Don't let the "kit" part put you off. It still requires a ton of effort and skill. You aren't getting an Ikea plane in a box, you're getting a bunch of rough cut aluminum and some plans. You still have to trim and debur the parts to their final specifications, align everything, and rivet it together all without damaging things.

Source: currently working on an RV-8 in my garage.

For those interested in what you have to do, here's another builder's blog (not mine) https://www.rv8-hangar.com/latest-progress-2/

The contents of a typical kit: https://www.vansaircraft.com/wp-content/uploads/2018/12/rv-7...


For anyone interested in a very different aircraft that might meet more people's idea of homemade, I'm building a 1930s Pou-du-Ciel from scratch according to plans I translated from French. It's a wood-and-fabric tandem-wing design that was the start of European homebuilt aviation. My build log is at http://pou-du-ciel.net.


That's an awesome project!

For those following, there is an entire range of home-built options out there. The most complete being quickbuild aluminum and steel tube aircraft like the kitfox, followed by aluminum parts kit aircraft like my RV-8 and the Sling from the article, and plans aircraft like the Rutan series, most notably the Long-EZ (now Open-EZ) which can still be built in a time period comparable to the aluminum kits but all you get is some plans. Then on the far end of the spectrum is crazy people like JasonFruit here who have historical and one-off designs and therefore have to do a lot of the engineering work without the huge communities built around the other designs :)


I can see the appeal of the Vans family too — they are some sweet-looking aircraft with excellent performance, and I hear they fly nicer than they look!


Now that is really cool!


And for those that wonder what a more "modern" scratchbuilt plane is like, check out the Cozy Mk IV: https://en.wikipedia.org/wiki/Cozy_MK_IV. Made from fiberglass and foam cut to templates that came with a set of plans (with a handful of pre-fab parts).

The Cozy is a beaut too. I love it when we come out of the woodwork like this!


Using Twitter as a build log is frankly genius. It would have saved hours of work on my website.


I know a couple people who built the Cozy Mk IV. They're sweet airplanes!


I have always wanted to build an RV, but I have a car that's sitting to be remodeled, so I know that I shouldn't undertake the plane. How long have you been working on yours? What's your progress rate?


If the car is taking forever the plane won't go any faster. I'm about a year in with the tail mostly done and waiting on the fuselage to get in (QB wings).

My personal progress rate has been fairly slow since I work full time but others in my situation have gone a lot faster.


I saw this article when it appeared, but was a little disappointed that "homemade" means "built the aircraft ... from a kit manufactured in South Africa by the Airplane Factory". Not to belittle the time, effort and skill involved (both in assembling and flying it), but to me "homemade plane" carried slightly different connotations than "assembled from a kit".

(I'm no expert carpenter, but I have built some pieces of furniture from basic pieces of timber, etc.; I would consider these to be "homemade". I've also assembled flat-packed furniture from places like Ikea or Homebase; I wouldn't refer to those items as "homemade".)


This is still thousands of hours of effort, riveting aluminum, installing avionics, engine, and interior, etc.

IMO, it's much closer to making furniture than assembling flat-packed from Ikea.


To qualify as an "experimental/amateur-built" aircraft (which is the official FAA designation for these planes), the majority (ie > 50%) of the work must be done by amateurs. This means, in particular, that the kit itself can not be more than half the work it would be to build it from raw materials. So, like other people have said, it's not like you're slapping some parts together and you're done.


Same. very click-baity title. I was expecting something more like https://giphy.com/gifs/car-homemade-zVMrf7rqfZcQM and was disappointed, not a really expensive kit-plane. I mean ya thats cool, but this is a shitty headline trying to take advantage of 1st world bias and low expectations for some clicks. I've built kit cars, race bikes from parts and other things and never once called them "home made". When they start banging out the skins on a metal press we can talk about home made...


Not sure it's fair to call a $120K - $140K† kit (not including the cost of having the engine and avionics professionally installed) "homemade", but still an impressive flying achievement for the 17 year old pilots.

https://www.airplanefactory.com/aircraft/sling-4-kit/


Build time is approximately 1300 hours. Even if it is a kit, that is really impressive.


