- Strong Santa Ana conditions on Jan 19 2021 provided enough wind for Spencer Lisenby to bring the dynamic soaring speed record back to its birthplace of Parker Mountain, CA. Wind gusted to 65mph and temps were 45-50F. This flight beat the previous record set in 2018 at Bird Spring Pass by only 3mph. Filmed with a Gopro on my head while flying. Best viewed on a large screen with high resolution. Max acceleration estimated around 90-100G.

@@stevie1246 and the ball is going towards youre face
Quite efficient usage of free available energy ;) :D :)
oh, so the camera follows the plane?
I thought it is onboard camera and they didn't launch it yet
How in the heck can a human being control something going so fast so close to the ground manually? It is even more amazing to me that it doesn't just crash into the ground.
it's only minor corrections every loop; it's not entering and exiting multiple maneuvers, just the loop is established and keeps getting boosted. I noticed sometimes the loop ended up higher. the amount of control deflection to work safely at those speeds must be miniscule
Here's a video that happens to show the stick movements while DSing at 485mph. You can see the rythmic inputs on every lap plus a bunch of random corrections due to turbulence...Turbulent air is constantly trying to throw you off course...

its only a matter of time before one hits a human....also the jets are in the same league for danger.
Shit man, it took me a whole minute to realise what the hell was happening
@TH-cam Is Dying Painfully he's looking for thetumbnail pretty much
How did that thing go that fast ? I’m confused it looks like a glider and I don’t think it has any engine how is generating thrust ? Is it simply by wind speed ? Wtf
@@hemendraravi4787yes, it dips into a strong wind to gain speed, then goes out of it and flies back to the starting point to do it again
Dear God just back the camera off a bit and stop getting us seasick
Holy shit!
Yeah the camera work was a bit much
I laughed at this comment after i finished vomiting
Apparently, we're watching the video from the camera attached to the pilot's head, hence all the back and forth, as he tracks the glider.
65mph winds, the road they are on is on a thin ridge with no protection no place up there to hide - so now spielberg here
DSS is so crazy man, the fact that you can go this fast with no added propulsion is ridiculous, if someone told me and I hadn`t seen it on video or been at any DSS sessions, I`d probably call BS lol, it`s just nuts :D
Btw, the sound in person is insane..
Quite efficient usage of free available energy ;) :D :)
Remember, the highest groundspeed is happening on the downhill pass, just before the lull section. Also, factor in the windspeed at the uphill transition (+65mph). Getting close to supersonic. Great work.
That would be cool breaking the sound barrier with a glider.
@@billdonaldson7546 Unfortunately physics tells us that long and striaght wing going at transonic speed is really, really, really bad, and that 548mph is right at the transonic speed ~.7 mach. So the glider is unbelievably impressive already.
The amount of G-Force has never been so Huge!
The hamster inside wore a G-Suit.
About 120g
How the Hell does that thing stay in one piece at that rediculous speed???!!! It's almost traveling at the speed of sound! Especially in that small radius continued loop!
Crazy!!!

