Dude the pilot is skilled, at that speed there's no place for mistakes. Respect ✊
Skiedit3:
Skilled pilot?
Not only him, I include designer and constructor of the rocke... sorry, the plane!
Regards!
That is just what I was thinking crazy kool 😊😊😊
i wonder if there is some kind of aerodynamics control system between the pilot and flaps
@@falpikikos What do you mean exactly? If you're talking about flap control. Yes, it's all possible to program this in the transmitter. There's a lot of available buttons/switches that can be used ;)
Right samething I was thinking can barely fly my drone without crashing let alone this.
Whoever recorded this has insane skill to film a plane that small going that fast that well.
Shades Loas probably filmed them self’s wanking a lot
Not to mention the person who controls it
Mostly the person controlling it.
That’s because it’s not going 500
unless it's internally mounted (maybe fuselage could accomodate one small gopro cube) but it would have to point towards ground or into some angle...
The steady hand of the pilot is probably even more amazing than that screaming beast in the sky.
And the cameraman is extremely good too. Thanks for the wonderful experience!
I know right... no one's mentioning the cameraman skills...

Steven Arnold I thought the Egyptian’s invented beer? Oh! You meant “REALLY GOOD” beer.
@Steven Arnold I'm originally from Ulm Germany (Schwabenland). =)
@Dupa Essex 🤦♂️🤦♂️🙄
The sound at 1:40 is probably the coolest sound I've ever heard. It's something out of this world.
so cooooollll
Alien plane???
Stuka siren
@@francois1048 i thought that too
Completely agree!!! Can’t understand why anyone wouldn’t luv that sound.
That dopler effect is such sweet music. 😁
Thinking just that
Like a formula 1
For such a fast plane it actually flies quite gracefully at low speeds. Nice flying and camera skills.
That's the coolest thing about hotliners.
One of the best sounding electric planes I’ve ever heard.
Nah dude, thats waaaaay better ua-cam.com/video/1Bv3WlcLJq8/v-deo.html
@@lars9966 those are not electric
@@_Stupid_Idiot and?
@@lars9966 read the original comment dipshit.
Sounds like a Formula 1 car
Not anymore lol
Actually it sounds more Formula 1 than Formula 1.
@@mitch832 right? Lol
Sounds like a Stuka in a dive bomb strafe.
Absolutely! F1
Man that sound tho 😃 👍🏽
Besser und vor allem schneller als jeder Ferrari!
Sounds like a v12 f1 😂😂😂😂😂😂
F1 has a v6 turbo
Buggati had w6 so technically that’s v12 for buggati
@@romainolaya1295 F1 has v6 turbo today, but not back in the days! they had v12 went for v10 then v8, and now v6 TT. all that because of fuel efficiency, look it up different f1 sounds. the v12 sounds just like when the rc plane passes you
Albeit a slightly higher pitch but yeah it does.
1:39
Add FPV to it and you will learn what latency means.
I wonder if fpv would even work at such speeds because of the Doppler effect...
@@linuspauly2380 I don't understand how Doppler effect should exactly influence FPV?
@@jendabekCZ rf waves are traveling at light speed there's no latency except in the circuits
SauerlandFpV not in air
@@sauerlandfpv5425 I guess he means the lag of the cam itself not the vtx.
It says in the description that it’s a 12 inch by 25 prop. This means for every rotation or 360* it moves the plane 25 inches forward. For it to go 308 mph, it would need to spin 780,600 times in an hour to get it this far in that time, or 13,000 times a minute, or 216 times a second.
The distance the tip of the prop needs to travel for a whole revolution is 47 inches (15*3.14). 47 inches * 216 is 10,152 inches per second, or 257 meters per second.
This figure is based off of a 100% propellor efficiency. As the speed of a prop increase and the plane moves faster the efficiency rises gradually then drops dramatically. Also propellers slip, and air is compressible, so energy is wasted. This means that for the plane to hit 308 mph, using a propellor, which typically sit at just above 55-60%.
60% of 247 is 154. Using this we can work out that the tip of the prop is moving at 411mp/s. This means it is breaking the sound barrier.
This figure however is going to be inaccurate due to pitch and prevailing conditions.
Still though... Interesting
Ryan M. Unfortunately your calculation is too simplistic. You're not taking into account propeller slip. For normal aircraft you can use around 85% efficiency however in this ultra-high-speed application it could be much less.
Therefore that should be enough to push the prop into a supersonic zone.
otm646 I know, but I was just doing this early morning and tired. let me edit this. I know the calculations and I’ll do them now
And you have not taken in consideration of the wind speed, wind direction, the weather, heat, vapour..
