In-flight wing failure.
Update: As determined by the manufacturer, the issue with the in-flight wing failure was due to a structural defect. The pilot was fully compensated with a replacement airplane kit and a rebuilt engine at no cost.
20Gs at Mach 1. I’m surprised the wings held on that long
It was nothing like 20g. Say 45mph and 50ft radius of turn: that's under 3g. Weak wing. Pity because it was a nice flight.
@@sideshowbob5237 I'd say Barry was being sarcastic. It was more like 40G's at 1 million MPH.
@@sideshowbob5237 I was talking about scale speed. When have you ever seen someone fly a full scale cub like that?
Yeah but did the Kessel run in less than 12 parsecs.
Agreed. Not if, but when. I know it was expensive but also a clownfest.
It was being flown quite aggressively for the airframe style. But as mentioned, a well built cub will take it even if we all know it really shouldn't be pushed so hard.
War zu erwarten bei dem dem Modell unangepassten Flugstil
Flying it like a fighter jet. It’s a cub man.
You don't fly RCs do you?
@@mercdragons you can tell, he doesn't
Been flying for years. Started when I was 16 and flew rc before that. I fly privately and own 3 of my own aircraft, one of which is a helo. I don’t fly rc that much but I own this exact rc plane and can say for sure they aren’t built to handle this. They aren’t built to the same quality of the real ones. The people putting these things together really don’t care. That was my point. It has nothing to do with the type of plane or my experience, it has to do with the quality of the model. The jets are designed for this stuff, these planes aren’t. Same reason you can break an rc crawler truck by bashing it but if you get a 6s basher designed for that it will handle almost everything you throw at it.
You are welcome to come up and ride along with me, You can point out everything I’m doing wrong
I was thinking the same.
Cameraman had one job
Flight would be great bút the cameraman was horrible! I hope never handles any cameras!
exactly... horrible video. Terrible waste.
So many people saying he was flying to rough and was surprised it was hanging on as long as it did is a joke! That wing should NOT have broke, its hard to tell but it actually kind looks like there was a split second of aileron flutter before the wing failure, I fly my hangar 9 108” cub like crazy and it take everything, that should not have broke like that, there could of also been some hangar damage or improperly glued joints that failed
As Col. Chuck would say,
“That’s a hell of a way to treat a good Airplane.”😅
My 51 inch carbon cub turns on a dime. An amazing plane. In fact I thought it would be too much for me to handle. Now anything I get will be in the 48 in. To 50in. They handle beautifully.
Nice landing.
It's a Super Cub. The real plane isn't designed for that and neither is the model. If the guy flying this had fun and didn't care about the crash...that's awesome!
It's no wonder the wing failed, as it's very, very obvious why it happened. Someone should tell this fella he needs a Extra or Edge if he wants to fly like that.
He wasn't doing anything that airframe should've been able to handle. He didn't do anything that would cause excessive stress like outside loops, high speed snap rolls etc..
@@glenwhatley7366 I totally agree with that observation. There must have been some kind of incorrect construction right at that juncture of the wing to have caused this. A wing should be built strong enough with the original components if done correctly to handle that much stress and much more. At least in my opinon.
Diving with power with that type of wing is a good way to induce control surface flutter which will destroy the airframe.
Yeah, and I’m sure the Chinese builders didn’t do a Finite Element Analysis on the wing design.
@@glenwhatley7366 Yep, not over stressed, just another RTF that was not built by someone who meticulously makes sure that all the joints are glued well, and adds reinforcement in key places such as high stressed areas where the struts join. Given how they brag up carbon with these planes, a small rod or even spar laminated to the rear of the LE should do the job. I don't buy ARF/RTF, and I stress the heck out of my models with no failures.
I have a 1/4 sig cub that never had any issues at all, no matter how it was flown. 1/3 balsa USA cub with a dle111 in it that I've never had a failure on.... horizon is good at producing short term use planes. Almost every ARF I have ever had has been stripped, fixed or strengthened, and recovered. For a plane that expensive, designed for the dle 222, that kind of failure shouldn't happen.
