checking out that partially framed dream home that I stumbled across several years ago, set inside the elbow of a secluded ridgeline in a spectacular winding rock-chiseled ravine that is sometimes a raging river. Evidently.

The day is spent consulting with an official that happens to have been a school friend. Our itinerary includes lunch at his favorite Mexican restaurant out in the middle of nowhere. Looking back, the day has now settled out to be among one of my favorite days. Since renewing our friendship several months ago the friend has become several chapters in a book. And those pages are spent just trying to describe him and what he does. Riding in his truck you notice that the radio is gone. It looks like he grabbed the radio and jerked it out and threw it out the window, and now keeps his chaw and cigars and the tools of his trade in the hole in the dash. I haven’t seen burdizzos in a while.  

Preparing to depart for home from the historical Alsace community, a small group looks over the plane. I fill the tanks full with $3.49 Avgas. It starts on the third pull. I succeed in resisting jumping and punching a fist in the air. Taxiing out there is a Cessna grunting around the pattern. I remind myself to take the other side of the pattern.

On takeoff the Eze climbs strong into the wind, turns and zips downwind, and with a waggle of the wing lofts briskly to the north. Climbing out through 4000 feet the plane seems to slide gracefully onto slippery glass.
Leveling at 7500 feet the air is smooth as silk. The GPs says the trip home will total about a forth less than normal.  With a smile the mixture is leaned a little more. This is where the pure simplicity of the plane rises up and is refreshingly inhaled and savored again. Better even than epoxy fumes. That’s a joke. The epoxy fumes. Rather, it’s really ginger snaps and milk that work the magic.
Running the granite lined river bed will wait for another calmer day. The winds down there would be brutal.
Oh yes … the partially framed dream home. Over there to the left a little, if I can find it again. I think its over that set of ridgelines. I think this is the right river. Topping the black bush thatched granite peak and swinging back along the chiseled butte, I’m thinking – I love the way this airplane flies – I’m thinking it must have been some really impressive water flows to cut through that ridgeline.
The dream home is finished. Six columns. Drifting down toward the river bed, above legal altitude of course – especially with the winds over the ridgelines today, you can see that the front yard holds a turquoise swimming pool and faces an imposing black and white granite cliff across the river. In the back yard there is a tennis court and several outbuildings. A dirt road winds out across the rolling hills and disappears into the distance. No runway. No helo pad. To get out here, they really have to want to get out here. I think about Freedom. I think about Time. What would it be like to have them? What would it be worth to control them.

Rolling back north, the dozen or so unmarked black ranch airstrips appear one by one out across the open expanse of the hill country. I silently congratulate those that fly off of the pristine strips, and if they are not marked, I mark them at their blank space on the sectional, and the GPS, hoping never to need them.
Here it comes again. Under the rumble, an unheard sigh of joy. Sitting here doing this. In this vibrant steed. Outracing the wind. The overwhelming magnificence of the blue sky above turning turquoise and bronze, permeating down to the blackening horizon. I have been here before. They are always here. But it’s special again. Up here. How can I stay up here more? The Wright Brothers would have killed to be doing this. Maybe not killed… but something dramatic….  
I wonder again how do these molecules hold together, and then I remember again; You Are Wonderfully Made….
How lucky was I to grab this dream, this airframe that does so much besides defy the laws of gravity…no, prove the laws of gravity. How can I comprehend… What experience can I capture…?  What picture can I take…? What words…?
And again I just relax and sit back and enjoy and let the shapely foil of molecules do their thing. The shot of the winglet on the sunset does turn out pretty good.

The towers of downtown Fort Worth are unseen in the distance, but they laser the crimson sunset back at me off their golden windows. The GPS says Approaching VNav Profile. Descending through 3500 feet over the Brazos River the air comes alive. Slow down. The waters in the river and lakes are tightly rippling.
Arriving home includes an overhead approach and a tighter bank angle than normal to stay in the county. Turning final at 400 feet, past experience reminds me to be on my toes. In a relaxed hand the stick comes alive  and will be gently stirred all the way down. We’ll be flying all the way to the hangar. The rudders respond with a wiggle and are ready. I hold an extra ten knots. Slowing down on ground rollout will not be a problem.
Winsock is straight out and skittish. Slight crosswind. Across trees and hangars. A friend refers to these moments as sporty. Gear down check the third time.
On final the windsock continues to flitter as I motor past. There’s the burble. Sporty indeed. Left main, right main, left main, settle there now, won’t need a go-around. Probably.
The landing is likely the most challenging of the thousand or so in the plane. Taxiing in unscathed it is apparent that mixing the stick (no gorilla grip) and aggressive rudder were a good part of the landing.
 I could log three landings. I wonder if Bob Hoover does when he does that on purpose. Probably not.
A well-deserved day off from work. An out and back over the Hill Country. A purdy good way to spend a Wednesday. And your birthday.
It’s late. The ginger snaps have worn off. I will again wake up in the morning in the 1970s. Thinking about what an Eze should really look like.
 
Merry Christmas Y’all.  I hope we all get what we want. Not what we deserve  :)

« on: December 05, 2010, 09:03:14 PM »
This has been said several ways, but to nail it down   - the best foam for a new Long EZ or VariEze fuselage is the LongEZ foam as specified in the LongEZ plans, per the plans. Order it from an approved source like AC Spruce.
Be aware that the fumes from hotwiring this fuselage foam can be fatal.

Hangar Flying / Re: heat gun to soften then twist composite gear leg
« on: October 31, 2010, 04:38:30 PM »
No I have not seen a twisted nose strut. Try to get some other eyeballs on it, particularly eze types. Maybe it was home made. I don't know how one would get the strut hot enough to deform, which raises the question of whether the strut was bent while at normal temp, with the possible weakening. Of course there isn’t any foam in the strut, and if needed, only flox should be used in attaching it, not micro.
To your question, trying to re-twist it, enough heat could cause an epoxy void. Thus my thought is, if it is still totally sound, pop the fitting off and re-attach it.

Since I am rambling, on heating the strut, to elaborate a little on the one i fixed, the obvious problem to the owner was the constant need for right rudder while taxiing. He thought the right tire was not aligned correctly. Examination revealed that with the constant braking, even on takeoff, the right gear strut had overheated, with the combination of flexing, there was an epoxy void and the strut was weakened adjacent to the brake disc. He believed the problem was there before he bought the plane.
We tapered and rebuilt the lower strut to original shape. When we took the external wraps off of the lower strut it easily bent and came off at the top bolt holes. (The strut repair has been good now for about 10 years). After the repair he expected the plane to taxi straight. It didn’t. it had the same problem of turning left. I joked that it was a NASCAR airplane. He wasn’t interested in joking around.
To the rambling point. The problem was that the nose wheel fitting had been installed at a canted angle. I noticed it after we had fixed the strut and he was climbing in and out of the plane. If the airplane was wiggled the nose wheel would turn about 10 degrees to the left, which was its “natural neutral point.”
I popped it off and put it back on. He taxied it and came back in smiling big, wanting to know where I had hid the power steering pump. Effortless taxiing.
Installing the fitting striaight is straight forward. Holler if you want a walk through on that anyway :)