Try again when u have the correct measurement..
Jason Hong this is a estimate, using pre established, perfect conditions.
There isn’t enough info to do it actually.
If you want to criticise, then why don’t you do it precisely, and then I’ll judge you, yeah?
Jason Hong what the fuck... why an essay?
Look, the reason I wrote this is because further down someone said they could hear shockwaves from the props. I was interested and so calculated it, and replied, showing my working. Not to show off knowledge or anything, I’m not that kind of guy. PLUS it also had the added benefit of being part of my assignment I got from my aerospace engineering my prof gave me, so I did my homework while satisfying my own interests, and only as an added perk, showing others.
This is not RC, this is a weapon ...
I was just thinking that. Strap a light bomb to that thing and anyone could take down an aircraft. Scary thought.
velveetaslingshot
Even antrax would make it a small citizen controlled missile.
velveetaslingshot sorry but an explosive on this is like putting a rock on a paper airplane
@@rubydog25 Yep. Payloads are out of the question for this thing.
@EF drone is much more easier to weaponize tho
What baffles me must be how they packed such a powerful motor and battery in such thin and small fuselage...
Leonardo Bonanno that’s easy the hard part is finding a servo with enough torque but still small enough to fit in the plane and for it to have enough power to move The control services in 300+ mile an hour winds.
Thats easy finding the $$ for said items is the hard part!
Leonardo Bonanno maxon motor?
Better yet, the design of the wings would suggest at a static rest that it would be torn apart at those speeds... but obviously not. Very cool.
It might be two smaller, but narrower batteries wired to make the required voltage.
THATS SO IMPRESSIVE!!!!
No way that is 308mph! Much closer to 309mph.
Darrell Latham haha good one 👍
To me it looks like 308.673 mph. You can’t see it ?
Darrell Latham Lmao😆
Bollocks. 307 tops. Give or take 1 or 2.
It's actually going 618mph minus 309mph
1:38 that sound is amazing
The pilot is skilled? Let’s talk about the camera man.
IS WONDERFULL
I've seen this clip at least 10 times still can't get enough of it. Such a slick plane, hats off to the pilot! 👍👌
Camera recorded with 1/2 speed ?
+Franc
No, and that's actually slow, this is more like it: ua-cam.com/video/hFPJ6DUAY10/v-deo.html
+Bari
And Iv'e seen this about 10 times: ua-cam.com/video/hFPJ6DUAY10/v-deo.html
and dont forget about the builder! to get such a slick design, needs to be perfectly aerodynamic and pretty strong junctions to withstand the high G forces
Me too!
Wow !
Absolutely amazing..
CRAZY insane fast .
Love it , Love it 💘
Excellent pilot .
Nice flying !!!
Joe .
Best ever RC plane......😍😍😍😍😍😍😍
Wooooow what BEAUTIFUL SCENERY!!! cool plane 😎👍
What a BEAUTIFUL sound! Flying was great too! 😆
Sounds like one of those bombers during WWII.
MyYTChannel giggidy
Stuka
the German Buzz Bomb -- a mini engine / bomb able for flight until fuel ran out then BOOM !!!!
JAFO FUBAR nah, JU-87.
Sven Felsl doesn't need to there's plenty of information available about them.
in the good ole days when my best flying buddy Rut was still arround ( R.I.P. my best friend 😭) we challanged each other to fly the same speed pattern as in this video as fast as we could with a plane called a " poezie" it had a .61 os max , tuned pipe etc. the goal was who had the biggest chahones to fly as low and as fast past the field from as hi as a dive as possible 😁😁🤣 Record was from max allowed altitude ( we where close to eindhoven airport ) with the wheels touching the grass sqeeuking sound and pull up and do it again. One of the best memories of my best passed away friend. Miss you Rut. Will never forget you my friend.
Krank,absolut krank diese Geschwindigkeit und das mit nem Propeller :D und ein hammer sound
That's insane! I would've loved to see the look on the Wright brothers faces if time travel were possible?!
Better still take [them] to a modern airport, show [them an] aircraft carrier, or show them the SR-71.
They would eat their hats😎
Did you mean Santos Dumont, the man who invented the airplane?
Ariel
No. He means the Wright brothers. Eric and Roger, big fans of model planes back in the 70's.
do you expect them to somehow drop their jaws at something they know is possible instead of at the *fucking time machine* itself?
Imagine the gropro footage from that thing
bhaven arora I dont think a Gopro has the frames per second for that thing😎
BALAZSER1 60FPS Is enough
Was just thinking the same thing.
Screw GoPro...how about real-time Wi-Fi? That would be even better because the pilot could do so much more and test distance etc...just like a drone.
