Pilot obviously did numerous things wrong.
Trying to fly too early, too steep a climb for the speed, inexperience shines through here.
Great camera work!
So great, I blocked this channel.
1. Pre-rotate to recommended RRPM.
2. Accelerate until nose lifts
3. Push nose down until wheel is slightly of the ground
4. After lifting of the ground fly straight until recommended climb speed is reached
DO NOT PULL UP TO EARLY!
Nice camera work !!
"I told you to put that thing back in the hangar!" "OK".
Ive been at study on thus procedure by no experience, once the nose rises you hold wing a little forward?
Yes, you move the stick forward, when the front wheel leaves the ground and keep it off the ground, ideally not hitting the tail on the ground. If you just keep it in the balance, while accelerating, the gyroplane will just softly lift off.
@@gyrocopterkai or the blade hittin the ground behind you.
Person doing the videoing...find another career or even hobby.
I thought he very well captured the color and character of the grass :)
There were 2 more gyroplane accidents on 2-Sep. One instructor with his pupil crashed them on the same day. I do not know, however, if any of these two were involved in this accident
if the guy in the arrowcopter had had a tail wheel limiting the gyroplane nose up pitch to 9°, the gyroplane could not have taken off and he would have aborted the take off.
in the absence of such a tail wheel the gyro has taken off but the angle of attack rotor was so big that the gyro immediately passed behind the power curve and crashed ...
Drop keels are ok for experienced pilots.
this is just my opinion of course I am not a fill of science, this is just what I noticed over my own experience.
wo hatte der Pilot seine ausbildung gemacht ? Spielekonsole????
Appears to be an airplane takeoff. Clearly, the pilot had not been properly trained.
you are right most people able to pay for such a gyroplane come from fixed wing aviation, most of the time those people are 60 years old and their instructor provides then a quick dual training in order to sell the gyro .
the point is that a gyro is not a FW aircraft you are right ..
a short dual training is not enough .this king of gyroplane are designed so that the front wheel can raise very high and place the gyroplane rotor at a high angle of attack .. an once at this angle of attack the gyroplane will leave the ground ... the trouble is that the rotor drag is so huge that the gyroplane will get behind the power curve and touch down again
if this bad pilot had spend more time on dual training learning to push the stick, when the front wheel begin the get lighter (and not when it raises), the gyro would have taken off 3 wheels with a mild angle of attack, he would have accelerated on ground effect and started his initial ascent.
but even if he had been properly trained, it doesn not mean that he would had succeded in all of his take offs
the solution that we home builders are using is to use a tail wheel that prevents the gyro to lift it's nose more then 10° on the ground at least until we get use to our gyroplane that by defition no on will teach to fly ..
with such a tail wheel when the pilot will botch his take off pushing the stick after the front wheel lifts the tail wheel will prevent the gyro to take off .. the pilot will hear a vivration and then pull back the throttle and abort..
generally speaking people who have built monoseaters for decades taking off without pre-rotators know what is called rotor management
they were pre-rotating manually at 40 rpm and then taxi with a mild rotor angle (and certainly not stick full back with their rotor at high angle of attack), applying a small amount of throttle.
they did not have anly rotor tachometer at all, once thier rotor would bluring , it would show them that the rotor was sminning above 100 rpm, they would increase a little bit the rotor angle an apply more power .. and magically the gyroplane would become airborn the 3 wheels at the same time, and they would not even have to push the stick to accelerate on the ground effect.
trouble is that when "modern" tandems arrivec and when dual training arrived , a new technique was invented to permit stupis pilots to take off ..
they are pre-rotating fully at 240 rpm, stick fully back and then apply throttle until the front wheen comes off ... and one time out of 3 the gyro finds itself with a too big angle, fortunately , most of the time they correct things pushing the stick ahead to get out of trouble ..
but not all the time... and with drop keels gyro, things are even worst ...
money can't make a gyroplane pilot ... money can't teach pilots the good reflexes ...
the solution to teach them all of this is to make the trainees pre-rotate to 80/100 rpm not more and learn to accelerate the rotor without flapping it ... this is something some instructors do .. but they don't have the time to do this ... most of them don't even how to do this ..
