Thanks! Yeah, it doesn't really suck more than this. Had to pick it up with a leaf rake (pieces were so small). Complete loss. Bummer but it's part of the hobby.
In my experience with General aviation and RC, High wing tends to pitch up while Low wing tends to pitch down with flap activation. It takes a healthy dose of trim to relieve the control pressure. This has been my experience flying almost the entire lineup of singles from Piper and Cessna as well as a few Mooney's and Beechcraft.
I own a number of low wing r/c planes. One pitches up with flaps, one pitches down and one does not change trim one bit. It seems to depend on whether the flap is simple, split, slotted or Fowler and whether the t/e is straight or swept (forward or aft).
I can relate, I lost a Bryon's Originals Kfir to elevon flutter on the first flight; called them and they said, "oh, you must have gotten an early kit without the counterweight update". A couple hundred hours of work, down the drain and nothing to fly at their event, so I cancelled my trip too.
RCflyyer1, No, never really determined what caused the flutter. The elevator was pulled out from the horizontal stab but we're not sure if the flutter caused that or if it was the cause of the flutter. Sucks but part of the hobby. Gotta move on! :-)
It was both, one works on another, gap makes flutter, flutter increases the gap , it flutters more violently the gap says HA ha you die. Ailerons, elevator and rudder although I've had flaps cause flutter failure too. Everything I build has tight gaps or sealed gaps.
Aarrgghhh!! I cannot imagine how that felt after all those hours of work. Weirdly, it died in a like manner of the real ones that experienced compressibility in a dive and could not pull out.
When I was younger, 35yrs ago I had a quickie 500 with the wing foam core cut for 1/2 thickness and sheet-ed with a webra speed 40 with tuned pipe. I notice that I had a gap in the elevator between it and the stabilizer no slop in the control rod or clevis and thought it would be fine. I could hear it fludder in high speed runs but did not stop flying it. After one such run, the elevator stopped working but the plane wings could roll but that was it. I helplessly watched it flying straight but could not turn it, I picked a spot in the pasture next to ours and killed the engine rolled wings to drop altitude. It looked fine but there was a maintenance road with curb and it skipped into the curb and destroyed all of it, lesson learned.
That was a beautiful aircraft, lots of work. As a full scale pilot who also flies RC, the only time at which you need full power is during take-off. I doubt that the control surfaces were balanced (elevator, rudders, ailerons); flutter usually only occurs at higher (very high speeds), the IMMEDIATE resolution is to reduce airspeed, which MAY allow you to regain control. I know that the crash hurt, and wish you better "luck" in the future. BTW RC flight is much more difficult.
I had flutter in a model once, thread on a pushrod wore off under vibration and the clevis went loose on the rod. Then the aileron started fluttering very fast then the whole wing panel made like a hummingbird. I throttled right back, just a good, lucky instinct I guess. That stopped or mostly stopped the flutter and was able to land it. That was an RCM Trainer 60, that wing is a durable design, I'd added shear webs which the design didn't have so maybe they helped. That's about the only time I know of a model getting bad flutter right through a wing panel and coming home in one piece. I since switched to heavy nylon clevises so it can't happen again. I saw it happen twice more, both times the model tore itself to pieces in a couple of seconds before the pilot fully realised what happened. Once was elevator and the tailplane fell apart then the model was uncontrollable, the other time was aileron like mine and the wing panel disintegrated. You don't want flutter.
The elevator flutter was never completely overcome.According to the test pilots ,even the balance "torpedoes" top and bottom did nothing but endanger pilots bailing out.
+carmium Yes, the elevator fluttered and then I had no elevator control. The elevator came unhinged from the horizontal stab. I did pull the throttles back when it started its dive.
