- Hangar 9 CubCrafters Carbon Cub FX-3 100-200cc ARF, 165 crashed. Was he flying too slow downwind, and the elevator flutter - was ineffective, and down she went?
Interesting comments here. Having flown RC off and on for 47 years, my two cents is that if he could pull off a halfway decent knife-edge, then he was skillful enough to pilot a high-wing, buoyant, stable aircraft like a carbon cub. It appeared to me to be some kind of radio glitch or perhaps a servo tray coming loose, as there was a simultaneous engine hiccup and down elevator spasm (maybe the engine misfired due to negative Gs). It was most definitely not a stall.
I agree 100%, been flying since the 1960s
Definitely not a stall
But maybe confused and made an up elevator rather than down.
It went in hard on a minor downline. Look like an elevator servo failure to me. Didn't see any pilot error on that
Then why was the throttle on full blast when it happened?
If you think it was too slow on a downwind then you need help
😂 true that!
Flutter, servo failure or pushrod failure. My side hurts from laughing! sorry.
100% pilot error.
I thought the same thing 😂
yes, exactly my thoughts 😅👍
elevator flutter or maybe just elevator control/limnage failure in my opinion
5:26 he doesn't look like he took it very seriously, so should many of you guys. Part of the hobby is having fun, not having a "know it all" busting your blls around.
The sound of the engine skidding down the runway cracked me up.
Nothing funny about that mate unless you actually don’t fly rc planes and just get some weird kick watching folks crash them
@@andypc14 I have a whole house full of em “mate”. Owning and flying RC planes is like owning a car chasing dog. You don’t want to get too attached to them. They might be gone in a blink.
The first landing was super sketchy. To slow on the downwind? That makes no sense. He was in a dive. The elevator flutter is consistent with digital servo flutter from when your right thumb slips off the stick. The guy is a sketchy flier. Too much money not enough time and skill on that plane.
And Camera Crew needs to switch to decaf 👍
Exactly. This was a perfect example of more money then skill.
Very well formulated. Glad it happened in the confinement of an airfield w/o endangering anybody. And overall competencies shown in flying up to the discrepancy leading to impact was already not matching the size of the model and needed mastering…
Bingo!
Exactly! Evident at start he was over his head
Wow man, that’s a lot of hard work smashed up my condolence to the owner
The more expensive and bigger they get the more checks you do... the whole thing is approaching the full size protocol.
Remember this - The difference between a model and "real" is the "real" aircraft is designed to carry people. A model is not. However, that thing would easily haul a cat or small dog :)
And, the bigger they are, the more things you don't do - like trying to zoom the runway at high speed.
@@christopherknee5756 There is nothing wrong with that if its built correctly
@@christopherknee5756 you must fly patterns all day with a 1983 Avistar, My 120cc Beast get abused to death at full throttle. This guy seems to be a pretty shitty pilot judging especially by that first landing.
The nose still wanted to keep going.."what ground?" Dang, sorry to see such a sweet bird de-feathered like that!
Definitely felt that, ouch, I'm sorry that happened..
That was hilarious.
The whole horizontal stabilizer looked to flutter until the slow motion showed just both elevators. So that makes me think it was the pilot. Maybe his thumb slipped off the stick or maybe he just messed up.
If your thumbs slip it shouldn't take THAT long to recover... had to be a structural failure of some sorts
@@ShockeWulf190 What are you talking about? The flutter was consistent of digital servo flutter when you slip on the sticks. He was going way to fast to recover if he slipped off the right stick. He flew it to the ground. Controlled crash pilot error. Their excuse was too slow on the down wind. At that speed heading toward the ground. If your right thumb slips you are not going to recover. The guy is a sketchy flier. Too much money not enough skill
I agree. He was all over the place on the ground, grabbing radio from eachother like they were nervous little kids. Was trying to fly it like a jet, not a stol plane. Lack of experience and knowledge is the only issue here. !00% pilot error.
Looks like they are feeling it... all the way to the dumpster
True Mayhem Park style! Gotta love it!!
Looks like flutter on the elevator
Looked like more throw than flutter. Flutter usually happens so rapidly the control surface is destroyed. Looks possibly like the linkage let go, or control horn failed.