Flying with that head set they wear for racing drones that would be the to kool right .
Beautiful, and what a fantastic looking aeroplane..................and the sound, magnificent achievement.
This might be the best thing (living, dead, real, fake, happy or sad) I have ever witnessed on UA-cam. Words escape me.
I bet that's pulling 10g on pull up nice
they actually are more in the order of 50-100g in tight pulls. As you can imagine the radius is much smaller, but the speed is roughly the same as a fighter jet at takeoff speed.
Dave Robertson
There is no need to be condescending, we are all here to enjoy this video and learn something.
@flyingeagle357 At 500km/h you have to turn with a 20m radius to get 100*g. I'd guess this thing can do it.
Ardalan G. He wasn’t taking about grams dummy
@flyingeagle357 a fly could.
Thats crazy! The sound while speeding up is incredible!
I ve subscribed to this craziest flying rc. The pilot superb. omg!!!
Skills of Pilot,
Skills of Airplane Builder,
Skills of Camera coverage,
Skills of plenty others who made this real,
Insane Multiple skills in one video !
Sounds like the prop tips are going supersonic?!
esuohdica oh, for sure.
Definitely
No, not at all, the prop ist just 'stalling', like a wing at a to high angle of attack (search for "stall" if you want to understand it). A Prop acts as a rotating wing. It stalls more at low air speed and high rev's. That makes some serious noise at this power level and it disapperaes at higher air speed. You have to think about it a bit to really understand it, actually not self explaining.
esuohdica Probably.
God damn inch.
I'm blown away at the skills that must be required to fly these things. Like how does he know when to pull up etc so you don't end up nose diving into the ground. The whole thing is amazing.
The pilot has a real pilot license
If you have been flying for years_ decades.. You get the feeling of it.
I'm sure he's had lots of planes in the past. You don't normally build or fly something like this for your first 100 planes lol
@@feralkittiesforyou8914
Yeah, it's the same with people who have never ridden a motorcycle in their lives and they go out and buy a crotch rocket. You MIGHT survive, but.......
You'd def wanna wear safety glasses :-P
That is a SPEED DEMON! Great vlog, thanks for sharing
Some times you come across a thing so absurdly awesome all you can do is giggle. This is one of those things.
Amazing.. very good pilot..
Great example of the Doppler effect too!
I think that sound is the prop breaking the sound barrier.
Wow that was awesome! I never seen an rc plane so fast! Thanks.
I'm imagining piloting this in FPV with dual cameras for VR!!! 🤯
I thought putting a camera on the front underside would be really neat!
In Worten nicht zu beschreiben!!!!!!⭐️⭐️⭐️⭐️⭐️
Good grief, that is speed! Simply fantastic!
Thanks a lot for building taping editing uploading and sharing.
The speed of this plane is stunning. No tricks, not a small screamer, just raw scary power.
Outstanding!! Wished that noise could have been recorded in Stereo. Still outstanding!!! 😘
Correction for “Noise”... “Scream”. It is lot better than noise!!👍
Der Piepmatz geht ganz schön ab ! :-D
😂 Den piepmatz möchte ich nicht an Kopf Bekommen
No way 😂
Wieso "no Way" ? X-D
The sound effects coming from that plane are amazing!
It looks like death. But it’s coming towards you so fast it will reach you before the end of this sen....
WT...
And here I'm too afraid to fly my Mavic pro 🤣🤣🤣
That pilot is amazing!!!
Faz S I had gotten back from our local soccer park and had flown my UMX TIMBER and Hawksky for about an hour. I threw them both away after I saw this. It’s not even the same sport....
0:34 - Watch your fingers, dude,,,!
Wonderful pilot and camera man...
Germans build incredible RC planes.
F1 Sound, also wo die Formel 1 noch Formel 1 war
At that speed you would need a good camera and that would be extra weight and gotta change the cg and all that so
Ist aber Formel-E
Sounds really powerful. Put a GPS in it to prove its over 300 mph. It doesn't look like it 😮
A GPS doesn't prove anything. If you rely on max speed readings on a GPS, you are bound to get false displays. A proper 2-gate speed system is needed - or pitot tube.
And secondly, those planes have been thoroughly tested. The title is misleading. The Big Monster has done over 500 kmh, but not with that setup. At 0:18s Ampere Gerd says 424 kmh and I believe him.
How do they measure speed? what instrument?..
The 2-gate speed measurements are taken 200m apart by visual means. It uses cameras and computers connected by a wireless network, similar to what is used in ski jumping and other sports. If you research 'German Speed Cup', you should find more information about it. Be prepared to read and translate some German websites, because that is where you'll find the information.