That really sucks. My grandfather did some of the M.E. designs at lockheed for the P-38. He died at 98 a few years ago. We need to dig him up and have a word with him about this!! :-( lol
Elevator buffetting was caused by inboard turning props. When the props were changed to outboard turning that problem was fixed. The balance wights where added to try and help with the problems cause by compressibility at close to Mach 1. This could happen at speeds as low as 425 IAS. That problem wasn't dealt with the insulation of dive brakes on late J and L models. The sad part is they had made kits for every P38 flying that didn't all ready have them. They were loaded on to a C57 and sent to the U.K. only to have the C57 shot down by a RAF Spitfire off the coast.
No. I have read a lot about this and I know RC. On the full size planes, compressibility was the problem. Dive flaps is what fixed it, to extent it could be fixed. From the first-model YP-38 on, the props always turned outboard. I repeat, from YP-38 onward, including every model designed and built thereafter - D, E, F, G, J, L - the props continued to turn outboard. I have no idea where you are getting your information. Do tell. The "prototype" P-38, the XP-38 did have inwardly-rotating engines (before it crashed). However, all subsequent P-38's (including the first batch of YP-38's) had outwardly rotating propellers; Warren M. Bodie, in his book The Lockheed P-38 Lightning: The Definitive Story Of Lockheed's P-38 Fighter, states that, "Engine rotation was changed so that the propellers rotated outboard (at the top), thereby eliminating or at least reducing the downwash onto the wing centersection/fuselage juncture. There was, by then, no doubt that the disturbed airflow, trapped between the two booms, was having an adverse effect on the horizontal stabilizer. No problem was encountered in reversing propeller rotation direction; they merely had to interchange the left and right engines." The kits you refer to getting shot down en route were dive brake kits. And (when they worked), they did prevent pilots from dying in unrecoverable compressibility dives. However the P-38 was never going to make more sense than a Merlin-powered P-51 as a long-range escort in Europe, and so it was soon relegated to other duties once that airplane became available in numbers. P-38s were more complicated to fly, more expensive to build and maintain, and less reliable (in Europe, especially). In any case, this whole presumption is hopelessly wrong. This MODEL P-38 could not have died from compressibility or elevator flutter due to aerodynamic issues at a high Mach number. To suggest that is ignorant of physics. This plane was flying at low altitude (obviously) and low speed (no more than 80-90 mph). It probably died of a poor linkage or electronics - a bad control or servo arm, bad physical or electrical connection, bad or overwhelmed servo or receiver, or some combination. That is the both the simplest and most likely explanation, and by the way, it happens quite often in RC, even with today's better tech. I lost a FW190 to a bad receiver. I almost lost a P-51 to a bad gyro last winter. I've had batteries die unexpectedly. I've had electrical outages. I've had props break off in flight. You name it, fly often enough, it will either happen to you or someone you know. Anyway, sure was heartbreaking to see the crash. Beautiful airplane.
Flutter is a very effective way to re kit a Model. The main reason why I am total OCD about tight slop free surface and I could not give a rat’s hind quarters if it is scale or not!!
Flutter is a sign of a disconnected elevator. I know that feeling. I had a .60 powered sport low wing that gradually went from horizontal to 90 degree vertical with my elevator stick axis feeling like a limp noodle...no connection at all. I saved the tail! :-(
I always figured it's the amount of free play in the control surface or low air pressure at that point that creates the flutter ? but after seeing your hard work trashed it's hard to get motivated back into the long process of construction while that demon lurks ready to leap out and render another airplane scrap bits..but very.Nice 38 anyway..
Absolutely difficult to see these crashes of these thousand dollar aircraft. We didn’t get into the hobby to constantly repair things and rebuild things. I have 400 flights with my $350 Apprentice STS w/ AS3X/SAFE with no crashes over a two year period. Remember, we do this for fun!!!
Also I must add that there may have been too much "slop" within the control system, and the use of lesser power servos (unable to accommodate the forces associated with bigger models, and higher speed) may also be a factor.
