China's DIY Aviators Take Flight 113

Posted by samzenpus from the Icarus-lee dept.
ScuttleMonkey writes "China’s emerging aviator class is spreading its wings with a plethora of approaches, from the ramshackle to the sophisticated to the potentially revolutionary. They’re using everything imaginable, from old motorcycle engines to electric motors to even their own legs, like Mao Yiqing and his human-powered airplane. You could easily plot these adventurous innovators on a graph, with the X axis showing their skill and the Y axis their financial means."

      Half of every dollar spent on aviation in the US goes to cover liability. Also, Cessna, by far, has the largest markup of any of the light piston US manufacturers.

        I wanted to clarify something here. That was meant to be taken in relative terms rather than an absolute. In absolute terms the death and injury rate is actually pretty low; with the most dangerous segment being on par with motorcycles. In relative terms to what it could be, its far higher than what is otherwise technically obtainable.

      • You say that as if you need no facts to back it up. Looking around, the best estimates I could find were 3 to 5 percent of the cost of a plane are litigation and litigation-prevention costs. There's also a fairly significant amount for insurance, some of which goes to paying for litigation, but all totaled it still seems to be less than either of the two largest costs, parts and labor.

        So, please stop pulling numbers out of your ass.

        • The problem is that those numbers are devilishly difficult to calculate. It's easy enough to calculate the *direct* costs of litigation, but that is only telling part of the story. How many companies have pulled out of the aviation/avionics market because they don't want to take on the liability of building airplane parts? I can tell you story after story of parts manufacturers and service shops who refuse to produce or work on airplane parts because they are afraid of the potential liability. Econ 101

          How thorough were those numbers? The correct numbers need to consider each level of the process and the excess insurance costs as well. Each part manufacturer will carry extra liability insurance (that costs more) and will tack that on to the price of their parts. Each producer of sub-assemblys will buy those more expensive parts and tack on their excess insurance costs. That happens all the way up the chain.

      • It is really a shame what planes cost. As a private pilot stuck renting for the foreseeable future, I've tried to figure out all different ways to afford a plane and just haven't been able to work it into the budget. Even decent used planes go for at least $15k - usually $25k or more.

        • It depends a lot on what you class as a plane. Fixed-wing three-axis microlights can be quite cheap and get very good fuel economy (and some have better specifications than the planes I learned to fly in, although they tend to be in the $40K region new). You might consider renting out a plane to other people - at least you can probably cover hangar charges and maintenance by letting other people fly it when you're not, and maybe pay off some of the capital too.

        Can you clarify that statement? What can the FAA do to allow more free market competition? In fact, the Cessna SkyCrasher isn't an FAA Certified aircraft at all. It's a light sport aircraft, and as such, doesn't need to be certified by the FAA. It's built to a standard that is called ASTM.

    A huge trend in the near future (0-20 years) will be home and distributed engineering (inventing) and manufacturing. People will trade information on technologies, how-to information, plans, and parts to make sophisticated products in their home or workshop.

    This is not to say we're all going to get replicators or nanotech manufacturing like in "The Diamond Age" but the level of sophistication of home built products is going to go way, way up. From small appliances to tools to vehicles to weapons, it'll be possible to make a large number of items in places other than traditional factories, in small quantity and high quality.

    To see this sort of thing emerging, look at efforts like Reprap to make a self replicating 3d prototyping machine (which probably won't be 100% self replicating for a long time, but which is a great starting point for at-home applications of the technology) or home CNC machines like router tables and small CNC machine tools. You can buy a CNC milling machine capable of producing small parts eg. for firearms and small engines for less than $3000 with computer. Once these become widespread part libraries for them will be as available as clip-art. Want a new part for your bicycle? Download the pattern, place the raw material in the machine, and walk away.

    As quality items become harder to find in mass produced outlets, items made at home will take their place. Any item with a niche market will probably be made in these mini manufactoria... there won't be a profit any more in making small quantity items since there'll be tremendous competition from small manufacturers.

    No need to keep an inventory of obscure auto parts on hand (or to pay for storage space or sunk costs in the inventory). Just keep the pattern available and churn out parts as needed. Need a part you don't have a pattern for? Ask someone on the internet to measure their part and make a pattern from it, using the same CNC mill to automate the measurements.

    I like the trend myself... but can you imagine the fit the government will throw when it figures out it can no longer regulate eg. firearms because anyone with a CNC mill can turn one out in a day or two? I can see them at first trying to ban home manufacturing, trying to ban precursor items and materials, then trying to create an overarching government agency to police the whole thing.

    It'll be similar to recording companies figuring out they're no longer needed since anyone can distribute or purchase music on-line without their involvement.

    Likewise I can see large corporate manufacturers of some items begging for a government bail-out because no one wants to buy their mass produced crap any more. Why pay $100 for a cheap wal-mart bike when the CNC machine shop in the next town can produce one with 3x the quality for the same price? Why pay a computer store $35 for a plastic keyboard when you can get a solid brass one with better components made at home?
