RC Giant 120in LA-7 disintegrated in the air crashed 2013 June Chino

[@MisterMeatshield]

Collapsing wings was a genuine issue in real life for La series aircraft in ww2. Good to see this model is historically accurate.

[@itchyvet]

Rubbish, it's bad building by the builder.

[@BobSmith-ow7tw]

Haha

[@DeadAbeVigoda]

That fine line between being lightweight and structurally integral.

[@gshoaf1]

Hate it happened to such a nice looking plane. Beautiful crash though. Rates a 10.

[@kilura1]

POOR la-7. I hope that you built one more

[@Tbonyandsteak]

If Gajin made it, it would have been indestructable.

[@xpoppers9240]

But it would've cost you 129.99 and you can only buy the pack.

[@norskefosvaret2007]

YOU GOT A HOLE IN YOUR LEFT WING

[@possiblyadickhead6653]

Norske Fosvaret yeeeeeeeaaaaaassss

[@TheKRU251]

Ex aircraft engineer. My thoughts were an aileron hinge failure. Such a shame as that aircraft (airplane to US readers) sounded so good.

[@richbran10]

As far as I can see the model was not airworthy at all before take off. During taxy-out the left aileron already hangs down quite a bit. If that is due to play in the linkage, one asks for flutter. It it was for trim needed on a previous flight, it could indicate a problem like a wing structure cracking was already progressing. It should have been investigated and the plane should have been grounded. There is an unacceptable difference in UP elevator during taxy, the left one is 20-30 degrees less UP than the right one. Building and flying large models needs a different mindset than flying a foamy. This was an unnecessary dangerous flight regarding to the safety of bystanders.

[@richbran10]

Scott, nu luckily not, but it could have been if somebody would be killed by it. A few Years ago back here in Europe one comparable large model dove into the public and killed two onlookers. I wonder whether You still "lol" then if they were your relatives. I fly large models as well, and something always can happen, but this is a case in the category of "avoidable crashes".

[@donkboys]

Wow, you are quite an expert, I bet you have never in your modeling career crashed an airplane.

[@jamescureton]

Don Kargo yea...I know....he even had yools measuring degrees through the pc.....that concerns me...what an expert

[@Paiadakine]

You know richbran10 is pointing out a few issues that should be looked into if the root cause of the crash is to be determined. If not, then OK, but don't berate him. It was a spectacular in flight failure and glad no one was hurt.

[@wylierudhman1603]

richbran10 I doubt these items caused the wing to fold

[@davidcurry5306]

Nice model Lavochkin, shame about the snap!

[@nicomeier8098]

Shame to see such a beautifull aircraft crash...... :-(

[@hissingoose]

Gotta watch out for the ghost 88flak gun.

[@MrBioniclefan1]

yeah

[@ScoutSniper3124]

NO PILOT! Well there's your problem!

[@jerrymccrae7202]

Ahahaha.....look at the bright side...the engine ran perfect to the end!!!

[@CONTACTLIGHTTOMMY]

"Hmmmm...did I remember to glue that spar?"

[@airmuseum]

Examination confirmed that the airframe was glassed and insufficient adhesive was missing in critical areas of the wing/spar/rib attach points. Shame.

[@kevinkrska5569]

There needs to be a thorough investigation. Was the transponder turned off? Was it shot down?

[@robcrawford9657]

Lovely scale plane and an even better scale looking crash.all models have an expiry date and his is a great way to go!!!! Thank's for the video.

[@JahBagaI]

Beautiful Lavochin... sad to see it go in like that, bad luck... got another built yet???

[@bliglum]

Looked like classic war footage.

Oh that sucks...... Glad no spectators were injured or worse.