@@davidreid8727 Wow you seriously need to do your research, especially before attempting a condescending tone like that and making yourself look like an idiot. They were for what they incorrectly thought was tail flutter. It was discovered almost immediately that they didn't help at all because surprise! The issue wasn't tail flutter. It was kept in the design because it would have cost more to redesign the boom. Jesus, you can even find that in the basic P-38 wikipedia page. Way to instantly show you have no clue what you're talking about.
Yeah, really sucks to feel so helpless! Building a Wingspan Models 1/9th B-17. Will do all I can to prevent flutter!! That couldn't have been good on the Don Smith B-17. Sorry to hear!!
After examining the debris field the RCNTSB should be able to give us the definitive cause of the tragedy rather quickly. After all, it was a small accident.
Thanks Funkhouser! Couldn't rebuild... literally picked it up with a leaf rake. Engines were destroyed with the cylinders bent over and split 90 degrees. The only think salvageable were the landing gear. Still will build another one someday! :-)
Some serious bad luck....I feel for you!!!! If you enjoy the build consider how much you learned from that one and incorporate it into the next!! Good luck!!
wow. just like the full scale, crash from elevator flutter in a dive. it needed some lead ballast on each side of the elevator and not a plastic dummy. or just dont dive aggressively . When your planes get this big it helps to know the flight tendencies of the full scale, as they will start to act like the real thing. An example would be the Bf-109s left wing wanting to stall on take off. Or the P-47s elevator being very sensitive to other wise light compression resulting in lack of elevator authority
One solution to the loss of control in a dive was the switch from inboard turning props to outboard turning. It was found that the inboard turning props would cause tail buffetting a contribute to loss of control of the elevator at high speeds.
Do some research on the plane, please. You will find out the reason they switched the rotation (actually they just swapped the engines) was that pilots got confused when they lost an engine on take-off and the plane would flip inverted under normal engine-out recovery techniques. Maybe the two idiots who replied with bone-numbingly stupid shit will do the same. Fuck, it's amazing how quick the RUclips half-knowing half-wit will get on a video and pontificate with some amazingly stupid shit like they actually know what the fuck they're talking about. As for you, let this be a lesson when you spend 1000 hours building a replica of a 1940s twin-engine prop-fighter, to at least read up on the flight-test procedures and production refinements of the original before you take your own replica out for its first flight.. and maybe google some other attempts ruclips.net/video/bBDLP4onEuY/видео.html
How historically accurate, it couldn’t pull out of a high speed dive. I heard the pilot was on the radio... he was on the canopy, and instrument panel too! 🤣🤣🤣
Really sorry, beautiful plane and a lot of work. They said in the 1940s it was elevator flutter, which balance weights should have fixed. I believe that the air coming over the main wing was too turbulent coming back over the elevator. Some twin boom aircraft have high-mounted elevators for this reason. Good luck on building another one!
No. No on all counts. They originally thought it was tail flutter, but it wasn't. That's why the mass balancers on the tail did absolutely nothing. It was compressibility, which is the center of lift moving farther back than the rear surface of the wing.
Can someone explain to me why some clubs have nice asphalt and still take off/land on the grass? When my field got our asphalt runway we used the hell out of it, so much smoother and nicer
Some feel the grass give more so if a land hard or a prop hits the ground it won't do as much damage. I know many people they'll take off on asphalt, but when they want to land they use grass.
That was a beautiful plane! That is why I stopped flying them,it made me sick when it crashed,all those hours .....smash!!! So I still have a few indoor helicopters and a R.C funny car that goes about 100 mph,but I let my friend fly my only plane,that way I have someone to yell at!
@@israelrivera835 I hate these crashes it makes me ill. My hat off to RC pilots, I flew for 40 years commercially and give me any RC plane and I guarantee it would be a smoking hole in a corn field in double quick time. Beautiful plane
Lucky that all the pieces are still in tact, so a little glue, spit and elbow grease, and it's good as new. Next time i would built a model and do alot of flight test, and when al the bugs are gone and the plane is still in tact, then i would start the detailing.