Totally agree with you, arfs are garbage, and extremely expensive, give me a smooth glow four stroke and my 1/4 scale stick built cub any day
RIP to the brave occupants of that doomed plane. Condolences to their tiny spouses and children. We're just losing way too many 3 inch tall pilots these days. The entire sport may be in jeopary if these tragedies continue!
🤣 ... Yeah! Every model I've had has had a dodgy pilot.
The dead give away was watching them both stand in the danger ⚠️ zone while revving up the motor.
There is a reason ya don’t do that, and these guys are plenty old enough to know why. What a bummer, super nice aircraft!
In full size Cubs we fly.
VNE is strictly maintained.
Obviously observed VNE in RC aircraft is not.
Impressed it lasted that long, pilot obviously forgot what he was flying. Lost my first Cub thanks to a warped wing flip on take off, second attempt an unintended loop and hand clap. Hope to have more success with a scale RC boat I'm building now.
I've been flying models and full scale for many years. There were no high stress manuvers that I saw. I doubt anything went above 2 1/2 g's. I agree that this is not an aerobatic plane but the wing should not have broken... It was a bad design or wasn't built correctly... run ups holding the wings has been going on for ever.
Thanks for your comment Joe, you are the first to correctly identify the problem.
Those are beautiful aircraft. To bad you had the wing failure.
@@rudyg720 From 30yrs of flying R/C my best guess is aileron flutter. It will make a wing explode with little pieces falling just like happened here. Flutter can be incredibly hard to predict. It's a product of wing resonance coupling with the aileron not just aileron only issue as is assumed.
Looking frame by frame, the underside wing skin ruptures and the airflow does the rest.
Hot dogging to destruction. Sad to see but we all do that at some stage. There are lessons to be learned... dollars lost to imprudence.
most commenters below do NOT know what they are talking about. generally, a (scale) model airplane is way stronger that its full-sized counterpart.!
No use of throttle in loops over stressing the airframe throughout the flight was lucky that it let go where it did, that could have killed someone!
🥴😟
Well noticed, lots of model pilots don’t reduce throttle just after the top of the loop.
All aircraft have a do not exceed speed
Doing an engine run-up and restraining the aircraft by the wings didn’t help the situation either. Lots of stress on the wing root attachments. Gotta love people who have no clue about physics and material strenght. Btw I’m a certified aircraft mechanic and have flown rc airplanes over 30 years
Yeah I saw the stress bend the wing back a little and its alignment is off. It only takes a tiny amount of misalignment and poof biff crunch. I've left my own craters too so I really can't be too judgmental.
Stuff happens.
A true sportsman laughs it off even if they're crying inside.
Not surprised at all, at the tragedy which transpired. Any sensible pilot with common sense wouldn't subject this type of non-sport aircraft, whether full-scale or not, to such G-forces and expect the aircraft to survive.
Happens right at the end of the right strut. Few turns before I think he damaged the wing. Yikes. What a heart breaker.
The wing didn't fail, the driver broke it!
Those are beautiful aircraft. Too bad you had the wing failure.
Damn, that's an expensive arf.
Lesson learned…. Wow… fly it as it should be. Get an Extra 300 for that kind of flying.
The good news is that you can buy another one just like it. The bad news is that it will probably do the same thing as the first one you bought.
318 there is a single flutter of starboard wing, then it shattered. the flutter itself should not have happened if there was not already some 'invisible' weakness/damage in that wing half.
Wouldn't stand at the leading edge for a power check......... one day the prop will let go.
I'm not surprised , pulling loops like that ,🙄
Absolutely correct! Little or no sign of cutting the throttle back at the top of the loop whatsoever! I don't know who taught him to fly!
The way you are flying it, I am surprised the wings stayed on as long as they did. Hopefully if you fly real planes you don't fly like Maverick all the time. Seems you also put in a very powerful engine, seemingly too big for that model. JMO
Flutter is a possibility.
You shouldn't fly a scale airplane like a 3D plane... That is just my humble opinion.
Sorry for that loss... but if you fly a big plane like that as it was a CURARE or so.... no wonder..... so sad !
I had an great planes electric cub I built did same thing I feel I didn’t over stress it but the wing felt over wise guess the cub wings done like the wing stress
That one stung!