the guy was properly trained, he properly pre-rotated hus rotor, then fully banked his rotor backward, applied reasonnable power but he did not anticipate the moment the front wheel would lift and failed to push the stick early enough to prevent the gyro rotor to get a dramatic angle of attack lifting the gyro and getting the gyro behind the power curve.
if this pilot had been in a magni (for example), the tail wheel would have touched the ground limiting the rotor angle of attack making it impossible to the gyro to take off.
the pilot would have been forced to push the stick or to abort landing.
a magni (or any other gyro with a low tail wheel) are forgiving and teach the pilot to properly anticipate the front wheel lift.
gyros with a drop keel are not forgiving ... and only one fault can destroy an expensive gyroplane ..
Neither was the camera man
@@edhastie6074 hello , I did not get you , neither who ?
@jean michel Urbani I heard 2 of the same aircraft at the same airport crashed the same day. Is this true?
Not sure who was worse, the pilot or the camera operator.
If you use any equipment wrong it can hurt...
What can anyone say about this... Clearly rotor not up to speed when pilot pulls on the stick. Behind the curve, the gyro sinks, hits the ground, though the pilot tries to correct, is too late, and runs into a hangar. These type of accidents are all over youtube, and makes one wonder what kind of training these people are getting.
If the rotors were not up to speed it wouldnt have left the ground.
This was over rotation, unawareness of said over rotation until too late and sinking because all the lidt was pointing against the direction of travel.
@@cameronlapworth2284 What is overrotation? Could this be caused by being heavier than usual?
@@KilledMind1985 not balancing on the mains so you get off flat. So he ended up nose high behind the power curve. The body is rotated at too high an angle.
The fundermental problem is no one teaches people to wind up rotors properly anymore. Instead of a progressive gentle and gradual build up they spin up to 220 full power so they can try to avoid blade flap. Proper wind up technique has a slower inital speed and only applies full power when the rotor can handle it. This actually uses less airstrip and is easier to manage.
Why cant they design a gyrocopter to spool up the rotor at full RPM and perhaps not half to pull the cyclic full aft during take off? or At least keep the pre rotator running till so the pilot could keep the rotor disk level till proper speed is achieved ? thanks
it is not difficult to do it correctly. A little bit of training and you never make those mistakes. Yes, automating everything would possibly prevent accidents like this, but landing is much harder than taking off, so what else should we automate before it becomes a drone.
@@gyrocopterkai lol No sir I would not want to Automate it, just wondering if the pilot could run the prerotator to 300 or higher Rpm if that would make it easier or safer during take off. I come from Helicopters but gryro copters look interesting!
@@FalconWing1813 some allow to pre-rotate to almost 250, then already the front wheel gets light. In a gyrocopter you want forward speed before you take off. I agree, it is a good idea to keep the pre-rotator engaged while you start your take-off-run, I had a gyro which could do that. But when the front wheel lifts, you want to have forward speed already, otherwise you get into an uncontrollable situation with the torque turning the cabin. Also, with every couple of rpms added, you need a beefier pre-rotator-setup, which adds weight and complexity.
@@gyrocopterkai That makes since!
@@gyrocopterkai But with the prerotator off, there is no torque right?
Os, was there 2 accidents at the same airport on the same day?
Incompetent pilot. Gets you every time.
That looked like a crash right from the end of pre-rotation.
Understand weight to power ratio, pre-rotate to correct RPM, wait to rotate off ground, when lifts nose, level to build up ground effect energy to increase ground speed, increase power to safely lift. No sudden stick movements to create steep turns until a safe altitude is achieved. (you have a passenger!)
All he had to do is point that phone to the aircraft! Most likely friend of the pilot 🛩
Nice parking! 👍😁
Kdyz si to plete s klasickym letadlem s pevnmi nosnymi plochami no tak si to zapamatuje pro priste
Bein too anxious. If im not mistaken , unlike a plane this type is what you hold back down till flying speed and clearance to climb out
Yes, see my answer above. First hold stick all the way back, while pushing the throttle forward, until the front wheel lifts, then keep it off the ground without letting the tail drop to the ground (some have tail-wheels) and then it will just lift off.
Brilliant camera work.