[@j.h.holliday5748]

gmcjetpilot - pretty much said it. However, I ask this: "Did the structure fail in and around the aileron & the servo installation area?" It looks like it in the video. Model planes get 'less forgiving' as size and weight go up; if that was a 3-foot span 1/2 A powered ship, it never would have happened. When we build these larger birds, it is very important to understand the stress factors, & where the high-stress points are located, and be meticulous in our construction. Any sort of "that's good enough" procedure must be avoided. Please do not mis-understand me; I'm not saying this was the case here. Thanks for the posting, I think it's a valuable lesson for all of us who like the 'big' ones. It's a beautifully done model; were you able to salvage & re-build?

[@lovera3878]

Is there anyway of fitting an emergency parachute for when break ups happen. It might help lessen the force when it hits the ground

[@allegory7638]

The NKVD showed up at the builder's house. He's now in a remote camp making balsa planks on a tiny bandsaw.

[@silverdrillpickle7596]

😆🤪

[@professorgarhart3378]

There was a FW 190 just out of frame that took it out!😁

[@Ramiiam]

Beautiful aircraft. Sorry to see it crash.

[@ryanmiller3789]

Do you have anymore footage of this plane prior to this crash?

[@adamtaylor7412]

That's a real extreme shame, it was a beautiful airplane.

[@brex50]

The Ghostly apparition of an FW 190 faintly visible in the background..............

[@gmcjetpilot]

I hate to see it. As a structural engineer of primary aircraft structure, the rules of stress analysis that applies to full sized aircraft, also applies to models. There is no sense of what load factor "Gee's" these models are pulling, since the pilot (RC pilot) is not in the plane. I can only image the little model pilot went Ahaaaaaaaaaaaa. RIP little model pilot.

[@leifvejby8023]

Me too!! Always does a rough calculation of wings and tail surfaces so I know what I have. Or stress the model to the job it has to perform.

[@陳美珠-u1f]

gmcjetpilot 有

[@fhuber7507]

Certain kinds of models have been calculated to exceed 150G. There are G meters easily available to 38 G from Eagletree.com. There are peizo G measuring chips available up to 100 G. Its very easy to exceed the 38 G meter's range. But in that video, there was no sign of a maneuver exceeding 15G (probably none exceeding 9G) I'd suspect a mix of factors caused it to shed parts, primary being inadequate glue and/or structure. Secondary, I would suspect control surface flutter. Flutter can rip an aircraft apart with very little warning.

[@gmcjetpilot]

F Huber I believe it. That is why fighter planes of the future will be pilotless.... the pilot is the weak link now... I take no pleasure in saying that as a pilot... Cheers

[@fhuber7507]

The fighter pilots of the future will fly remotely similar to the Predator drones that were being piloted over Iraq from as far away as Las Vegas. There's an old sci fi story of robots being made by automated factories and eventually they take over, killing mankind off and the robots from each factory fighting the ones from other factories. (and several variations on that theme) We are approaching that level of technology now and Asimov's 3 laws of robotics are NOT part of the programming.

[@foodhomedotcom2716]

I want to see the hobby shop owner's smile when this happens.

[@AllThingsFlightSim]

Wonder if it had been in an accident before and had internal damage to the wing.

[@welshpete12]

I'm so sorry this happened it was a lovely looking model !

[@ovationpdh]

Gota watch that German anti-aircraft fire!

[@blakjack3053]

Unfortunately structural integrity was significantly compromised due to excessive aerodynamic stresses resulting in rapid, and ultimately catastrophic left wing panel disintegration.

[@kamuginkhan]

We can't even see the Me-109 that shot it down.

[@squach6239]

Kamugin Khan It's always the one you don't see!!!!

[@angelisreal]

It's Bf-109

[@kamuginkhan]

The Bayerische Flugzeugwerke (Bf) wasn't the only one to produce the fighter and later in the war the procedure was standardized to name the planes after the designer, Messerschmitt, hence Me-109.

[@angelisreal]

+Kamugin Khan That was the Spanish Air Force that used Me-109 to distinguish between the Nazi era versions, and theirs

[@kamuginkhan]

The Spanish version was the HA-1112 en.wikipedia.org/wiki/Hispano_Aviaci%C3%B3n_HA-1112

[@DrainPipeJoe]

It looked like something hit the wing, a humming bird or a large bug?

