Sonex

This is the drawing tree for the Sonex Aircraft. Your start at a branch on the bottom and work your way up. When all the branches of the drawing tree are complete, your airplane is also complete.

These are the wing skins and as you can see, they are pre-drilled for assembly with the ribs and spars. The holes are actually undersized, so Clecos can be used for temporary assembly, then the holes are drilled to the right size and blind rivets are installed. The pre-drilling for the rigging is a incredible time saver.

The gear legs are titanium. Phil said they were a bit tricky to drill to install the retaining bolts.

This is the one piece, roto-molded fuel tank.

Engine cowling halves

The cylindrical copper colored devices are Clecos - basically a temporary clamp that holds multiple pieces of sheet aluminum in place via the rivet holes. These align the parts while the holes are being drilled to the correct size and rivets are being set (installed).

The tailwheel is basically a grocery cart wheel - functional, light and cheap.

This is the engine mount for the Aerovee engine.

This rectangular cutout is where the wing spar passes through the fuselage.

The rudder pedals ride on a phenolic bearing block for low friction and long life.

Wheel pants

The tail gear rod is also titanium.

Phil, a builder in Logan showed me his Sonex project this weekend. He has completed most of the fuselage and tail and now is going to start on the wings.

I am very impressed with the whole Sonex aircraft. It is very affordable, relative to all the other Light Sport Aircraft- about $26,000, including the Aerovee engine (A VW derivative).

The kit is very complete and the skins are pre-drilled to allow assembly with Clecos. Then, the undersize holes are drilled out and blind rivets are installed. These are visible in all the photos shown here.

Kitfox IV

John Kerr is also the builder and owner of this Kitfox Model IV with a Rotax 912. He was kind enough to give me a ride around the patch last Saturday after the monthly fly-in breakfast at Leading Edge Aviation at the Logan-Cache airport (KLGU).

Here is a video of our landing.

All in all, it was a blast!

Challenger Experimental Aircraft

Jerry, a friendly, fellow aviator from Logan made the trip over to BMC to give me a ride in his Challenger LSA. He built it from a kit over the course of some months. He estimated that it took him about 300 hours to complete the kit.

The plane is powered by a Rotax 503 DCDI (dual carbs and dual ignition and 50 hp) and geared down to turn a 60 inch prop with a synchronous belt drive. (Which, by the way I have blogged about before, but this application seems to be one of the successful ones.)

The tandem seating arrangement was a little tight for me, but I am tall. I tried the front seat and it was adequate, but a little difficult to get into. I guess that's just the price of trying to fly inexpensive aircraft. If I were loaded, I would buy a Cessna 172 XP. They have ample cabin room for me.

Jerry added cabin heat by putting this intake on the cooling shroud (the Rotax 503 is fan cooled) and ducting the hot air to the front of the cabin. Canadian Challenger owners also do this to keep flying through the winter.

Here are some videos of the flight.

Bottom line; I liked the Challenger. It did pretty well for only having a Rotax 503 at gross weight and 4,200" field elevation. I like the ease of construction (aluminum tube and rivets and Stits fabric) and the tricycle configuration. I'd like to find a used one that I could buy.

Culture

The self-educated individual – confident in his gender, his heritage, his religion, and the traditional culture that he seeks to project into the future – stands as a threat to the very existence of the state: He does not need its ministrations.

Where then to begin the creation of capitalist culture? The destruction of the moral pretenses of the state is the irreducible first step toward the realization of a capitalist culture….

Terry Hulsey

I would add:

The destruction of the moral pretenses of the state is the irreducible first step toward preserving traditional culture.

Delusionists

The delusionists are those who believe that the current system can be reformed, made more efficient, streamlined. The delusionists believe that government bureaucracies act on market-like incentives. The delusionists believe that those in government bureaucracy can be convinced to reduce their role and influence. The delusionists believe that the president is in control of the bureaucracies. The delusionists believe that government bureaucracies are led by good people just trying to do the right thing. The delusionists believe that individuals, acting as central planners, are even capable of identifying the right thing to do.

The State

"A state is absolute in the sense which I have in mind when it claims the right to a monopoly of all the force within the community, to make war, to make peace, to conscript life, to tax, to establish and disestablish property, to define crime, to punish disobedience, to control education, to supervise the family, to regulate personal habits, and to censor opinions. The modern state claims all of these powers, and, in the matter of theory, there is no real difference in the size of the claim between communists, fascists, and Democrats." - Walter Lippmann

Solving the Crisis of American Schooling

"The logic of compulsory schooling in the middle of a democracy is a contradiction of the original national charter; it breaks the contract of the Bill of Rights, using as its justification the excuse that kids can't learn any other way, that they can't be trusted with responsibility. The truth is exactly the opposite: unless they are trusted with responsibility they cannot learn much, and under the thumb of central compulsion the lessons they do learn are bad ones."

