Show HN: A high performance airplane for the price of a luxury car

92 点作者 carleverett将近 12 年前
The Light Sport Aircraft category was created by the FAA in 2004 with the hopes that it would lead to the first affordable airplanes. By lowering restrictions for LSA’s, it was predicted that planes would be able to sell for around $60,000.<p>9 years later, none of the big players in the industry have been able to accomplish this. Cessna made its Skycatcher, which was supposed to sell for under $100,000. It launched in 2007 at $110,000, and has since increased its price up to $150,000. Several, better attempts at an affordable LSA have been made since then, but decent planes have struggled to find price points under $80,000. A few are sold in the $60-80k range, but these are “bare-bones” airplanes, and the market has shown little demand for planes not equipped with radios, lights, navigation, iPod jacks, etc… even if they are affordable.<p>I co-founded a company that has made an airplane with all these amenities and more for $55k. The design has been around for a few years now and comes from a kit-plane manufacturer in the Czech Republic. It is tiny: 250 pounds empty weight, which is small enough to be classified as an ultralight (although its performance takes it way out of ultralight eligibility). It is very strong, capable of carrying 60 pounds of fuel, a 230 pound pilot, and 30 pounds of baggage. Because it’s so small, the performance specs are competitive with the Cessna Skycatcher on just a 50 hp engine. It is very fuel efficient, getting 60 mpg and flying 575 miles on one tank. Radio, GPS navigation, collision avoidance, synthetic flight, lights, and an emergency locator transmitter all come standard on the plane.<p>I know this isn’t tech news, but I love this website and rarely get to contribute since I’m not a programmer. Here is our website: http://www.skycraftairplanes.com. Please give me your input.

This is truly amazing. This airplane weighs less than one of the most famous and popular gliders, the PW-5 Smyk.<p>I hope one day to be able to buy one of these to go back and forth from work.<p>Any plans for a dual seater version? That would be awesome and would totally destroy the high end coupé cars market

Wow - that really is quite impressive. And I think it is "plenty technical" for Hacker News. After all - hacking isn't just about computers per se. This is some pretty solid hardware hacking.<p>Your "story" is so amazing - half the price of Cessna's attempt at the same thing?!<p>However, Cessna's variant does have a second seat and a fair bit more load capacity.<p>Q1) Could one sacrifice some pounds of baggage for a bigger pilot? I'm currently (sadly) ~240lbs.<p>Q2) Is there a single factor which dominates the huge difference in price? It appears the Cessnas were produced in the US, until they moved production to China - making (apparently) a ~$71k difference in labor cost! But they still are selling for $150k instead of the original target $110k. So is it labor? Materials? Design? Engine? I'm very (hacker) curious!<p>Q3) You mention the market being uninterested in "bare-bones" planes without radios, lights, navigation, iPod jacks etc. But while the "top tier" of those items are certain to be expensive, the "non-aviation grade" version of most of the sensors, GPS, radios etc have plummeted in cost in the years since the LSA category was created. An in-car GPS unit used to be $500+ minimum - now it is &#60; $100 - with a bigger, brighter, higher resolution display, more CPU and map storage memory and fancy 3D navigation stuff to boot! Altimeter sensors are now basically "freebies" integrated into all sorts of consumer electronics. I find it disappointing (though unsurprising) that the aviation market hasn't pushed harder such that these systems are not such a major cost driver. Do you have any insight into why this is? Or have they really dropped in price, and a system which would have formerly added say, $50,000 to an aircraft now adds "merely $10,000?"

Wow - I wonder if it would be possible to practically use this to commute to / from work every day.<p>I live a 5 minute drive from a tiny airport and it would be about a 30 minute flight to Palo Alto...if this was possible it would allow us to live further away....maybe even somewhere where home ownership is possible!

I have a question, which admittedly is based on my experience with paper airplanes. I have noticed that tiny paper airplanes look cool, but are difficult to fly. When I was a kid, I remember making a paper airplane out of a giant piece of butcher paper. I launched it out of my second floor window, expecting it to soar all the way to the street. It rather pathetically pinwheeled to the ground. It seems that, with paper airplanes at least, the most stable designs are in some middle size range.<p>Is this tiny plane less stable than more traditional "small planes" like Cessnas? I love the concept of this plane, but is it actually a good first plane for new pilots?

Well done on getting this far with your product!<p>Does the plane allow for a ballistic parachute to be fitted? Such a light aircraft seems like the ideal candidate for this kind of device, and it would help ameliorate fears about safety in such a (relatively) budget machine.<p>Also, your site seems to be a little slow at the moment. If this makes it to the front page or HN (or <a href="http://reddit.com/r/shutupandtakemymoney" rel="nofollow">http://reddit.com/r/shutupandtakemymoney</a>) it would be a shame for people to find it unresponsive or down - might be worth investing in a faster server, CDN etc...

Awesome. How many pre-orders do you have?

I, myself, started the course of flying long time ago. I left it because the money, it was expensive for a 16 years old guy :(. My favourite planes those days were Piper PA-11 and the motor glider Grob G 109.<p>I had the chance on many other planes and gliders, like the Nimbus 3DM but I&#x27;m impressed with the prices for this plane. It can be really nice starter for those who enjoy flying.

I'll continue to drive a jalopy and spend my money on something like this.<p>This makes regular travel to and from the place I want to be (as opposed to need to be, for an income) a real possibility.<p>P.S. Another person who would be interested in a two-seater. At the same time, it's only fair I note that my own purchase would not be imminent. (Been a rough few years.)

From the perspective of a mechanical engineer, this is amazing. You're squeezing unbelievable performance from such a small engine.<p>Also, a slightly-larger two-seater would be wonderful for transporting girlfriends/wives. Is that anywhere on the horizon?

If a guy building a submarine in his garage is HN worthy then so is this in my book :-)

I don't know anything about planes but as others pointed out, this looks promising. Have you tried reaching out to some media outlets to pick up your story? It is interesting for sure especially considering the price perspective.

Really neat. I don't know a damn thing about airplanes, but good luck. I think it's quite possible that our dream of "flying cars" will end up being (partially) fulfilled by small computer-controlled airplanes.

If a pilot weighs 180 pounds, can you carry another 50 pounds of baggage? Or does weight distribution limit baggage to 30 pounds for everyone?

this is awesome, I really like it. I hold a JAR-PPL(A) and the cost of hiring a simple Cessna 152 is just ridiculous (same goes for buying) - bearing in mind that it's technology from about 30-40 years ago... I am amazed by the operational costs of the SD-1. Just out of interest, what fuel does the engine run on? Avgas, Mogas (never really looked into UL)?

This is awesome! What would be the average cost per-mile to fly this? Considering cost of maintanence, fuel etc.

Isn&#x27;t this the same as the kit plane already available from Spacek (sdplanes.com)

245lb? Finally a plane I can deadlift.<p>Seriously, though, these look really cool.

I like the little plane. Looks really nice :)