[@Mikeishere1st]

Are we certain it wasn't a mid-air with a small bird? It didn't "look" like it was pulling a lot of G's right then?

[@ScaleJetFred]

So sorry to see this! What was the reason? Fred

[@IBANEZfil]

There was a wing overload. Apparently the owner hadn't made the wing strong enough, so basically the wing couldn't hold up and it just broke. Rob

[@ScaleJetFred]

Very sad, all the work to built and finish the model so beautyful! Fred

[@neargaming2057]

The wing couldn't handle the intense drag and manuver

[@jimmyhaley727]

Pilot Errorrrrrrr

[@ihaveone6086]

@Jimmy Haley.... nahh It points to builder and pilot error coupled with other circumstances like maybe rush to get it to flight line. Check comments above (which are true) about control surfaces.... And that failure could be either flutter or G overload.... (60 degree bank equals 2 g load) add the acceleration (increase in airspeed may have induced flutter) in descending turn without reducing power and you got all the ingredients for a disaster.... but I think we can agree on one point..... what ever it was it was EXPENSIVE....

[@erad05]

What a pity for this beautiful plane

[@Stevesmith-yw7cr]

My brother died the exact same way. Scary.

[@RCScaleAirplanes]

Hit by German Flak ... so sad !!!

[@petejulie1000]

Out of respect for my fellow modelers, I have for the last 45 years refrained from occupying the sky at the same time.What ta hell is 5 minutes?

[@Mr.McWatson]

Things that make me cry: 1. destruction of a pretty airplane Though... it might be kind of cool if someone edited in tracers and a fw190 behind it...

[@thomashockin4128]

I have no idea what happened but I see a lot of time and effort gone in a second. Sorry to see...hope it's repairable!!!

[@stevegauth30]

Daaaaaaaaaaang man, that's a real bummer.WAS a sweet looking plane.

[@scottparis6355]

Wow. A lot of these large-scale models seem to need some engineering input for wing spar strength.

[@HotelPapa100]

Didn't look like a particularly high g-load when it failed. So my money is on aileron flutter.

[@Stevesmith-yw7cr]

Could this have been a terrorist attack? My brother died the very exact same way. I saw this video and thought it was the video of my brother dying. This is very scary indeed.

[@peterrumble]

any idea what the cause was?

[@Kalemnos]

You understand why so many pilots left their lives trying new type of planes.

[@tomsawyer9403]

Now THAT is what I call "scale"!

[@alexandervanwyk7669]

Pilot didn't even bail out. Suicide! It shows you that with increasing scale size the modellers will have to apply better engineering skills also. Sorry for your loss. As a child my plains sometimes took almost a year to construct (no standard kits) with often less than 50 seconds air time. Sad indeed.

[@angelisreal]

Ghost Bf-109 came out of nowhere....

[@endwood]

No one to bail out.............pilot less drone that was. Damned lucky that it missed the crowd,Christ these toys are dangerous flown that close to the crowd!

[@bryanglass6701]

Bloodrock D.O.A. comes to mind: "I remember We were flying along And hit something in the air"

[@benmiz9742]

Ahhh man that sucks. So much work put in to a build like that. Looked like a direct hit from a 88 :(

[@jeancarton1611]

thats sad..... i hope you build another!

[@jeancarton1611]

thanks fellow! i already build the same plane from Andersen plans but i enlarged the plans up to 3.26 m span i feel so sorry for your aircraft..it my favorite Russian. Grts Alexander

[@Rocknranchman]

Man that sucks! Too bad you did'nt have an emergency parachute to at least save the rest of the plane. Think I might add one to my Super Decathlon now after seeing this. It could have saved it..."IF"... you could have reached the switch fast enough! Maybe!!

[@robjohnson8522]

gorgeous plane

[@TheJer1963]

Gotta get an F-15. I have seen a real one fly and land with just one wing.

