Spencer's World Record 468mph Kinetic100DP flight video!!!

[zapperoni1337]

My Dad is Warren Day, He sent me here. You should seriously think about putting a GoPro on that thing... It will put some extra weight on it, but it would be awesome.

[masso172]

This is basically a bullet that thing could really make some damage if it hit you

[Teamtigerpaw]

Great job Guy's. I think the old term (Adrenalin Rush) might not keep up with this. Maybe Thermonuclear Rush? Keep flying,stay safe and thanks for Posting.

PS Who's getting to 500 first????????????

[Partok81]

I watched this in 720p on a 22 inch screen and still could barely see the plane. The sound that thing makes is like thunder. Wicked. I'd say the camera/radar guy did a great job flying it too considering it isn't his plane. I'd be trembling too! Congrats on the new speed

[gameplayer634]

in this video all im looking at is the village below cuz i cant see the plane

[thatairplaneguy]

I cant see anything

[mspinney203]

I want this video on my X606 phone.

[BluuXP]

@mspinney203

If you read my coments under the video you see that you can download the video at RCSpeeds(dot)com

Chris

[volvotl22]

Speechless....., just listen to it ripping through the air!!!!.

[ehelibuff73]

Only 468? J/K That fucking fast man! I have an old Opus. I've wanted to buy an Extreme 100 or DS 80.

[hunteraceved49]

This vid went viral on Accra

[kingargon14]

@rcspeeds

WoW from 468mp/h, how long did it take to stop?.

[rcspeeds]

@kingargon14

I have a couple of videos that you can see the landing and the flaps work. As soon as you stop DSing the plane will slow down to the hundreds. Then Flaps... The "The incredible ThunderMaster goes 425mph!" on my channel shows a 200"/75lb. plane landing. I catch a “lighter” plane after DSing it in the "NyxAcroSounds@Weldon" video and you can see the flaps work and the landing on the "Take A Dynamic Soaring Ride In The Kinetic" video, (a on-boardDS video)

Chris

[kingargon14]

how did they stop it???

[rcspeeds]

@kingargon14

we use flaps to slow it down just like real airplanes...

[mwilson14]

I'm waiting at any moment to see that flicker of water vabor/condensation over the wings and hear a bang. That is incredible. Hats off to you.

[n3iyr]

Once you have the flight angle perfect, how do you keep the glider tracking right? Is it done with mostly small aileron or rudder adjustments?

[rcspeeds]

@n3iyr

There is no rudder and yes very small corrections. Also, most DS planes that go over 250/300mph have different rates for different speeds.

Chris

[RogerBadgerDSFlyer]

Beautiful video. Time 6:20, Spencer, "405" - Chris, "Oh that's it dude, that's all I want." I love it, that made me laugh. That's fast! That would be enough for me too Chris! Nice work Spencer, as always.

Best regards, Steve Rainbow

[JackBender]

Tremendous velocity ! Over Mach 0.6 ! Hats down !

On a side note, could you American people begin to use the metric system of units ? It would be a smart move because you are posting videos on YouTube and most of the views come from outside of the USA if I were to guess.

Only Burma, Liberia, and United States have not begun the metrication process. Don't be the last country in the world to make that change... just a wise advice...

[xterminatorSD]

Nice- Yall come see my videos for the very 1st Slopeless and Windless dsing ever posted online to date...

[TheAndrewz1234]

Oh my god, this is crazy.... Congrats on world record!

[rudy8278]

Simply amazing! How did you damp the wind noise on your camera? Which camera?

[rcspeeds]

@rudy8278

When I look down at the Radar Gun at 3:40+++ you can see how. I have an HD-Sound recorder separate from the camera. It has a wind guard on it too. The sound and the video are compiled later. Otherwise the sound isn't that good. One more thing the recorder is on the backside of the hill where there isn't as much wind. Even during the launch the sound was recorded in the lee of the wind...

[rudiratte1]

thumbs up if you couldnt see the plane most of the time

[MrGenebets]

nice camera work

[punkrocker1984]

No anger, but I can´t see a shit. Impressive sound though...

[tahoeskiier]

Does the carbon fiber produce a good reflection for the rada gun? I would imagine it does since it blocks rx signals from leaving the plane.

[rcspeeds]

@tahoeskiier

Yea, I understand, its hard to see the plane when it's going over 400 but if you read the original text below the video you can download the original file at rcspeeds(dot)com. THen at1080P, if watched on a decent computer you can see it,,, sorry bout that. Sounds much better too without the YouTube compression.

Chris

[tahoeskiier]

@rcspeeds

What does reading the original text or downloading the video have to do with me asking if the carbon fiber fuselage produce a good echo for the radar gun? I can see the plane just fine in the video. No need to load the other one

[rcspeeds]

@tahoeskiier

Sorry TahoeSkiier, I responded to the wrong comment. No these planes are hard to get on the radar we have tried many types of reflectors, (corner, metal under the paint, in the paint and small strands of metallic fibers) to enhance reflection. They are quite stealthy. We think more because of shape than Carbon.

[awilliams1701]

@rcspeeds even at 1080p its still hard to see, but I did see it. Its only there for 1 frame at a time.