The impressive part is getting it back.
lol he's full flaps and the thing doesn't want to set down
He just flies it in circles until it vaporizes.
@@MrCarnutbill67 planes have a speed rating called Vne, or "Velocity, Never Exceed'. In Dynamic soaring, the shorthand for this is "Puff speed".
@@wayneledzian5342 The thing about limits and engineering, Ratings can always be pushed, but you'll never get an engineer to tell you how much you can get away with.
@@wayneledzian5342 Would that be the *poof* speed?
"Wow, that's amazing! How does it land?!?"
"Oh, easy. Catch."
The sound it makes is absolutely insane.. I actually looked Spencer up after hearing a spacecraft engineer named Andrew Higgins mention him during an interview he was having where he was discussing the idea of using dynamic soaring of solar winds as a propulsion method for interstellar travel.. It was pretty mind blowing..
Nice job guys. For anyone who hasn't stood by in person during a DS flight, it's a lot more spectacular than what the video shows....and the video is amazing. I've seen gliders turned into carbon fiber dust is a split second when the pilots timing is off by a split second. Just to get the plane back in one piece is a test of skill.
woweeee almost mach 1 speed there. i wanted to see how you slowed it down. maybe post that clip too :D amazing control
They're a little higher than sea level, so not as close as it might seem.
Mach 1 is 767 miles per hour.. define almost😂
@@aashisheapen8230 isn't it about 200moh away still, at sea level? That's another 30% or so faster. I get that "almost" is a subjective word. I wouldn't use almost too mean I'm 30% from my goal.
Hey dude just subbed to you looks like you have some good content
@@daniellemichael2619 Thank you so much. I have just been on youtube for 13+ years. not too long :D hahaha only 4600+ videos and increasing
I continue to be amazed by your teams progress. Dynamic soaring is absolutely nuts!
Im 50 and been around RC all my life. This is the most insane variant I have seen yet! Bloody awesome.
Is there some sort of mid air tennis match that we aren't aware of that they're watching with that camera?🤔
When steering the plane straight ahead for a second means it immediately flies out of sight.
Pretty cool that the fastest RC plane is a glider WITHOUT a motor!
Those complaining about the moving video. With it held still you STILL wouldn't see a damn thing. You'd need 4k video at 120fps to even get a chance of capturing some good frames.
Just waiting for the day we get a rc plane faster than the speed of sound
Honestly, probably won't be too long, this is about mach 0.9 or something
Uhh bruh we already have one
We have many...they are common...
Transonic area is very nasty. Drag increase rapidly near mach 1 and so does other areodynamics. It will be extremely hard to reach mach 0.9 or above.
@@PaleOrchid maybe it's possible with some other design
However this came to my mind: Imagine u were a pilot back in ww2 and seeing this thing flying by 😂
I would piss myself
Toward the end of the war the p51 could achieve speeds of 400mph ish, thats high altitude with little air resistance. Down at that altitude in the video id say it could do 350, which is still terrifying
even the me262 is scared
Me262s max speed is 540mph at that altitude now that ur saying imagine but let’s imagine how they would have felt seeing super fast machines which weird buzzing noise and those huge 30mm cannons it must be real scary
I like the vid where the exact moment the guy launches his glider, he says "Oh, no! I forgot to turn it on!!" Then down the hill he went. And it was way down, too.
top clip
I don’t even see how a foam carbon fiber covered wing could stand up to these forces. Off the charts...
i think it's just CF. servos begging for mercy
I was thinking the same. The g forces must be amazing. Would love to have a sensor record the max g load.
@@aafjeyakubu5124 Max G recorded on the predecessor to this aircraft was 120G, which is the maximum the sensor could record. They routinely cruise at 80 to 100 G continuous turn. It is covered in this presentation from 2017 th-cam.com/video/nv7-YM4wno8/w-d-xo.html
@@harryspeakup8452 I honestly didn't think I was going to watch the whole video. I was wrong. Unbelievable!
the wings on these are so strong, a grown man can stand in the middle while the sides are beeing supported on each side.
That sound it makes...it’s AWESOME!!! I love it!
Very impressive stick skills to keep this thing from just smashing into the mountain side
Wow! The camera was moving even faster!
The pilot wore the camera on his head.
In the groove Spencer. Your an amazing pilot. Congrats!
I've seen loads of videos of RC planes (mainly warbirds/airliners and such) coming apart at way less speeds. This thing is amazing!
Congratulations! I no longer think that dynamic soaring appropriately describes this type of flying. Dynamic, yes, but soaring? Any suggestions? Also, pat on the back for your hand, thumb/eye co-ordination. The stress on the airframe must be incredible! Congratulations, again. I truly am in awe!