Flutter is a rapid vibration of the surface, that was an up and down movement repeated three times.
Called a radio lockout. Listen to the "hit" on the throttle servo a second before the elevator pitched down. Easy to see and hear with the eyes and ears!!
On a large aircraft I'm pretty sure you'd hear the flutter if it was present, but he was well below the speed I'd expect flutter. The prior flight had a fast flyby without any issue.
@@johnnichol9412 For sure, and the elevators moving appeared faster than the sticks could be moved to make that happen.
I see it as he was trying to get low, or land, and missed. Been flying for years and NEVER lost a plane from "radio failure". If your flying a plane of that caliber, your not using FRSky, your using the best, so how does it failsafe at 100 feet?? Stop using "equipment failure" as an excuse for bad piloting!!!!!!! He was all over the place on the ground, and in the air.
@@ChainsawFPV FRSKY is one of the best systems in the market now days. I fly Frsky on 3 giant scale planes and have never had a problem, can’t say the same why I was on JR or Spektrum
@@crgonzalez08 Tracer and ELRS are the only Rx systems I trust. FRSky, FlySky and Spectrum are nothing but problems.. There is a constant supply of videos of people having issues on them. Never once have I seen a video on someone losing a plane on ELRS or TBS.
@@crgonzalez08 man people have no idea how good frsky is now...
@@crgonzalez08 I had a FrSky X9E and had some unexplained problems during flight what seems to be radio interferences. After a long time i found some hints on the net that the problems may be caused by the connectors of the gimbals. So I opened up my X9E transmitter while in operation. As soon as I just touched the Connectors some Servos go crazy. So it was clearly a fault of that connectors. The easy solution was just to kick out that connectors and to solder the wires directly to the PCB. No more problems since than! So even a good transmitter may have some problems!
Not taking any sides here. But it very well could have been his receiver pack wasn't fully charged. Especially if it was a lipo. These small overlooks can have drastic consequences. 🤷
Radio failure. Engine was intermittently failsafeing right before impact
If there was a gyro inside, there ist the reason.
to much gain brings flutter on higher speeds. Just easy as this
Bull…. That was pilot error all day!
Gyro would have likely caused a higher frequency of oscillations but could have been the cause. However if you listen to the sound carefully you can hear a couple changes in RPM which suggest an intermttent failsafe. These rpm changes correspond with the pitch oscillations. Looks like he was flying jeti so it would have logged any radio issues. Hopefully he lets us know the true cause of the accident as im sure many jeti users like myself would be very interested in seeing if it was a radio issue
I think not.
The guy was a horrible pilot from the second the engine started.
That was a nice looking plane......WAS.......DARN !
I have a FLAT wing cub I built and flew the PANTS off it, it lies unflown now, but I will tell you knife edge no problems, I think he lost the elevator servo, I fly at this field too, Markham Park. Beautiful site. Sorry to see this loss of such a nice bird.
Pilot error all the way - - plenty fast enough for some tailwind had the plane been properly trimmed - - the plane never appeared to be in proper trim from the git go and it showed right as he crashed, watch all of the flight, it was flying too nose heavy, and or in need of up elevator trim (at the very least), one can see the corrections the pilot's making, the plane was not behaving very well at all and I wondered about the flaps being deployed most all of the time, ya can't trim with the flaps down - - low altitude passes with a plane that's obviously flying in need of trim were a really bad idea anyway and stuck me as unnecessary showing off of a plane that flying pretty damn sucky regardless of what the wind was doing although obviously one shouldn't be doing a maiden of a craft like that in bad wind conditions - gawd, nice save on the 1st landing but in reality, that sucked too and now he's making what turned out to be the last low pass in downwind, one can see the attitude of the plane, the nose heavy thing burned him, it's tough to f around and keep up with bad trim and yes, burn him it did. He was barely keeping up with the plane to begin with - all that with 200cc plane, very dangerous, I'd expect more competency with a group of guys that are obviously flying hi-end aircraft - good example of a bad example - shitty flying decisions too, from the start to final end. Shame on the pilot - flying like that hurts our hobby.
