- Valley Engineering Backyard Flyer legal part 103 ultralight. 2013 model with approx 12 hrs. 40hp big twin 4-stroke engine, hydraulic disc individual wheel brakes. Folds to 26'x7' in less than 5 minutes for storage, or sets up ready to fly in the same time. Culver wood prop and ballistic parachute.
My condolences to you for having to sell . Beautiful little ultra light.
Наверное самый красивый самолет в этой категории. Жаль их больше не выпускают. Отличное видео, кроме того.
Bonnie max, there are elongated loops welded to each bolt head and a bungee fastened between each pair of bolts making it impossible for them to rotate. There is also the fifth bolt that is the pivot pin. Again, very clever and effective design.
It's so awesome this plane has a cantilevered wing!
I was disappointed that we had to sell it, it is a very clever little airplane. The music is by a very good friend that plays in my band. Thank you for your kind comment, I'll tell her you enjoyed it.
love the sound of a v-twin, almost sounds like a Harley. made by generac or more recently kohler EFI engines, 38 hp to 45 hp after mods at 90 pounds. kick ass on crappy 2 stroke
Back when I was riding motorcycles if I ever got behind one of those two cycle Kawasaki rice burners I would develop a headache from the fumes. Give me a good old for stroke any day instead of one of those weed Wacker engines.
The sound this engine makes, nothing like of the twin sound.
Great demo video.. Thanks for posting.
Super! loved the airplane
Welds not fused right welder to low could be set that bit higher just a point but the rest looks really good .
Beautiful music...goes well with the freedom of flight.
Beautiful airplane. love it.
Hey bud! I would put some type of bushing on your aileron swivel tube joints.
I see a lot of sloppiness.
Vibration will wear the material and cause stress cracks and catastrophic results.
I think a new one is around $25000 if you're willing to wait. We sold ours for $17500, what we paid for it.
I enjoyed this video.
Very easy job I liked
I just found out about this little plane and when I inquired with "Culver" props about the cost and availability they said that it's no longer available because they've stopped making it.
When sorting your wing, you should start all four bolts before you tighten any of them down.
Logan Steele - That's why they put a volume control on your computer, maybe you can find somebody to show you how to use it.
The reason we do not turn the volume off before playing a video is that sometimes there is important information in the audio track, perhaps you could get someone to explain that to you slowly.
Na too old. 😊
Шикарно и грамотно!
very nice model and is it possible to get the blueprints of the model for its construction? Thank you
nice..
How are you still making the backyard flyer
Very nice
amigo felicitaciones por esa modificación al tema alar que sale de lo tradicional me enorgullece ver un talento como el que tu tienes , también soy amante de las alas me gustaría saber si tu tienes los planos estructurales y si me puedes enviar algún documento para copiar y fabricar esa aeronave y a la vez cumplir con el sueño de un ulm propio tengo un motor rotax 503 y me gustaría realizar el proyecto con la estructura de tu aeronave saludos desde el fin del mundo.. osea Chile el ultimo pais de latinoamerica
Is there a fire extinguisher aboard?
I watched another video that said they use a gallon an hr, but I never heard what the flight speed was can you tell me.
63 mph / 55 kts
Good
How do they handle in windy conditions, max crosswind component ?.
It is the self-made plane or set?
sad to see this went out of production, nice air frame work and welding, a lost talent
Still available as far as I know.
@@LuggageStardate Sad News. Thank You for the reply.
Qual a bitola do tubo e qual o tamanho da asa?
Under 10000$ could be built that kind of airplane? How long time?
What happened to Gene Smith?
He passed away in 2016. They no longer make them or sell plans, too bad cause I think they would sell a lot of them😢. They only produced about 20 craft in total
How to make plan wing(which type of material use it) tell me sir
Glad you were able to sell it. LOVED the VERY calming background music, what was it?
The best of luck and high regards!

This argument about "TRIANGULATION" seems a bit silly to me. There are many parts of Boeings, Airbus, etc that are not "triangulated" for practical reasons. You just have to compensate with materials/thickness etc to make it all work. Not rocket science.
Very nice plane

Hello! I am writing to you from the Republic of Belarus. Please tell me what metal is your plane made of !?
I no longer own this airplane, but I can tell you it is constructed primarily out of welded aluminum tubing.
So what CC Motor was it? 40hp at what Rpm? What did it Weigh?
The engine was a “Big Twin” Generac conversion by Culver Props. All of the specs are on their website. Was a great running engine.
PRICY....must be all the weld time they put into it...wonder how much that 4stroke cost...maybe more than a rotax?...maybe more reliable thank a 2stroke?...
The plane starts at $23000 new. Very expensive for a part 103. That 4 stroke is not cheap but it's realiable and has a great sound
صناعه جميله جدا إعجابي في هذه طائره
👍
has plane sold?
How much do you sell for
I can afford 3, see ya in the spring '16
do you still have it?
was this one sold? and for how much?
Sorry, just saw your question. Yes we sold it for $17500 usd
Some of those welds look pretty rough.
the welds do look rough. I saw the designer/manufacturer showing this plane in USA and was appalled welds that, when I was welding back in 1980s, would have seen me sacked. Cocky shit was how it was termed then.
Plane is tentatively sold pending final payment
How much 25.000 ?
Boa tarde!
Price and contact information would be nice to have.
i need all air craft parts plz help me my no 9997893847

Sorry vinny max, darned auto correct!