about 120G s if I read that right
At this point it feels like we've found a glitch in fluid dynamics and we're just exploiting the hell out of it.
@@StaK_1980 120 G's is incredible. 1Kg turns into 120!!. Some mighty fine engineering as well as physical dexterity for flying at these incredible speeds. Like your handle, I live on the same island as the devil.
@@Hyperious_in_the_air Glitch, or very smart engineering. Magic!!!
This absolutely blew my mind! The fastest remote jet plane is not as fast! So I dug deeper into the physics of this and that is mind blowing as well.
Funny thing is I was amazed by the camera operator being able to track the plane so well, only to find the comments all about how they think the camera operator was the problem! I was also struck by how much quieter this plane is from previous ones even while going faster. Did you find and fix some previous source of drag? The winds that day in the City were nuts. You guys must have been ready to drop everything to catch this rare opportunity. Congratulations! Please make a video documenting the whole thing. I want to know all about the project and your plans.
Melinda Green ... never knew Dynamic Soaring existed until now. At first I thought this must be fake (speeded up video with normal speed sound). Then I watched his 2017 video. I’m impressed by this as much as Elon’s starship. Truly amazing engineering
@@douginorlando6260 It's crazy amounts of high-tech and artistry. I mean they're building to perform at a constant 100 Gs. I think they even have trouble getting paint stay in place. I was near a similar plane once and I have no desire to do that again. It's truly frightening. Safety aside, one twitch and you plow into the hill. At 800 feet per second I would also worry about losing it in the sky.
not just any RC speed record. The fact that its just a GLIDER makes it even more nuts!
In the hobbyist segment, such is faster than any RC aircraft with a motor. Even those with jets or small booster rockets are still slower. If you want faster remote piloted aircraft you'd have to look to something government owned, which then tends to be military aircraft or drones.
Problem is more that you have to see and control it. Flying circles needs rudder deflection and rudder deflection creates drag. So hard to get supersonic that way.
Put stub wings onto a rocket will easily get you supersonic, but it will more or less fly in a straight line and might be out of sight soon. There are numerous supersonic hobby rockets out there.
Man what kind of G forces is this thing hitting. Its amazing how it stays together with so much wing loading on a 2m wingspan
90 gs
@@mike3000ization incredible!
The wing was not cheap :) He did a presentation on the problems they faced building a plane that don't explode.
dozens
I'm amazed at how that thing holds up to the extreme g force 😲
Maybe most of it's weight is in it's wings. In that case extreme g force (as I estimated ~70g if it went perfect circles, otherwise more than that) doesn't involve extreme stress, because the support is evenly distributed over it's entire surface.
@@Zilahi-Branyi_Laszlo Exactly, they had to put weight on the wing at the time they were always breaking the wing in half at high speeds. Highly recommended talk: th-cam.com/video/nv7-YM4wno8/w-d-xo.html by Spencer (the pilot in this video).
He said it was a carbon fiber epoxy, and it's doing over 100g's, easy.
881,921Km/h = 548mph Information for rest of the World ;-)
Or is it 548,000 mph. . . just kidding 😁
Yes except England we still use mph mostly 😂😸😂
That this is all generated by a wind speed that is wayyyyy less than 100mph is amazing. Sometimes there is such a thing as a free lunch assuming you like to eat speed sandwhiches
Keep up with the development and one day we may hear the sharp crack of the aircraft's passage as it achieves supersonic flight.
That crackle you hear on every pass is the upper surface of the wing going transonic.
@@crustygrognard7403 actually, I think that may be the sound of flow separation. it's moving so goddamn fast and has such a high angle of attack that it might be causing vacuum regions to form on the top side of the wing for milliseconds before collapsing from the outside pressure.
Almost like how a propeller will produce cavitation when spun too fast.
@@Hyperious_in_the_air I was wrong, it wasnt transonic. The local airflow on the upper surface of the wing was in excess of mach 1.25 th-cam.com/video/nv7-YM4wno8/w-d-xo.html at 35 minutes in there is a plot of the airspeed over the wing.
An incredible aircraft with an equally incredible pilot. I could barely see it. I can't imagine flying it. Nice
Wished the camera man kept the camera steady instead of whipping it back and forth like that. Can barely see the plane as is without him moving it
It was filmed with my Gopro on my head while flying...
How's your neck?