I agree with you the attitude in the air looked nose down the whole time .The flying speed was way too high. I am sure there was n cg problem .
@@PieterErasmus-bm3ms geeze, I just reread my original comment - I guess the video or the description or something must have struck a nerve at the time - I obviously went a bit overboard with my rant - sorry to RC Chaser that I took it so far - anyway, thanks for your commenting reply and I agree with you as well - - - happy flying Pieter!
Definitely not a stall. There's a very brief but noticeable pitch oscillation beginning at 5:15 or so, which could have been flutter, though the frequency was extremely low. Usually, control surface flutter is audible, even over the engine noise, but the force it applies to the control horns, linkages and servo itself, even for just a moment, is incredible. It could very easily have rendered the elevator no longer under pilot command, even with everything still properly connected. I think the throttle up right before impact may have been the pilot trying to add power and pull up, both fairly instinctive reactions. A radio glitch could manifest this way too, but that's pretty rare these days. Either way, sad loss.
Ouch! That was painful to watch! 😱 Sorry for your loss... The RC Gods claimed your plane as a sacrifice. You became another victim of the dark side of our hobby... 😱
Thanks for sharing!... Have a great day. Greetings from Douglas, Arizona 🌵🌵👍🏾😊🇵🇷
I flew my P51 today, 2 very scary and fast maiden flights, landings were bounced but survived.
Lord I remember a newbie turning on his radio next to me my Chipmunk dived straight in. Looked very familiar.
From the sound, it was running too rich. The dive caused the engine to get a little more fuel than it could burn due to the richness (lack to air to fuel to ration). When the engine stared to lose its efficiency it pulled enough power from the servos to disrupt them causing the accident.
I sure am glad that I went with that extended warranty !
Sorry to see that Regardless as to skill vrs plane, money vrs skill. (and so on)
I said to myself I was not going to speculate in comments,. but...
The approach seemed too hot and too aggressive of a descent for any kind of thought for a landing.
Also the barn door flaps down made me cringe,. I thought certainly we would see a tip stall or wing drop.
But he kept enough power in that, that didn't happen.
If I was going to say,.. it looked like thumbs goofing up or thumbs still learning.
The flight in general looked like a new pilot to me, that should not have been turned loose on a plane that nice.
Starting with the 1st. taxi and then 6 foot take off. and the 1st landing was almost a crash.... my gut says the plane was nose heavy.
That mixed with, be it pilot error or equipment error, spelled disaster at any rate.
Sad to see such a nice bird returned to kit form.
The guy has already taken enough beating losing this plane,
Remember we all have been there and may be there again.
Cheers.
The main cause is flying it like a 1970's piped .60 pattern plane. Cub's don't make high speed passes.
thats right
I have a FLAT wing cub, it is areobatic for sure, I think he lost the elevator servo
This model has dual elevator servos.@@hardmachine
Yardsale!! Sorry for your loss...😢
That will fit in the car a lot easier !
I would say 100% radio issue, cutting in and out. The oscillations along with engine cutting in and out are like the link going in and out of failsafe.
Had something similar when the spark plug cap came loose and did the same thing but luckily it was on the ground
Man I tell ya. I'm seeing a lot of nice birds crashing due to brown outs. I thought this new technology was supposed to be bulletproof. Makes me want my old Hitech and Futaba stuff back lol.
Wow! .....the ground just came up and got that thing! .....i suspect massive servo power loading on that RX power buss. On my large models i use a UBEC in parallel with ESC RX power, i beef up the RX power rails and i got a 10,000uf 25V capacitor across the RX power rail.
how do you beef up rx power rails ?
@poochies0316 One way i've used is to carefully run solder across all the positive (center pins) and also the negative pins, thus creating two rails that can handle greater current. I use heavier gauge wire to connect these to a UBEC or a dedicated RX LiFe battery. I may also use a 10000uf 25V capacitor at this point. Long servo lead runs like aileron and elevator I do with heavy duty servo extensions. I may also use a heavy duty "Y" lead out at those servos and plug 4700uf or 10000uf caps out at those points to buffer current demand at those servos to mitigate voltage drops at those points during moments of high current demands. I have this presently on my Bergen Gasser and Turbine helicopters, my 120mm EDF Ultra Viper jet and my new T-28 Trojan.