Are you available for questions? I live in Kearney. Thanks. Gregg
They cost $29,000 base, all come with BRS,
They jacked price up big time, if u can weld that’s where they get u now, it’s a shame how these companies r taking advantage of people’s money! And truthfully that’s what ruins sport, it’s called greed, this man sold his at what he payed for it because he is obviously a great person 👍🏼
Ya well you get your ass down there in Rolla and weld one up if you think there so easy. A man has to make a living!!!
@@countryflyer4536 u totally missed the point! That’s what people do when they hear what they want! FYI everything AVIATION is ripoff, why should the same engine cost double because it’s for a airplane? Etc
I wouldn't fly an airplane with wings attached by 4 screws hand tight (upside down). Stress, vibration, and gravity loosen these screws in 10 minutes of flying.
the wing attach bolts are "safety wired" in the tight position by stretching a bungee cord from one bolt to the other thus preventing the bolt from backing or due to vibration etc. You did make a his point though and I wonder how long he flew it without the bungee before that realization hit him.
He DID use the bungee cords, he just didn't show it.
Then explain why there have been no in-flight failures of this design. You don't want to fly it, then don't.
You dumb.
$17,500 FOB Lexington, Nebraskascottsarnes@hotmail.com for info
annoying ass music.
Yes, scottsarnes@hotmail to contact me

I would not trust those welds ahaahah
The "Engineering" in Valley Engineering is pure wishful thinking. They appear to have no clue about structures of any kind or stress analysis. I wouldn't buy a lawnchair from them. Having seen the workmanship on a typical Backyard Flyer personally and close up. I would never strap myself into one of the "aircraft". But each to their own.
+PDZ1122 Sir, I would appreciate a comparison of your credentials to Gene Smith's ......as a retired airframe and powerplant (A/P) mechanic - I am familiar with Mr. Smith and his engineering and flight background ...........I find your criticism to be wholly unjustified , both from a mechanical and engineering point of view.........as to workmanship - it is equal to, or exceeds, all F.A.A. requirements for this type of Aircraft...........JRW
+unclejack123 An A & P is a mechanic. A mechanic has no obligation to know anything about aircraft design or stress analysis. "Workmanship exceeds FAA requirements" ?? FAA Part 103 specifies design parameters and flight limitations - there is nothing in the FAA requirements about workmanship or structures at all. It looked terrible to me and I am also a welder certified to weld aircraft structures. Also 6061 alloy should not be welded in a structural airframe. In general terms the FAA does not consider this good practice. (FAA43.13) Aircraft are not bass boats.
Take a look at the fuselage frame of this aircraft is side view and you'll see that there areas areas that statically indeterminate, or in layman's terms, they are not triangulated. Which is why you'll see tubes and welded joints stressed in bending rather than pure compression and tension, like any properly designed framework. These frames will bend and crack given enough flight hours. There have already been fuselage failures during taxying.
+PDZ1122 He holds a mechanical engineering degree also. So he has a mechanical engineering degree, he was a airplane mechanic, and has over 24 years of being a crop dusting pilot.... and he designed this for him to fly because he can no longer pass a physical, this plane has earned high reviews. BTW please state where you earned your mechanical or aeronautical degree from, where your a&p education came from, and how many years of commercial flying you have...just curious!
Like I said - each to their own. I taught myself enough about aeronautical engineering over the last 35 years to know bad design when I see it. Or so my friends (who have spent decades in the aeronautical engineering field) tell me. I'm not the only one who shudders when they see this aircraft. And give me a break - a mechanic is not an engineer. There is no requirement for a mechanic to understand stress analysis. Most don't even know the meaning of the phrase. Neither do crop duster or airline pilots. Or youtube commenters, like yourself. And what the hell does flying a cropduster or any other airplane teach you about stress analysis and structural design?? You sit in one so you know how to design one?
It's a bad design, badly executed - I saw those welds first hand and they were awful looking things.
He is a mechanic....AND....a mechanical engineer...AND...pilot! So over and over again he is not just a mechanic! On one of the other videos where he is interviewed about this plane he talks about the stress loads and why it was built this way. He also talks about his Mechanical Engineering Degree. Please stop comparing this $20K plane to a leer jet, it is an ultralight. Please also check out the reviews on this plane by people who have flown it! He didn't teach himself engineering! He actually went to college for that....just saying.
Good