Their timing traps are better than GPS - this is a flight demo, but for qualified speed runs these guys measure in accordance with FAI rules and regulations, which is plenty good enough for UA-cam captions. This might not be a 500kmh flight, but it's wayyy over 300kmh - the level fly-by is deceiving.
Hey, you're correct. He did say 524. Thanks for catching that. My German isn't so good.
I am amazed anything with a propeller could go that fast
And straight-winged at that.
MIIIIIIIIIR STOCKT DER ATEM WIE GEIL IST DAS DENN BITTE HAMMER JUNGS👍🇩🇪👍🇩🇪👍🇩🇪👍
That sounds so good!
I would say the speed is accurate....well done ...these people don't tell tales... they don't need to do that.
Stephanie Kent
jes, it is all mesured on proven, oficial mesurement....the same as "guinnes rcords" mesured....eventualy not 300 mph in this or every flight, they don't use always new, fresh lipos or the right, most powerful props in training or demonstration flights like in this video... ;-)
yes I understand thats fantastic, a real achievement :)
I cant fly that over my neighborhood lol😆
Hahahaha, scheisse ist das heftig ! Probs an Piloten und Kameramann 👍🏻👍🏻 der Sound ist brutal 😂😂
Wow!! Good pilot and good plane.. A winner.. :) :)
Start watching Video 50sec Later Holy Shit That's Fast Thanks for the upload Thumbs Up Mate
Uauuu flight insanooooo. Marcio from Brazil
One of my all time favorite RC plane videos.

0:35 Damn you could hear the scream of the motor echo 3 times.
madrx2 you have great ears 😁
I heard two
Or good headphones
Lol look at the Guy hair
Easily audible from a few km away.
Great structural design. I thought the wings would come off at that speed. Great piloting and camera work too.
Fantastic RC glider👍👍
Crazy plane 😎

Did anyone noticed the area had a safety net, awesome.

Amazing skills...... to keep that plane in one piece.
Thank you for sharing.
Das muss ja schneller geflogen sein als nur 500 kmh. Das hat sich wie Blitz bewegt! Wunderbar!
This is without a doubt THE best I've seen...should be used for taking images over North Korea
Leighton Bestmann what’s funny is I was actually thinking the exact same thing... Especially after just reading about what knucklehead Kim did today... Im thinking he’s gonna get whacked real soon or if not then something very strange is up.....BUUUUUT that’s a different conversation for a totally different story/video topic, etc... Albeit on this note, Imagine what the M.I.C. has similar to this we don’t even know about... yet or if ever... Damn, now just imagine THAT job for a moment?! lol as in designing/building as well as even just simply flying similar via military grade FPV from 100s or even thousands of miles away. Wicked quiet & greased lightning fast & smooth... It’d be there and gone before anyone on the ground even could much less would realize or even know what the hell just zipped by... & good luck to them or anyone shooting it down. ESPECIALLY if stealth... which of course it’d be.... lol the nerd in me is really coming out here HAhahahaha.
Area 51
I LOVE that sound 😭🤩
Almost broke the sound barrier!🙏
Das Flugzeug: Wuuooaaooo
Ich: Wooooooow!
Impressive. But isn't such wing size too big for this speed?
Not one bit. There are gliders with longer wings going significantly faster than this
Incredible!!! ✈️
That seems faster than most of the jets!
Amazing sound.
The talent that rc pilot has is amazing!!!! Your flying a pixel at that speed and then top it off with a perfect dead stick landing, WOW! Not to mention the camera guy's skill. Great upload...
Brutal speeds wow
When it goes 500km/h but still ends up where it started 3 minutes later.
Der Sound zwischen 1.40-1.50 macht mich süchtig 😛 !!!
Roadrunner has finally outdone himself!
Sounds like an F1 Car passing by at 200 mph
Sounds so damn cool.
Excellent video. Superb piloting skills and great camerawork. The 'plane sounds like a demented Hornet!.
Great camera work
I wonder how many g’s it was pulling on the climb. This is what a plane not limited by a pilot can do.
Hammer!
Geil!
Blattsalat RC nail! !!

We here in AMERIKKKA, are VERY envious!! Good on ya!!😁
charles mathis I put a pulsejet on one of my builds. Judging by the noise, it went supersonic before catastrophically failing.
Ridiculous. And props to the camera man!
My god that thing is FAST 💨!!
Wow I thought this was clickbait but I was wrong holy holy
Moe Gee If this is click bait, reel me in🤣
Sounds amazing best rc plane sound yet
Outstanding Camera Man... & Outstanding Pilot WOW... all we had were U-Line Airplanes in the 70'S