@@cletusberkeley9441 interesting thx I always wondered how much can those little pins and sockets on plug ends handle current wise thx for the tip
looked like a complete glitch for some reason. note the engine slowed down then picked up again in conjuction with the elevator! what a shame!
I feel for you man. I think that elevator locked up.
Aerodynamic loads on the elevator were overpowering the servo. Or a servo failure. It was a slow up and down movement and definitely not elevator flutter.
I played it back in slow mo and you can see the elevator moving up and down ...i`d say radio !!!!!!
Radio "lockout", "hit", as plain as day!!
Looks like it went off the air (failsafe). Notice the engine change note too.
Dammit that sucks. So sorry for your loss bro I saw that elevator fluttered. $10,000 plane bro. I am sorry to hear that bro. It’s part of the hobby man. Shit happens to everybody it happens to us all man. I’ve been there
Ya bro….dont bro him if you don’t know him
@ yo I saw his video last month. I feel bad for him. He gonna get another one. The elevator got fluttered.
flutter does not happen at slow speeds flutter is a problem you encounter at vne and above; there just was not enough elevator authority and it becomes a problem of energy dissipation and inertia. the elevator did not provided enough force to change the attitude; probably elevator failed outright(servo or linkage) or the inertia of the dive was too large for the force produced by elevator.
Ah damn! So sorry to see such beautiful model destroyed. Seems like elevator failed somehow.
Nope!
@@scotabot7826 You said No, the care to provide what was the cause then?
The pilot flew the plane beyond the limits of the electronics. Elevator servo drew too much power and starved power from the other servos - hence why the engine was intermittently glitching out. I don't think it's the radio or elevator's fault. Pilot flew too fast on a plane meant to be flown slowly.
Any large scale radio install should have power distribution systems capable of producing more than any modern servo would normally draw and they also isolate each servo so any short will only effect that individual channel. They also run off of multiple batteries and receivers that can be isolated/ignored when a fault is detected. This is common practice now, with some radio manufacturers even offering power distribution and redundant features in their flagship receiver packages.
My largest sailplane uses not only two main radio batteries and four independent signal sources/receivers, but I also run all non-critical servo functions through a completely separate power distribution system running on it's own power source. If a retract servo or brake servo locks up and completely drains the secondary power source, my flight controls aren't effected in the least.
If you are flying something this big without multiple redundancies in your radio set up, you are not only a fool, but are endangering all those around you when your large scale model is powered up and/or flying.
Nope Sorry. Don't try and make something that's so easily obvious, in to something difficult!!
outch, sorryfor your loss, looks to be a locked elevator servo
You should not fly a Piper so fast.
That had nothing to do with the crash.
@@TheBigO-k6gyes it did. Cubs are not meant to fly 150plus scale speed. Total waste of a plane.
Seems to be the failsafe kicked in at the last moment... Sorry for the loss...
This guy definitely felt it
Underpowered. Tight slow bank means loss of altitude and airflow. More throttle power would have saved it. Poor Mr pink pants.
"Pink pants" 😂😂😂😂😂 stud
Why TF does a cub that size have 200 CC in it? That's overpowered even for a 3D plane. Then you take this clearly incorrect plane and do a full ,power drive towards the ground. This was 100% user error.
All the signs of pushrod (bending) overload. Always ‘pull’ for up elevator (horn on top) never ‘push’ (horn on underside). I also learned the hard way.
Like butter!
You guys got it all wrong, it’s obvious that the ground was to high.
Bank balance seems to exceed setup and flying skills. I've seen it many times over my 50+ years model flying experience. Only yesterday, a loads-a-money newby did a horrible hand launch of their fancy new EDF jet. Boom, into the ground. Undeterred, they will buy another one for next week! Only passed their proficiency test (BMFA A certificate) a couple of weeks ago and already want to go for their B certificate. God save us.
I hope I'm wrong and it was a dodgy servo or other electronic equipment failure. It's very rare these days, though.