Heh, been there and done that. With R/C, it's tons of fun to pull that stick (In my case, to the point of hearing the monokote flap in the wind!), but sometimes it's just a bit too much. :P I had one .25 sized kit with my repurposed heli motor where the wings failed, pulled the ENTIRE radio kit out with it and as it's last act of hatred, pulled the throttle wide open. So, my airplane turned from an airplane into a nitro/methanol powered VERY angry lawn dart. That thing must have been turning 30,000 RPM before it hit the ground. Full throttle, straight down from many hundreds of feet. But what was most shocking about that was just HOW fast it went from EEEEEEEEEE!!!!!!!!!!!! to nothing. It hit the ground so hard I had to get a shovel to pull the engine out. I rebuilt what was left and flew it again though! Engine needed a new main needle and such and the airplane was probably twice as heavy afterwards, but it flew again! :P I also had a heli that did the same thing. 'Cept in that case, radio failure. That rotorhead was probably 3500 RPM when I said "Watch this!" (Yes, for real. Ugh). I was going to do a full collective climb out to show the explosive performance of that unit. Well, it was explosive alright. The POT in the radio (sensor that tells stick position) failed and the wiper went off the end so if you pushed the stick to the top and applied pressure, it THOUGHT it was suddenly all the way down. That heli hit the ground so hard it was like it was full of dynamite. It was a total write off. Hence my catchphrase of "Crash, thousand bucks.". :/
Drunk pilot's final words to ATC: "Hey man, watch this!"
That pilot put a lot of G's on that wing looked like to me. That wing should have been made of carbon fiber then it would of held together for sure. Isn't that why the full scale Carbon Cub was made,to be lighter and stronger? It's just a 🤔💭
@ 3:19 the cough of carnage, that's what to expect when you throw around a Cessna 150 like a P-51! 😐
H9 should take care of such a failure... IMO a certain design and/or material and/or workmanship problem...
Let it snow let it Snow let it Snow
That was a nice looking plane sad day
Vince Stapleton nailed it........nuff said.
"Waldo...why even I could do an outside loop."
Heartbreaking
H9 reply: 'Obviously he hit a cloaked UFO that couldn't get away fast enough...'
I have seen plenty of RC pilots at the local field who insist on flying scale planes in a fantastic way (fantastic as in fantasy, away from reality). One guy flies a Freewing B2 bomber as if it were a pattern plane (loops, split Ss, Cuban 8s, inverted flight). Another flies a small T-28 as if it were a 3D plane). I see large warbirds that attempt to take off as if they were IMAC planes. Others bank and yank scale EDF jets as if they were hot racing planes, to the point that they flex the wings way too upward, as if about to break.
I don’t know what’s the point of flying planes in a way they were never designed for. This is asking for an eventual structural failure and a crash. Just today there was a pilot who had not flown an EDF jet before and even with assistance, he kept making maneuvers that were over stressing the wing-the wings were flexing upward a lot with the high speed, tight turns he was doing. Pure bank and yank, with no finesse or smoothness.
Absolutely INSANE ! Pilot should be committed for evaluation & observation.
I'm not sure but I think it suffered flutter on the right aileron causing immediate structural failure
Pretty ragged flying, not surprised by the outcome!
there are horses for straddles and horses for saddles i am sure you know what it means now
Awesome pilot. Shiz happens
Maybe not the smoothest flyer but they was nothing ridiculously aggressive about his flying there must have been something underlying setup or quality control issue.
I have freezed the momment of failure time and time again and I only have one question. When your recovered the plane was the prop still in one piece...? Because it looked as though the prop blades split and one of the blades went through the wing...! I am by no means any Dick Tracy but I just found it weird for the wing to have split the way it did because at the time you where almost climbing or geting ready to climb at that point of failure.. And if you freez frame and watch it, there is a black object just to the rear of the tail section and looking at the engine I see only one blade or what looks to be one blade... I know that this accident is not something you would like to revisit again but it sure looks weird.. I pulled this video up while thinking about buying this model and just took interest into the accident as I did not want to invest money into something that would look like this during a flight...