I had the same thought, but if the team of 20 all pitched in equally that's only $7k each. Still not pocket money but it's much more attainable that way. If they got a grant then it could have been even less.


I'm glad he's able to fly a plane but at this point it really feels like we're cheering on the mid upper class for their accomplishments. I want to see some kid from the slums build a real plane from spare junk yard parts. That would be much more impressive to me.


> but at this point it really feels like we're cheering on the mid upper class for their accomplishments.

We are, and there's nothing wrong with that.


There is - the kid's parents having money is not his/her accomplishment.


And we aren't cheering them for buying the kit. Assembling it successfully is significant.


Money doesn't build a plane.


If I could buy my kid an aeroplane I'd feel pretty damn accomplished tyvm.


I was still really impressed by the 12,000km (7,455 mile) trip... until I saw they made 6 stops.

Getting that distance in a little plane would be impressive. Somebody even went around the world, so it can be done. One ends up flying a wing-shaped carbon-fiber fuel tank.


there was a story like that from India somewhere, but can't find it now


The #1 problem with commenting online (including this post) is the nitpicking of semantics. Truly the best way to generate engagement online is to be "wrong".

Congratulations to the pilots and those who assembled the plane, it must've been an amazing ride.


What a good reason to use more precise language!

The real issue is the news outlet who wanted to generate clicks for their story.

We can all agree that "South African teens admissible airplane from kit and fly it" Is a bit less click worthy.

But the real story here is about how manufacturing is about to make another shift now that the places we have been shipping our manufacturing off to have raised their GDP.


In the aviation community, homebuilt = kitplane.


So then replacing homemade to homebuilt is all that needs to be done to make the title more precise!

For reference briandear tells the truth.

https://www.eaa.org/eaa/aircraft-building


To be fair, “homebuilt” or technically “amateur built” is a category defined by the FAA. So homebuilt is the accurate term for this story.

https://www.faa.gov/aircraft/gen_av/ultralights/amateur_buil...


What does the FAA (and their definitions) have to do with a story in the BBC about a South African aircraft kit flown by a South African teenager, written by a journalist living in Cape Town? Those definitions don't even apply to all of North America, let alone Europe, or Africa.


In the largest airplane market in the world (by numbers), the aircraft would be called an E-AB (Experimental-Amateur Built) or colloquially/more commonly "a homebuilt".

It does not seem unreasonable to use the same language when describing that same accomplishment being done elsewhere.


The question was about the validity of the term “homebuilt,” the point is that there is regulatory precedence for such a term. The British use a similar term. https://www.caa.co.uk/General-aviation/Aircraft-ownership-an...

As does South Africa:

http://www.caa.co.za/Airworthiness%20Documents/FAQ%20-%20Ama...

Since HN is an American site, a reference to the FAA is helpful. I didn’t have time to look up regs for Egypt, but the point is that amateur built aircraft is defined by regulation and doesn’t necessarily mean what people want it to mean. In aviation, homebuilt is exactly how people refer to kitplanes.


> The question was about the validity of the term “homebuilt,”.

Ok, and that's fine. But the headline mentions "homemade", not "homebuilt", which in my mind changes the meaning significantly.


I think its important to point out its home assembled, this was a pre-fabbed kit. Not a from ground up designed plane.


I usually see Hacker News praise African youth for building something, no matter how trivial. I wonder what makes this case different from those others.

In any case, good for them.


Perhaps an article without the photo would attract more praise? What do you think?


How feasible (I guess in terms of costs) is it to build a real home-made airplane? I guess the obvious place to start is to reproduce the Kitty Hawk plane with modern (ostensibly lighter and cheaper) materials?


Very! There's a number of aircraf that are plans only. They used to be the main homebuilt aircraft around. Thankfully kit built is the major bulk of homebuilt aircraft today.

If you had $20K it's perfectly possible to build a day only single/twin seat runabout.

http://www.chilton-aircraft.co.uk Plans available free after permission to build from Mrs. Ward.

https://www.pietenpolaircraftcompany.com Plans available for $180. Wood kits with all the wood for specific parts available in the $75-$300 range.