John Taylor Gatto, "A Different Kind of Teacher", pg. 193-194

Robert P. Murphy

In particular, the market interest rate coordinates the "intertemporal" (i.e., across-time) activities of investors, businesses, and consumers. If consumers become more future oriented and want to reduce consumption in the near term in order to provide more for later years, what happens in the free market is that the increased savings push down interest rates, which then signal entrepreneurs to borrow more and invest in longer projects. Thus resources (such as labor, oil, steel, and machine time) get redirected away from present goods, like TVs and sports cars, and the freed-up resources flow into capital or investment goods like tractors and cargo ships.

Now when the Federal Reserve artificially reduces interest rates below their free-market level, it sends a false message to entrepreneurs. Firms begin expanding as if consumers have increased their savings, but in fact consumers have reduced their savings (due to the lower interest rates). Businesses that churn out durable goods, such as furnaces, cargo ships, and, yes, houses will find business booming, because these sectors respond positively to low interest rates.

On the other hand, other sectors don't need to contract, because (unlike the scenario of genuine savings) nobody is cutting back on consumption. This is precisely why the Fed-induced boom is unsustainable — real resources have not been released from consumer sectors in order to fuel the expansion of the capital sectors. Because modern economies are so complex, the charade can continue for a few years, with entrepreneurs cutting corners and "consuming capital" (i.e., postponing necessary replacement and maintenance on equipment) while both investment and consumer goods keep flowing out of the pipeline at increased rates. But the music eventually stops, since (after all) the Fed's printing of green pieces of paper doesn't really make a country wealthier. When the Fed "cuts interest rates" it isn't really creating more capital for businesses to borrow; it is instead distorting the signal that the market interest rate was trying to convey.

Gary North

Gary North recently wrote a great article on the politico-economic outcome caused by the anti-nuclear media forces following the Japanese earthquake and tsunami:

"Energy is the key to output. This has been true for over 200 years. To control a primary source of energy is to get rich. China will be able to buy uranium by means of its output from uranium. It will convert uranium into wealth. It will do so with the lowest energy cost-per-output ratio of any nation. Its people will find employment.

I think this has shifted the balance of economic power away from India. India will face public resistance to nuclear power. China will not. India has a lot of advantages: English, the legal system, the free flow of ideas, and a lot of motivated, well-educated people. I am not saying that India will fall behind the world. It will advance. But with respect to the job market for millions of recent arrivals from rural districts, nuclear power will give China the edge.

The anti-nuke forces will never talk about this in public. They will never say publicly, "We have delivered the world's economy into the hands of China." But they will have done just that."

Lew Rockwell - again

The beauty and glory of economic science is that it consists in a series of laws and principles that do not change according to time and place. The prescription for prosperity and stability and human economic flourishing is always and everywhere the same: freedom of association, freedom of contract, freedom of enterprise, freedom to trade across borders without penalty, sound money that is redeemable in something besides paper, private property rights, wages and prices that adjust by market conditions, and a legal structure that shores up these institutions rather than undermines them.

James H. Polve

“Mechanical engineers design and manufacture machines, machines to help mankind, to ease his burden and to make like more abundant. Machine work supplants slave labor and provides power far in excess of muscle power to free men from hard labor and yet provides the means to accomplish. Automobiles, airplanes, tractors, electrical and nuclear power plants, steam plants and many other similar kinds of plants and machines are typical examples of design and manufacture by the mechanical engineer. His special abilities are aimed at coupling natural laws with natural materials to produce work. He channels energy available on earth, and wherever possible in the universe, through devices into more usable forms to aid man. He can multiply man’s strength and quickness through hydraulic, pneumatic, and electrical devices. He can transport men and goods faster, further, and more efficiently than man can walk or carry. He provides for warmth in the winter and coolness in the summer. He is aided and yet constrained by the physical laws and the characteristics of resources that surround him; and yet he has made great advances to free men somewhat from the edict ‘In the sweat of thy face shalt thou eat bread, til thou return unto the ground’ (Gen. 3:19).”

Ted Rockwell - The Best Quote Ever

That tactic, of making problems out of advantages—making sow’s ears out of silk purses, I call it—permeates the whole nuclear enterprise. The advantage that radioactivity continually and automatically gets less and less toxic every day, is converted to, “it stays toxic for thousands of years.” And this is implied to pose an unprecedented problem that humanity is not equipped to deal with. And breakable light bulbs containing mercury are called “green,” and radioactivity is called uniquely hazardous.