The cameraman had one job to do. Keep the camera on the subject.😂
The camera man was not a professional but probably a friend or relative of one of the people in the accident. Duh
They might not stall, but they do sink.
How many accidents before this is stopped?
Until what is stopped? Flying? Bad piloting?
Ur comment is poorly worded and lacks knowledge
If instructors let people like him fly, something is really wrong. And two or may be three accidents on a same day on a small field? WTF?
What? Are you serious? You want to make everything human proof? A utopia of no risk and totally fool proof? That thought process is the most dangerous and deadly entity I have yet to encounter. Well you do have a mechanism to do this and it has signs of working. Make everything so expensive no one can do anything but thumb their smartphone and dream of what could be or did exist at one time. Now go sit one your couch and wait to die.
Now that's a question which screams utter ignorance of just about every aspect of this accident (note use of the word 'accident').
You obviously know nothing about the engineering, reliability, standards or aerodynamics of gyrocopters.
You have an equally abundent knowledge of pilot training, psychology, airmanship, flight conditions or any understandable explanation for why this happened.
Crash and accident analysis would not be a career for you.
two problems: pilot error causes loss of bucks.........; uncapable cam man causes pissed of viewers...............
L'autogyre n'est pas donné à tout le monde 🫣
Clearly it was not ready to fly.
YOU saw it here folks!...not
Did anyone know Pilot or owner for airplane pls DM me
Looks like a partial loss of power
no, actually trying to lift off too early, before the rotor had sufficient RPMs.
I bet you can't land in the hangar! Hold my beer.
Оператору больше не наливать!
These are death traps
No, they are not. You just have to not be an idiot, then they are the safest aircraft to fly. No stall, no spin, very slow landing speed.
Didn't stand a farts chance in the wind...
dual training must not be performed on a gyroplane with a drop keel.. a well designed gyro has a taill wheel placed so that when the bad pilots don't push the stick immediately after the front wheel lifts , the gyro can't up nose at more then 10°.. and at 10° the gyro can't take off .. the taill wheel will only make a groove in the grass and the pilot will pull back throttle and abort take off .. with a drop keel the gyro jumps and immediately gets behind the power curve ... what is incredible is that the isntructor did not immediately pull bache the throttle ... if he was consious of course ...
I don't think that matters, you can still do the wrong thing after the nose has taken off.
I see what you mean. I believe the Magnis are built that way, that you can keep pulling back the stick and just take off, because of the lower tail-wheel. However, at some stage, you need to stop pulling back after take-off otherwise the same will happen, as we see here, but later and possibly with greater damage. I also agree, good training is required and the flight instructor should be awake and react.
@@gyrocopterkai hello .. with a low tail wheel if you fail pushing the stick immediately after the front wheel begin to lift, the tail wheel will touche the ground and prevent the gyro rotor to have a sufficient angle of attack to lift the gyro .. so the gyro won't take off .. you won't crash ...
what I am saying is not theoretical, this something I have experienced myself when I tested my mono seater
when I would fail to push the stick immediately after the gyro would not take off at all because I only have a 9° nose up pitch angle.
please try this on a Magni ..
it does not mean that a drop keel is not a good thing , it is a bad thing for young pilots ..
Doesn't matter if it's a drop keel it was poor technique plain and simple. Pilot didn't accelerate to the proper airspeed before pulling up.
@@ictpilot ok show us a video of you taking off accelerating before pulling the stick .... hahah excellent ... call the firemen , and book a hospital room or a coffin ....
And the photography award goes to………………………🤦🏾♂️
Out of Basic！
JUNK ?
Pilot fault!
All these tubs have the same issues - These 'pilots' try and fly them like fixed wing aircraft
Круто задрал-видимо ошибка в пилотировании.
What a dope 😮
Wie sie sehen, sehen sie garnichts
Kamikaze machines !!! 🚀
The machine is alright but the pilots went Kamikaze
😂😂😂😂😂😂😅😅😅😅😅
🤣🤣🤣🤣🤣🤣🤣🤣🤣
Gasoline motors attract narcissist who know absolutely nothing about flying aircraft they think they can just use a lot of power and just fly and impress every 1At a tracks narcissist and reprobates gasoline motors instant success of attraction
I bet the Europa owner wasn’t too chuffed either.🫣