When I was watching I kept wondering if you had some genius cameraman that was good at tracking it visually. Thanks for the comment, it answers my question. The pilot knows better than anyone where the plane is. ;-)

@@sll914 Could consider running image stabilisation on this video, although I'm not sure if it will pick up the plane on the downhill leg
Looks like a 3 second Clip that is looped and speeded up every round :D
Exactly what I thought. It doesn’t feel right how the video was. And I know that modern avionics in rcs are amazing but to go 540mph with only a glider and no jet engine is impossible to comprehend
@@3Dmaker12 Look up dynamic soaring, it's not the only one of it's kind.
You can clearly see the gliders route change so your 3 second loop theory is busted.

Congratulations Spencer! With love, Ken
I didn't even know dynamic soaring was a thing, might have to get a rc plane now xD
Be prepared to shell out several grand to get one similar. 😉
@@wordreet As I've never flown a plane I think I'll just start small and learn to fly before I try something that does 880km/h :O
@@KalLanPIDT Good luck my dude, trainer planes can be had pretty cheap and are easy-ish to fly. You can buy ones with stabilisation electronics built in, or just go for cheap and basic. But I do recommend trying an RC simulator first. I did 8 years ago, and it helped me to start.
@@wordreet Great tip, I can crash without losing anything but patience hehe thanks :)
@@KalLanPIDT Go spend $150 on a carbon cub s2 from Horizon Hobbies, that will get you everything you need to fly,extra batteries are like 6 bucks, it gets you flying, I started there last year, now I own several large planes and a simulator... lots of fun
I am surprised it doesn't break apart.
I am also curious as to the G forces ?
And whether it is carbon fiber ?
( AND - if you're going to all this trouble and doing a world record thing and videotaping it for broadcast - one might think that a person would bring a camera with a mic WIND SCREEN. )
In order
-some designs have been known to shatter once they exeed there desighned speed envelopes.
-The G's for ghis flight have been calculated at between 60-100+G's
-Yes it is built verry heavy and very strong out of carbon fiber. +-10lbs
-The camera is a gopro straped to the pilots head, if it weren't it would be even harder to follow whats happening (its been tried)
@sll914 Congrats and super happy Parker holds the record again. Seeing this makes me want to get back into it. I had one of your early 60". This sport is luck to have an engineer like you pushing boundaries! Never stop and post more videos!
How does one control such a fast rc plane, a motorless one, nonetheless.

You can try it in a simulator. I'm not very good at it, but a couple hours of practice and you could start to get the hang of it. A lot of it is just timing the elevator inputs.
Practice. Takes a long time to go that fast
@T Hebert I think that would only work with ground based optical positioning systems like how they use for those super fuckin stable Drone flight demonstrations the *ETH Zürich* keeps pumping out every once in a while. Everything else - like commercially available GPS positioning systems for model aircrafts, at those speeds and this close to the ground, would most likely lead you to a fine for littering the ground with shrapnel.
Wow, that was awesome, congrats! I had some great hang gliding flights from Parker Mountain 1985-1987 when I lived in the Antelope Valley.
Is it true about the hang glider that launched off parker and flew to Long Beach violating Van nuys and lax airspace and was arrested when he landed?
That story was going around back then
I love how this *glider* is faster than both the nitro & jet powered RC planes!
The airflow over the wing must be reaching transonic in places.
Actually what airflow over wing, this thing is just riding the wind that get accelerated over the top.
@@Sadik15B if there was no airflow it wouldn’t fly full stop
@@neilmchardy9061 nevermind one day u will understand

Quite astounding! Spectacular skills!
Jaaaames hi lol
The Camera was going for a World Record too.😂🤣
Great achievement guys! Love the sound as it rips in and out of transonic flight.
W O W - Amazing - You have big balls - Congratulations!
Keep those records coming Spencer proud of you man
I should have paid more attention to my science classes in school cause I am clueless as to how they achieve these speeds. Simply amazing.
never hold a camera again. just barfed all over my lounge suit.
I was getting motion sickness for real. could not finish
Thanks. For trying to further the rest of us.
Let me know when they break the sound barrier!
It's coming
Thanks for showing landing. Congrats
I did not even know this was a thing but im impressed for sure..!!
Imagine the amount of g's on that thing
Quite efficient usage of free available energy ;) :D :)
90-100G ... Just like that.. What a glider, and what a pilot (even while not on board, he wouldn´t like it anyway).. Amazed. Was there an on board cam ?
id really like to see a full video showing entering into the loop and slowing down for landing
There are other DS videos which show all this. Search for "Weldon Dynamic Soaring Experience" or "369mph PB on Dynamic 130" to see flights with launch, entry into DS and landing. Obviously slower than record speeds, but they were made specifically to show the whole sequence.
It's been over 2 years since this mighty record.. Any update on any newer attempts at upping this further?
Got up to 564mph in February...