[@silverdrillpickle7596]

Well hell yea!! 🇺🇸

[@Paiadakine]

Sad to see. Sure had a nice sounding engine.

[@tisoy909]

Doin all them show passes, he missed the Hun in the sun!

[@KaffiFlight]

This plane was a safety risk. Imagine that bunch stuff crashing into the people at the airfield.

[@andrewnielsen3178]

Flutter of port aileron. Too fast and aerodynamic unbalanced surfaces. Wing failed at aileron inside edge. As always gravity won after that.

[@robertcornelius3514]

A bad day for the pilot. A good day for Tower Hobbies.

[@Lawiah0]

it's called sheer-web, it go's between the upper and lower spars.

[@sewingissofundotcom]

Seems that no body cares. No response when they saw the plane fell apart and fell to the ground. I like the "heads up, heads up, heads up" video.

[@CJB-]

Next time use more glue or maybe not I love RC crash vids.

[@jefferyrightmire9520]

realistic flak hit

[@goldenscales]

What the hell hit it's wing?

[@basimpsn]

Fly eagle jet makes it?

[@JacobEllinger]

looks like the wing is made of two parts and when it bent the top half was separated from the bottom half and wind got inside of the two peaces and just ripped it apart.

[@ricdwe]

Blame the aviation mechanic for the crash!

[@timn4481]

i read all the speculation on here and have to say that this looks like a structural failure. there was no change in direction immediately before the failure which would cause and accelerated load that could act more on one side than the other, but if the ailerons are proof of the amount of trim required for level flight, then there mustve been asymmetry in the axis of the wings (a warp or twist etc). or the airfoils themselves which would cause variation in the stresses on each side. the failure occurred at the wing root so could have been a flaw in the material, holes for electrics causing section stresses or weakness..anything.. no one here knows for sure and only an investigation "might" find a hint of the issue.

[@itchyvet]

IMHO, Tim I'd say your right. The last plane I built was a turbine powered job with a foam core wing. Instaling the retracts required much head scratching. I saw many turbines rip the under carrage out on landing most of them were inadequately built to handle the stresses. I eventually used a CURTAIN ROD, just behind the front spar and infront of the rear spar of the wing. Spar ran to the outboard rib of the under carrage meaning the wheel assembly was sandwiched between two ribs, double layer which had the rod running thru them. There was no way in hell these wheels were ever going to rip out, nor would the wing break there either. The rod was also used to join the wings together. The plane all up weighed 25 pounds and under heavy G forces held up nicely. In fact still have the thing today.

[@bigpaul5528]

If you watch when the plane is taxiing at first the wing that failed bounces a whole lot more than the right wing. Wondering if something was damaged before it left the ground.

[@DAS-Videos]

The rest of the video would come from China. Because that plane hit so hard that is where you would find it.

[@WannabeMarsanach]

You got a hole in your left wing!

[@Landotter1]

Damn shame... That was a beautiful bird, too...

[@houseofsolomon2440]

'buy & fly'? Pilot didn't seem aware of airframe limits - a sad display.

[@EUK007]

It was an invisible German BF-109 on his tail that hits him.

[@kochj0713]

Put some of that J.B. weld on it, from the mufflers, and it will be good to go...

[@johnjones4825]

I see a load of uncalled for comments here. Ask most balsa builders, they will tell you that models (esp the wings) are generally well over engineered, so I doubt all the bullshit about poor building, or even fatigue.

[@gsm1021]

Some of the ESM ARF kits I have had blew apart just like this plane. The Chinese company's are not using enough glue. Sorry for the loss.

[@europaeuropa3673]

So many crashes on KZbin from structural overloading of the wing or should I say inadequately built wings.

[@GBLynden]

That is why I just bind and fly my planes. I would be sick if that happened to a plane I put a lot of time and effort into building.

[@hairlesshippy]

I agree. Had the big ones buy the bnf's are just more fun because it's at most a couple hundred to fix. Not thousands!!