With the plans and a basic toolshop I'd imagine quite straightforward*

* Assuming mechanical ability and a toolshop and not making the engine.

Wright brothers did it from first principles, built the engine and where bike technicians.

Wouldn't be cheap though for the equipment.

People built planes as a hobby pretty much as soon as they were a thing, the internet and overnight shipping would help, be thousands of hours work though.

https://www.popularmechanics.com/flight/how-to/g631/4-amazin...

This one is really impressive https://generalaviationnews.com/2010/12/05/savor-the-experie...

And he has a site here http://www.aerostruk.com/the-plane/


The airframe is relatively straightforward (albeit a lot of work). Trying to make an engine at home from first principles is, for most practical purposes, prohibitive or at least, ill-advised. Even people who do automotive to airplane conversions often run into issues. Innovate on the airframe if you must, but choose a proven aircraft engine.


If anyone is also disappointed that this was assembled from a kit, there's a Youtuber (Peter Sripol) actually making homemade planes: https://www.youtube.com/watch?v=O6sy5bt4D-Y. Would recommend his channel.


Really top quality journalism by the BBC to conveniently redefine the definition of homemade to "pre-made parts and watched over by people who know what to do" in order to get more clicks through 'shocking' headlines.

Don’t blame the students for click bait journalism. They still did something worthwhile with their time and probably learned a lot.


Kids flying VFR from South Africa to Cairo is amazing even if they did it in a Cessna.


You also don't have to understand anything about anything. That's not to take away from what you are doing, but the title completely misrepresents the amount of competence of these (likely spoiled) kids.

Also, what's the total cost (for ALL parts, but without labor)? I looked at their site and it seems to list $30-40k but I don't see the engine included in the part list.


Please don't take HN threads further into flamewar.

We detached this from https://news.ycombinator.com/item?id=20396583.


Wat.

You can go off and just buy the kit if you want to die I guess...

I ended up taking a class on airframe construction from a licensed A&P and probably spent several hundred hours doing research at this point.

Engines can be anywhere from a 10k run-out old Lycoming or a $40k+ brand new IO-540 in a crate.

On the issue of "spoiled kids" there are a bunch of schools in the US that do a similar build project (typically an RV-14 LSA). It's not uncommon for more vocationally oriented high schools.


Thanks for info on costs. I wonder how these compare to Cessnas.


A new Cessna 172 is just north of a quarter million dollars, it seems.

Experimental/amateur-built aircraft are the fastest growing segment of aviation, precisely because it represents a fairly affordable avenue for getting into flying. The prices of certified aircraft have skyrocketed way past what any normal, even reasonably affluent, person can justify.


I mean performance / safety wise.


Ah sorry. Safety-wise EAB has a slightly worse accident record than certified small airplanes, but not much. The majority of the accidents are due to pilot error, so it's not clear the type of aircraft makes a difference there.

Performance-wise, you can get better performing airplanes, with better instrumentation, for far less money as experimentals. This is because they do not have to pass any FAA certifications, so there's much more innovation taking place in the EAB market.

Of course, it's also dependent on the builder and designer doing a good job, so especially second-hand markets can be iffy since all the due diligence for figuring out what you're buying is on you.


Cool, ty


That's an entirely unfair characterization. I've seen many different clubs working on many different kit planes, and they all require high-level capability, attention to minute detail, and very little or no tolerance for a sloppy or partial job. It's true that people can start these projects with no experience, but they sure don't end with no experience. Typically people that see these projects through at any level of involvement become experts in some part of the work by the end.


I am pretty sure a redneck doing custom welding and ECU mapping on a LS1 turbo is much more of a technical accomplishment. Genuinely.


"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."

https://news.ycombinator.com/newsguidelines.html


I had to weld up tooling for the RV-8 and am currently working on a 100% custom CB-550 ECU. The CB has so far been an easier project...

I think you need to check your attitude. Unless you also built a plane in high school, that is?


No, was too busy working a minimum wage job to pay for clothing and save for college. What a productive use of time that was.

Anyway, I stand by my point. Not that I have a workable solution for wealth inequality.