If you don't want keyboard post-mortems, then don't post 😉
It's good to hear from someone who has never crashed a plane.
@@johnnichol9412 Every field has the crusty old farts sitting up under the clubhouse & who nobody has ever seen fly anything, judging everybody else. Clearly Mr. Hutson is "that guy"
that'll buff right out man
Fresnel zone. I’d be checking into it if I were flying expensive RC planes in that area.
I dinged up one rc plane at our local fly field coming in for a landing. Many thoughts and checks performed. It never happened again with that plane. Fixed and flew it several more times without issue.
Went back to that field again with another plane. Flew around fine made several flights. Came in on a similar approach this time with a larger Aero Works Bravata. I could clearly tell that something was knocking my radio out of sync.
Another club member informed me that I was making a mistake flying in with that approach angle. Somewhere at around 30 to 35 degrees. He suggested several expensive options or just standing in a different location if I was going to take that landing approach. He also explained that having my antenna on my receiver extended straight out was not a good idea in these conditions. Fold it up 90 degrees.
To me it looked like signal loss with the simultaneous engine surge and pitch oscillation just before the carnage. If I've learned one thing, whether it's a $5 or a $10,000 aircraft, they all seem to have an expiration date!
there were a number of places in flight where altitude contro seemed to be an issue
This thing has a larger engine than a motorcycle I'm looking at.... lol, I'll say it hurt me seeing him crash that but what caused him
to lose control right there? Was there a burst of wind or something else I couldn't see? Anyhoo, I'm starting to like these birds.
Radio failure or pilot error
if you feel it....go PICK IT UP
Everyone in here opining about the cause of the crash and I’m over here just hoping the camera person gets some treatment for the epilepsy they appear to be suffering from.
😂- "Elevator Flutter"?
How about the flutter from all the LSD the camera person took before "filming"
I would never smile right after that!
Even if it’s just a hobby, one small mistake or a material defect, and everything is ruined. No, no, no. Only model airplanes with a max limit of $500! Anything beyond that is pure madness.
Radio…. Throttle and elevator glitching. Sorry to see that happen .
He might have manually reduced the throttle to stop the elevator flutter
Exactly!! So simple, yet you have people on here writting thesis papers as to what happened. Man. it's so funny. These people kill me!!
Cheap servos on the elevators?
Nope!
@@scotabot7826 what servos were they?
My money is on improper trim , all through the beginning in the go arounds his tail was too high, when he made his final descent to drop down the excess trim combined to dive the plane steeper. Right before the plane dives the tail( elevator) wavers up then down driving the plane down steeper into the ground.
Breaks my heart :(
Neither - that guy is drunk. Forgot to close the door; can't taxi straight; can't keep any consistent controls or throttle in the air; and only by the grace of God he got a second chance to crash it after the quality of the first landing attempt. I'm going with alcohol goggles.
No feel, no chase on that one!
Elevator failure if he was changing throttle. Seems too close for signal loss. Possible low voltage to rx.
A shame, it was a treat to watch. almost surely elevator failure. May need a bit more stiffening around horn area.
This bloke must be super rich or dumb, smiling after the crash like it was a bit of fun !
I thought the smiling response and indeed the good attitude of all of them was excellent, like men
Smile to keep from crying. You know that cut him deep.
@@clintshearer3027 Yes, very sad regardless😒
Obviously the elevator fluttered. But I don't think he was going fast enough for an aerodynamic flutter. You could also hear the engine surge. I think radio problem caused elevator to flutter and engine to surge and hence crash.
Its now a puzzle that can be glued back together. Meanwhile get a Tower 40 Trainer and get some practice.
Sorry to see that bro, real sorry for you!!! But it can happen.
Elevator flutter in that dive. Elevator linkage and or hinges not solid enough to handle the speed.
Radio lock out. Hear the throttle? Lost signal.
That’s a possibility. If so then he had his failsafe all messed up.
Lockouts do tend to happen more often from head on flying if no rx is mounted high or low enough
@@thatairplaneguy it’s 100% lockout. Big problem out there for many many years. They see engine power like it was supposed to. It came back for a second and cut it again.