[@GBLynden]

Exactly! Even a couple hundred isn't fun, but thousands.....I am not that rich lol

[@triplanelover]

my biggest nightmare is having one of my giants coming apart and hitting people standing in the area. Flew a guys big B17 three years ago, just that happened. nobody was hurt , but closecall. Stick with your own stuff and preflight them and annual them for safety. The rest is luck

[@DJRaderz]

Bloody anti craft guns always get you in the end lol . Such a good looking model aircraft shame hope you could salvage something

[@scottfirman]

According to the new FAA rules,any scale model that crashes will have to be investigated like the real thing. The air field shall be shut down until the investigation is done. Fines will be issued resulting in thousands of dollars to the owner operator. Hey they are out to make money one way or another.Good thing it happened before the new rules. J.K. I personally will never buy an older aircraft like that because I know over time the glues tend to dry out and fail. It was more than likely a failure in the wing roots. Balsa gets brittle and weak after a few years. Those planes get flown hard and fast,causing microfractures that spread over time. After a few years of pulling high G turns and wing overs,well thats what happends,complete failure of components. Next thing you know Hobby King will be selling a ultra sound machine you can use for checking the condition of all your planes. As for the FAA...well shit.

[@ZicajosProductions]

+scott firman Great points. Balsa isn't durable forever, _especially_ in faster, more aerobatic plane. One day, as has been observed with some real planes, those micro fractures just give in. However, if this was a new plane, the easiest conclusion is that it simply went beyond a G-limit. :)

[@TheJKAQ]

+scott firman Except the plane was brand new at the time of crash. Just a failure of some type

[@scottfirman]

+Joe N. I wouldnt use it myself. I hate that foaming action. I found wood glue works best for balsa and have used it for years. Most model planes are not expected to have that long of a life anyways are they? I find some on craigslist from time to time. they are usually warped and in terrible shape. storing a balsa plane in an environment like a garage rafter or wet damp basement is cruel. May was well fly it into a tree. Yeah,improperly stored planes get low scores in my book. the motors are usually seized up also. Seems no one knows how to properly store a motor or clean it before not using it in say,10 years. then they try and sell it,thinking its worth a lot. lol.

[@ZicajosProductions]

scott firman :). Some planes are recoverable, some aren't. It just depends. Glad the wood glue works for you, though.

[@itchyvet]

@@TheJKAQ Good point mate. Dunno where RC Hobbyest Extreme came up with his idea, as I didn't see any mention of age in the post. From my personal experience in building LARGE models, I have to say, there was very little Balsa used in their construction. I mainly used lite aircraft ply and spruce ply in stress locations, I used foam wings and experimented with fiberglass coverings, starting with glass cloth, then carbon fiber eventually ending up using the Wife's shower curtains which were the best of all. Place on a glass sheet after ensuring release agent is applied, squeegee the epoxy well into the curtain material, scrap off excess, allow to cure. When dry it's an incredible strong, light, hard sheet which you then glue onto the foam wing. You drop a screw driver onto it from standing height without incurring damage. It's easily painted and never, ever rots or breaks down.

[@SabrinaBraden-n7n]

That's why i gave up large and giant scale and went to electric micro planes.never looked back.

[@kochj0713]

Extreme to keep the means??? I think you could have downsized a few before you go from giant scale to pewee sclale....

[@itchyvet]

Thing is mate, you have to look at it all as a challenge. Try to come to grips with it, build a model and successfully fly it well. Feels darn good to do that. Of course once you've done that, you can try to improve on your building, when you've done that, it's time to move on to another challenge, like multi engines or turbines. Regards the later, your newly gained building skills will be needed for a turbine job.

[@uberkloden]

Chuck Norris would have saved the aircraft.

[@captaincornflakes6384]

Lol just had a sex ed advert XD

[@MikeRoberts1964]

Capt. Murphy claims another one.

[@123jerro]

Yeah looks like he was stressing a lot of Gs in a shallow dive and haulin the mail like that . maybe even a little bit of aileron flutter might have gotten the ball rolling . hard to say