YOU MUST USE GOOD GLUE ON EVERY JOINT IF IN DOUBT GLUE TWICE
I can’t believe people still stand beside a rotating propeller- people who should know better !!
There are no old bold pilots..
*Let the Sunshine in*
The Sun way up high in the sky...
I love super cubs, it is great to see such a large scale cub. Even better seeing a large scale super cub doing acrobatics! Sorry for your loss, that's a beautiful plane
*was
Man...tough bunch. Sorry bout your stick.
I think he was TRYING to kill it.
No Wing Failure...... pilot error.... A Piper Cub isn't design for such stunts.
rip REST IN PIECES
It was only a matter of time flying like that…
Aileron flutter?
Oh man… so agree. This is a gentle flyer, not one meant for hard maneuvers…
Que pena sou piloto de aeromodelo É muito ruim quando acontece isso .
Almost looked like something hit the wing…
I think the right aileron suffered flutter and immediately caused structural failure
His face is like.. What happened? Hahahaha
This is why we cant have nice things😂
Power dive on a cub? Ahh nope. beautiful plane too.
Just wondering WHY anyone would like to fly a J-3 Cub model like that? What was the point? Show how clueless one can be? Even it is possible to install an overkill engine on an airframe like that, it really doesn't mean it is a must. I miss good old times, when we had to build our models from scratch. The idiots would always eventually run out of their models. And the peace would prevail at the RC-field again.
There’s something called inertia that affects all objects, including nice H9 Carbon Cubs. With this ws and these tight turns, like if it was a funfly, and considering that the model is an Almost Ready To Crash, I’m surprised that the video lasted that long.
BTW, the first turn to align the lane for takeoff was incorrect; the pilot did it towards the pits rather than away from them. Safety red flag 🚩
Yeah wow. Can’t even attribute this to a bird strike.
Pattern plane that looked a lot like a Cub.
If that was a arf.that plane was built on glue ordering day
That is what happens when you fly outside the flight envelope. Just as well he hasn't got his hands on the controls full size.
this comment is what happens when you don't know what you are looking at. see my analysis above.
@@daviddavids2884 What aviation experience have you got ?
Well isn't that proof of poor construction or design? And exceeding the design? Too bad we couldn't see the impact or aftereffects of the crash. Bummer dude.
WELL ...NUTS !
Como podréis ver en mi canal, yo vuelo mis propias construcciones... el ultimo diseño que he hecho (Piper Carbon cub 1/3 escala), lo hice pensando en hacer algo de acrobacias, por ello esta bastante mas reforzado que un diseño normal de Balsa U.S.A. por ejemplo...
Pero quien vuela aviones que solo ha ensamblado, no sabe como están construidos...y si se les da un uso inapropiado... normal que se rompa.
Lo lamento, porque ha ninguno de nosotros nos gusta romper un avión
Saludos desde Barcelona.
Show the crash; not the wing shards
Why would this guy buy a cub when he clearly does not know how to fly a cub. He would be much happier with an aerobatic plane.
....at 3:19 "wow. ........"
You can tell a lot about a man by the way he flies his models. 😶
“HAHA!!” - Nelson Muntz
Plane was not being abused! Stupid comments. Something was defective. It's not a glider! It was meant for aerobatics! 40 years rc experience.
Ha ha ha An ARF cub let alone a company like Hangar 9 known for light weight being flown full throttle in a down line with abrupt pull ups. The guy was all over the sky, no semblance of a routine, just banging the sticks around. Ha ha
@MikecamRC Plus literally never blew the wings apart on a model! Nevee seen it happen in person, only youtube.
I would call that an In flight pilot failure...
Used Chinese wood glue?
Like using a prius for a farm truck.
I wonder if these kiddies still play with boats in their
Ain't no 3D plane!
That’s a guy bored with his plane..
Way too fast for that airframe. The wing failed just on the outside of the strut. Completely pilot error. No throttle management
wrong. see my comment above.
@daviddavids2884 we don't need to read your comments. We are experienced pilots that listen to and watched you rip this airframe apart lol. You're delusional
That got em
What did you expect…
OUCH!
Airplane is not designed for those