Looks more like when he got it really cooking the elevator fluttered...could also be if he had a gyro the gains were too high and the speed exposed that so it oscillated. I think he cut the throttle himself. Either way the elevator fluttered for sure, and saying it was 100% anything is a stretch without being there. We're all guessing. Lol.
@@ModelAV8RChannel that’s my home flying field. I’ve got people who were there and problems with Jeti lately. I will bet on it being a lock out. You can hear and see it. No way he pulled throttle and back on that quickly. Trust me when I say radio lock outs are a daily issue there. All pretty much on the right side of the field (where it locked out). That was not flutter that was glitching.
@@westhobbiesrc8051 Interesting it would only affect the elevator then? I wouldn't think the elevator on that plane would react that fast. Sure did look like flutter but maybe not. Did he have telemetry? Anyway, lock out or whatever it was it sucks regardless...nice plane. I feel for him.
This plane was destined for a date with mother earth!
Only one thing lacking here, unfortunately.... proper flying skills, and that' all there is to it.
It did look as though he pushed the elevator stick then pulled it as he realised he his mistake, I have seen it happen with people that are not regular fliers or still learning as lots of beginners think you push the stick for up and pull for down.
Here’s my two cents looks like classic elevator flutter. Check your servos and linkages,I think you’ll find stripped gears. When flying giant scale airplanes you’re only as good as your weakest link and it’s good advice to fly it like a scale airplane.
got some glueing to do.
Only $2K to replace, keep the old one for spare parts. could have been much worse. Sorry that happened to you.
Elevator fluttering like a leaf 😅
All good comments here. My two cents is either an elevator servo failure or elevator flutter due to over speed, dunno.....
Er ist der Meister
Ouch that was painful.. Elevator let go.
It feels like an issue with the elevator servos
Look at the guy picking up the plane by the elevator. It appears he notices something wrong with the elevator. I'm going with 1. linkage failure or not being properly installed or 2. servo failure. Pilot was sketchy from the very start with a brand new plane. I am thinking he did not inspect everything before the flight seeing that he had to stop and fix something on the side. From his takeoffs to the way he was flying... I don't think this was a "radio failure."
Radio failure or rx power issue. The engine dipped twice and then the elevator pointed the thing into the ground.
That looks like a “ I screwed up” moment. I know because I’ve done them.
Maybe dude is a TailHeavy Productions fan. Someone tell him Zack doesn't actually want him to, "Bounce one on" for him. 👍
yeah the elevator looked like it was stuck
Yup, flew it right into the ground!!
0:55 and 1:38 PLEASE do no step in behind the spinning prop like that to make adjustments. That is a ride on the medflight helicopter just waiting to happen.
2:30 the way you are crabbing all over left and right on that approach looks like you are WAY over your head skill level flying this plane. If it was a stiff gusty crosswind I could see it but the trees are barely moving.
5:16 the crash - 2 strong possibilities. #1 something physically broke loose in the elevator (maybe a link came off the servo) causing that flutter like oscillation or #2 if you are using a gyro the gain is too high and you developed a high speed oscillation.
You need to look into your setup and probably get some help and instruction from guys who are experienced with this size of model.
Hello, good morning, dear friends! I notice that in the last seconds of the impact you can hear the acceleration and deceleration of the engine as well as the erratic movement of the rudder and elevator. I am very sorry about the accident. Greetings and good luck. Luke
What was the cause? Sad to see.
Normally I say ' that will fir into a paper bag' ....not this time.
maybe a shopping trolley !!!!!
5:18 it's just like when the dogs go through the trash. omg i can't stop laughing
It's not funny someone's hard work all smashed up you don't seem like a nice person
Elevators dont flutter that slowly.
I noticed the flaps were down the entire flight. I get a new plane takes some getting used to but it seems like the pilot was inexperienced.
was that not a loss of signal because that's normally what happens because flying down wind really doesn't do anything fluttering's caused by a couple of things like servo, or the elevator not being attached right or flying to fast when the elevator was not attached properly if Iam wrong please tell me but that's what I have experienced while fly model planes
good thing he didnt nosedive on the concrete