Very sad 😥. All that work. Everyone knows, Anytime you have a crash, no matter how much or little time you have invested in your aircraft, it's a sickly feeling.
I gave the video a dislike only because I felt the pain that the builder went through. The video was Excellent, so I guess you could say I liked the video. I just hated to see such a Beautiful aircraft crash. I'm sorry for the loss of your airplane. The up side to this is that you can always build another one.
recently had this happen on a less expensive plane. It was an escapade 40. Elevator fluttered than cracked. Do you have any idea to have what caused the flutter?
I would presume the servo was faulty or not strong enough to handle the task it was given. Bad electrical connection would be next guess. I have a P-38 (RC) and refuse to believe elevator flutter happens at such comparatively low speeds. I have certainly never had any trouble with it, and I don't know any one else (with a P-38) who has. Seems really implausible given low speeds involved, etc.
I think I'd toss my cookies if I watched all that work evaporate in a minute and a half of flight. Does the thought of stamp collecting ever go through your head when you take one on the chin like that? Oi!
djstar39 Trust me I think I have more experience at crashing & rebuilding planes then most people. When I was just learning to fly 30 years ago there wasn't many experienced pilots around where I lived so I was totally on my own, I must have completely destroyed at least 5 Tower Hobbies/Great Planes .40 size "trainers" & rebuilt another 6😂😂😁😁. But I finally got it and have been hooked/addicted ever since. I also realize if you're not prepared to face the inevitable that at any time every plane, helicopter, & drone can and will crash, then this isn't the hobby for you. Crashing a plane like a Ziroli is a little more painful then your run of the mill ARF, not only for the $$$$ signs it the time and effort that goes into that kind of build.
As Worf might say- "It died well"
Thanks! Yeah, it doesn't really suck more than this. Had to pick it up with a leaf rake (pieces were so small). Complete loss. Bummer but it's part of the hobby.
I got a _bad_ feeling when I heard the discussion about control surfaces at 0:57
I thought to myself _"Nothing good can come of this."_
In my experience with General aviation and RC, High wing tends to pitch up while Low wing tends to pitch down with flap activation. It takes a healthy dose of trim to relieve the control pressure. This has been my experience flying almost the entire lineup of singles from Piper and Cessna as well as a few Mooney's and Beechcraft.

heavy model, big engines, flying at full power, max speed.
ANy slight mistake in linkages or hinges will do that.
most of them seem to wipe out.
minus the ball of flames it was a very convincing crash impact for a model.
Hahaha what? I'd love to see all these impacts you remember where the entirety of the airframe of a real plane is demolished.

So many questions, please report!
The squirrel suffered head damage but turned his wings into the CO and wants to be posted to S-4
@@thomasmcewen5493 That crash was really Catastrophic!😬 Can't tell it was a beautiful plane once, my condolences to the owners!🙁
@@israelrivera835 I hate these crashes it makes me ill. My hat off to RC pilots, I flew for 40 years commercially and give me any RC plane and I guarantee it would be a smoking hole in a corn field in double quick time. Beautiful plane
Thanks Ken! It does suck! Part of the hobby though...
Wow, great job with the zoom lens....
Lucky that all the pieces are still in tact, so a little glue, spit and elbow grease, and it's good as new.
Next time i would built a model and do alot of flight test, and when al the bugs are gone and the plane
is still in tact, then i would start the detailing.
...no shit. I guarantee that's exactly what he did. Are you completely unaware of mechanical failure?
First flight is always a shake down flight...never fly twice until you tear it down and check OUT EVERYTHING!!!!!
Really a big bummer. Such a beautiful plane. Sorry to see that happen and a huge disappointment.
Very sad 😥. All that work. Everyone knows, Anytime you have a crash, no matter how much or little time you have invested in your aircraft, it's a sickly feeling.
If this was a ARF, Guy's would be screeming bloody murder...
And how it was the ARF company's fualt for the flutter...
Bogus! Heinous! Most non-triumphant!
