At first I thought down elevator instead of up caused the crash but indeed you can hear the flutter just before it dives into the ground... Sad and sorry for your loss it was a beautiful plane.
It is from the control surfaces not being strong enough to overcome the air speed, weak linkage, servos, or even the surface itself can cause it and when it happens you must slow down to stop it. Flutter can tear your plane apart in the air without hitting the ground. Being up high would help if indeed you slowed down fast enough. Flutter is usually very violent and rips things apart.
Amazing! This is exactly the situation, I experienced on my 3.5 Meter ASW 24, while doing a dive! My buddy shouted "watch out, she's lowering her "ears" (=wings / wing tips, which means "undercut"), and I either noticed that she did not react in any way on pulling the elevator! My buddy shouted "Spoilers! Spoilers!" so I did, and that obviously rescued my ASW24, as she regained to react on elevators! but that has been in a much greater height than yours! So you definetly had no chance to react! Sorry for your loss!
I would say that this is not an “over speed” but a poorly rigged elevator and/or linkage system. A composite Ventus is plenty capable of high speed passes. I’m sorry for your loss and hopefully you can build another! Beautiful glider
Let me ask you a question? So you fly Model Airplanes the size of the ventus schown? Because its really easy to say it was Pilot error But if you would actually know what Your Talking about you would know that if a Big Model plane is Comming straight towards you can‘t actually guess the Speed… also you Where Not present so you don‘t Even know all the Details its just dump and disrespectful towards the Pilot
@argduck yes I do fly models that size. A 6m Discus 2c and a 6m Ash 26 amoung others. I'm a retired fullsize gliding instructor and life time aviator. NO disrespect intended but I might have the experience to make the comment.
That speed with a Ventus should not have been a problem. Not sure what kit it was but maybe not a good one. What can happen is poorly built wings will at high speed twist into a negative position and dive in.
The horizontal stabilizer command failed, which is why this dive down in the last meters occurred. I don't believe it was caused by a movement of your hand. I think there is some design flaw. It is quite possible that at this speed the steering machine did not have enough power to push the horizontal stabilizer up. At a height of about 5 meters, a clearly perceptible flutter was heard and then the glider plunged down. The whirring sound the last meters before impact was a flutter. Be healthy! One learns every day while one lives!
@@theresnobodyhere5778 servo is strong enought, its Futaba BLS-451... very precise servo... Whole horizontal tail got flater :/ When you loose horizontal tail on any airplane/glider, nose goes down...
@@flying.fox987 Really tragic, but usually it is only the control surfaces that flutter, finding or guessing the cause is very hard sometimes. generally due to as you said overspeed, but what failed first is always the question or was there something other than the speed that initiated the flutter. weak tail boom, servo at its limit when you pulled up elevator, who knows. I did not hear the flutter on the video before you started to pull up, but I was not there and the music was a little loud. I experienced flutter on an ASW27 5 meter but luckily landed with one aileron ( I had altitude to recover), another time with a 5.8 meter Bruckman Swift 42% I exceeded the VNE in a vertical maneuver, what actually failed first is unknown, but an aileron fluttered and transferred the harmonics to all the ailerons , I was able to pull out, and landed the plane thankfully with rudder and elevator alone. The wing was full carbon layup, so it was rigid enough, servos were JR 8411 with over 200 in/oz of torque. The forces are amazing in these circumstances. The sound is one you never forget.
@@flying.fox987 could it be the problem with linkage? I’ve seen recently that in DS (Dynamic Soaring) one of the steps they made to go even faster was to have servo horns PARALLEL to the pushrods to make it more rigid.
Video ist alt.............; hab's erst vor kurzem entdeckt....... // kleine Frage: was macht Dich so sicher, dass der Rumpfhinterteil sich zuerst "verabschiedet" hatte ? / via slowmo im Video sieht man das nicht + Absturzbilder zeugen auch nicht unbedingt davon.... // wie sieht es betr. der Vne-Frage aus ?
So you basically lost elevator control? The elevator servo was mounted in the cockpit area and running a cable pushrod up the vertical stab to the elevator? The elevator servo should have been mounted in the vertical stab with a direct, solid pushrod to the elevator. Just my opinion. Sorry for your loss.
At first I thought down elevator instead of up caused the crash but indeed you can hear the flutter just before it dives into the ground... Sad and sorry for your loss it was a beautiful plane.
Wie kommt flattern zustande? Sollte es in größerer Höhe passieren, kann das Modell überleben?

Sorry for your glider and the background music of the video.
That was outstanding sir.
I know 🤷♂️
Why not edit the video and add the 5-10 sec of crash with actual live sound without music ???
Wow you can actually hear the flutter just before impact. Sorry for your loss.
Only just, under that crap music!
Unverantwortlich wie dieser Pilot überhaupt sein Modell bewegt....man fliegt niemals so nahe an menschen vorbei
Sorry for your loss.
Thanks.
Ohh Boze!!! sorry for the crash !!
Uh ah oh. Šteta Fox...divna fučkalica. Ništa, hotliner znači :)
Pilot error. That pilot has learnt that every glider has a VNE. The bank and dive before the finals would have done the damage.

ooouch.....hate to watch that. But I have seen that same incident many times!.
Good looking bird. It is a tough loss for sure.
Every plane has a VNE. You just found it on this one.
VNE = Very nasty experience............as well as Never exceed speed!

Was there some flutter noise?
Yes, it was the reason for crash 🤷🏼♂️😒
That's a sad loss.
ooh, expensive, happened on April the first as well..
Yes, expencive...
Actualy day before April first...
Des woars Franzl.😮😢
😲 ooooooo nooooo
Who manufactured this plane?
Topmodel
gutting!
What servo you had on the tail?
Futaba BLS-451
Add identifies as a P38
da brach was ..die Belastung wurde zu groß
Uh, šteta!
Je, nažalost...
Sorry, bro.
😢
Pilot’s error
Than watch it again, with sound....
it looked like it was coming out of the curve perfect then you pushed stick forwards nose dived it 😭😭🤔🤔😞
I started slowly pulling up, but then horizontal tail got flater/torsion (the sound you can hear 1-2 seconds before it hits the ground) :(
@@flying.fox987 ahh yehh, do you think stronger servos would ve help beat the force maybe not would just bend push rod

Ooooooooooh fuuuuuuck
Cosa era successo
Flutter on the elevator....

@@joebushor6857 servo was in vertical stab...
I dont think the problem was on servo or push rod, but the elevator. It is fully delaminated after...
…crashed because of overspeeding…is indicated when aeroplane is piloted into the ground with as high speed as physical possible…