The heck with the speed record, how about flying the dam thing and the camera man who was able to film parts of record. I fly RC, and I am curious to know he flys his plane. His control surfaces must have the ability to locked into place and the control surface moments so small you could hardly tell they move?
Moe pow it's most likely a tether plane
@@gr4phite776 You obviously don't understand the principles of dynamic soaring. No, it's not tethered. It doesn't even have a motor.
Sorarse I was uniformed.
Congrats! This is extremely difficult to do, pilot makes it look easy.
I'll bet the crashes of RC aircraft used in dynamic soaring are EPIC. And leave no readily identifiable parts.
Gave me salvia flashbacks watching what looks like the video just looping
How do the wings stay on going that fast. Incredible
Agreed strong wings.
He said it was a carbon fiber epoxy, and it's doing over 100g's, easy.
How is it possible that flimsy looking plane can stay in one piece???? You'd think the G-forces at those speeds would rip that thing into confetti!!! Amazing!!
I’ll take your word for it
All fun in games until it starts heading towards you
A few seconds of commentary would go a long way. Who what how how much etc. Bravo zulu
@Bret Bouder I would ask what the Hell does that have to do with the video, but, honestly, I'm not sure what you said. Slow down and try constructing a coherent sentence.
@Bret Bouder You want to go home and rethink your life.
these guys are cutting edge flyers by any measure. breathtaking.
Makes me wonder how far RC gliders are from breaking mach 1 under wind power?
Maybe in Antarctica during the winter where the wind is fast, the air is thick for the pressure, and the sound speed is lower? Or Mt. Washington during a storm where you get 200+ mph winds?
question from a super basic r/c pilot, wondering, do you set this up with dual rates, and have a metric shit ton of negative expo in the 'warp speed' setting?
Yes you need low rates for high speeds and and higher rates for slow speeds and landing but no expo needed.
Wow, so this uses the speed of the wind to send it, and then it turns back into the wind to go again, eventually building up more and more speed? That's insane.
Parker!!! So awesome...Congrats Spencer!!!
How did this work? Was it powered? What is it made of?
*_See you guys later when this gets recommended_*
That is a very well built plane. Congratulations!
This is impossible. As a glider, where does it get the power to attain that speed while overcoming the drag produced by this wing shape and fly at that speed without ripping the wings off?
There's like a boundary layer with wind-shear coming off the slope. It exploits cutting across that to get all the energy it needs to go that fast from the wind. As far as not ripping the wings off, that depends on the composite materials and design and construction. Seems some RC aircraft in this segment of the hobby can and have shattered into a bunch of little bits either mid-flight or from losing control, but I'm not sure if there's video of it out there.
God forbid you stand back far enough to get the whole flight while actually holding the camera still!

Amazing stuff!
768 to break the speed of sound, I'm not sure human reactions can do that.
thats at sea level and a certain temp. this doesnt fit that criteria
Humans have the reactions for any speed given the right amount of distance and time.
I am stumped at the physics for tapping so much energy from a wind.
en.m.wikipedia.org/wiki/Dynamic_soaring#:~:text=As%20drag%20is%20slowing%20the,wind%20gradient%20lessens%20with%20altitude.
A windmill harvests energy by slowing the wind, thus robbing it of some of its kinetic energy. A dynamic soaring glider does the same by turning hard with its belly to the wind, slowing the air and taking some of its kinetic energy.
I think I heard a few sonic cracks - the air flowing past the wings during the high G turns can become transonic (relative to the plane) and pile up into a shockwave.
Just pick a spot in the middle!! This made me nauseous.
Spencer, awesome man. As a F3J pilot that's only ever watched a F3B speed run I have nothing to compare to this. One thing I want to know, how do you slow it down and not loose it?
keeping it looping above the ridge (not below the edge!) it slowing it down, 10-15 more loops, and after that he´s walking another 1/4 mile to land it . th-cam.com/video/bJbrttj5Ba8/w-d-xo.html th-cam.com/video/bJbrttj5Ba8/w-d-xo.html th-cam.com/video/bJbrttj5Ba8/w-d-xo.html
I saw the plane when released, then nothing until it came back. Figured it was lying in a heap way down below and the photographer was scanning to try and find it. 🙂
Wow, idk what that plane is made out of, but I'd be insanely curious to know how many G's it was pulling there
Edit: it's in the description... 100 G's... fucking insane... now my next question is how much the plane weighs, because those wings were holding... a LOT of force...

An average .45ACP 230gr bullet from a 1911 will fly about 830fps. That’s 565.8mph! You’re literally controlling a speeding bullet. That’s awesome!
Man it must take an amazing pilot to steer the craft at that speed..
What kind of rates and expo are you rocking too manage this? ! Very very impressive
No expo and about 1.5-2.0mm throw on the ailerons
Definitely transonic on several of those passes. You can hear the cracks of sonic booms on the control surfaces.