"Ah crap." Sums it up. His wallet just started to cry.
I gave the video a dislike only because I felt the pain that the builder went through. The video was Excellent, so I guess you could say I liked the video. I just hated to see such a Beautiful aircraft crash. I'm sorry for the loss of your airplane. The up side to this is that you can always build another one.
Or a complete idiot, I meant to say.
Oh man, what a good looking and great sounding model. Good you have it on video. Safety first. Kill the dead engines. Flew nice for a bit.
Ouch!. Thats gotta hurt!.
I did not see a parachute. How did the pilot fare? Hope he survived.
Sorry for your loss,,,
You turned it back into a kit.bummer.
The worst accident ever is the camera use! Why so wobbly and out of focus?
a failure and crash can be a quikling of 25 cent
sorry for your loss! I like how at the end the guy says "kill the engines" i think they are killed mate
Thanks! Yep, killed is right. We found the engines about 280 feet away in the beans with the cylinders bent in half.
What a bloody shame. Sorry that happened.
Sucks. Was a gorgeous airplane.
Man it really turned into confetti
I’ve been a NTSB investigator for at least 20 maybe 25 sec and I can tell you the cause of this crash was the the aircraft was flying to low.
Does anyone make kits of carbon fiber materials?
Another 'unplanned obsolesence' flight...
Why did I get up this morning moment.
recently had this happen on a less expensive plane. It was an escapade 40. Elevator fluttered than cracked. Do you have any idea to have what caused the flutter?
I would presume the servo was faulty or not strong enough to handle the task it was given. Bad electrical connection would be next guess. I have a P-38 (RC) and refuse to believe elevator flutter happens at such comparatively low speeds. I have certainly never had any trouble with it, and I don't know any one else (with a P-38) who has. Seems really implausible given low speeds involved, etc.
And that’s the end of playtime boys, time to go home for dinner
Heartbreaking
OOHHH MAN........That is just so hard to watch!
That's got to suck big time.
BTW how much of a sucking was tgat??
Que macana cuál fue el problema 😢
Wow ure vid is got to be the clearest ever is it ure camera or the way u uploaded.?
Probably the camera... it's a Sony HD camera. Thanks!!
It’s better to give a call to Kelly Johnson to understand what went wrong.
Or Burt Rutan.
Skip to 1:50 for the fun part.
BEAUTIFUL CRASH! Loved it!
I think I'd toss my cookies if I watched all that work evaporate in a minute and a half of flight. Does the thought of stamp collecting ever go through your head when you take one on the chin like that? Oi!
Take that Mother Earth!!! Seriously that’s a bummer 😞
It was so terrible, I had to watch it five times.
There should be a r.c. rescue company standing by with r.c. ambulances and fire trucks...
LOL!! That was funny! Do it again! do it again!!!
heart breaking awful
Man that's hard to watch!
Dick Dastardly, yeah it was tough. Part of the hobby though. Building another one. At the fiberglass stage.
djstar39 Trust me I think I have more experience at crashing & rebuilding planes then most people. When I was just learning to fly 30 years ago there wasn't many experienced pilots around where I lived so I was totally on my own, I must have completely destroyed at least 5 Tower Hobbies/Great Planes .40 size "trainers" & rebuilt another 6😂😂😁😁. But I finally got it and have been hooked/addicted ever since. I also realize if you're not prepared to face the inevitable that at any time every plane, helicopter, & drone can and will crash, then this isn't the hobby for you. Crashing a plane like a Ziroli is a little more painful then your run of the mill ARF, not only for the $$$$ signs it the time and effort that goes into that kind of build.
Build me one too now when youre at it. ;o)
That's a shame, been there done that.
"Oh crap" indeed!
It's my experience that all airplanes are doomed to crash
All RC airplanes have an expiration date stamped on them. I just don't ever seem to be able to find the stamp before the time runs out!
@@JustFlyIt09 I've crashed everything I've ever had, usually foamies