[rcspeeds]

@awilliams1701

I guess I can see it going all the way around the circuit because I flew the plane for the second half of that video and therefor I know where it's going to be, or supposed to be. Sorry you can't see it but its there to see for many frames at a time. The thing about this kind of flying, we didn't know it was all going to come together for this flight. I also could use a better camera to catch the action and yea, it's moving over 450mph, so it's pretty tuff.

[AVKtt]

Who known -there is  "miles" meant as "nautical miles" or statute?

[sll914]

@AVKtt

The speed is measured in statute miles (5,280ft) per hour or 753km/hr...

[AVKtt]

There are interest to purchase 100", but autor not set price )))

[sll914]

@AVKtt

You can contact spencer via email at: spencer@DSKinetic d o t com

[crunchycrispybacon]

What a coincidence; I grew up in riverside and did plenty of messin' around in those thar hills, and it also happens to be that I just finished a glider kit I had started 3 years earlier--a dynaflite talon lol. I imagine when it's not santa anna winds out there the SW's keep things nice?

Its cool that you guys broke the world record (for now) there! One of the few good remaining things about IE these days, plentiful windy slopes!

[Yafra46]

753.17 km/h .... Woow :)

[oakleymac1]

That's a real achievement well done your on the cutting edge of what can be done with an rc plane are you going to try to go faster by improving your design ? I'm amazed at how fast you got that thing to go incredible the g force must be massive on that wing it would be cool to try and hook up a g mometer

[rcspeeds]

@oakleymac1

There was a g meter and it maxed out just under a hundred G's. The data is available on a RCGroups thread. You can get to the thread by searching Google with the words, (Kinetic world record 468 data). It will be the first search result top of the page.

[GEARSCOMBATANT1]

How do you recover the plane without destroying it?

[rcspeeds]

@GEARSCOMBATANT1

We use flaps to slow the plane down. If you got to my channel and view other videos you can see landings. In fact in one video, (NyxAcroSounds@Weldon.mov) I catch a lighter DS plane and in another, (The incredible ThunderMaster goes 425mph!!) you can see a 77lb/200” plane first fly up too 425mph then land. Both landings you can see the flaps are deployed and both videos are taken at the same site.

Chris

[ericunderscores]

Honestly, how do you control it? how do you keep it in a loop pattern so easily? And with no engine how does it create thrust? Sorry if it's obvious, it's just really interesting.

[rcspeeds]

@ericunderscores

It's much easier to see in person. The bright florescent helps too ears play a big part. It's helps when you the pilot too. In other word you expect the plane to do something and look for the plane in that part of the sky. AND the Bigger the better for vision!! Check out the “The Incredible ThunderMaster” video on my Channel. For an explanation of Dynamic Soaring, the technique used to gain this speed got to RCSPEEDS*com/information/dynam­ic soaring.

[Hayabusa2049]

@rcspeeds Thats cool. But it would suck to crash that into something or some1 at over 400MPH !  :(

[triforce209]

I can't see it!!



[rcspeeds]

@triforce209

Sorry about that but if you watch the video in High Resolution you should see it. You can go to the website that tracks Dynamic Soaring planes, pilots, and speeds and download the HD original video it's a much better view and the sound is much better too. The name of the web page is rcspeeds*com.

The Kinetic 100 DP (Fastest RC Plane in the world,,, except the military’) web page link...

Just find the fastest plane on RCSPEEDS and the HD video is on that plane…

[jwdjr2004]

can you put a camera in the nose?

[rcspeeds]

@jwdjr2004

Sorry i posted a reply to @russ130657 that was meant for you, we posted a camera on the t-tail and it's on my rcspeeds channel...

[thadopeman]

you should mount the radar gun on the helmet as well

[00RSZEX]

i wonder how fast some of the 'no-reads' were.  Man thats fast.

[rcspeeds]

@00RSZEX

Go to my channel and watch the video where I put a small Key Chain camera on the horizontal stabilizer which is located up high on the T-tail. The name of the video is, “Take A Dynamic Soaring Ride In The Kinetic”. It's a little crazy but check it out...

[rcspeeds]

@00RSZEX I would think pretty close to 500mph... Because of the way Dynamic Soaring works the actually air speed is faster than the ground speed. We use very accurate radar to measuer the speed of the airplane relative to us but the plane comes up the ridge and slams into a 70mph head wind, that day, which adds more speed. Figure that the plane had an air speed of about 540mph or so at some point in that fight.

[coma13794]

When I left norcal for the east coast 6 years ago, we were all amazed when Craig T and Dave R were fixin' to bust 200mph. It is utterly staggering how far things have come. I got to 165mph with a stock Wizard at Coyote Hills (with 15-20mph winds), and that was enough to get my heart racing.

I absolutely cannot fathom the reflexes, coordination and concentration required to fly at this level. You guys are amazing.

It's also a feat of engineering that the plane hasn't turned into confetti.

[mlcoo17]

THIS is the kind of stuff You Tube was meant for. I was transfixed to my monitor watching and LISTENING to the glider crack through the air. Would I be correct in quessing that there is some danger involved in these feats. I mean, damn, at 468MPH the kinetic energy of that glider would be fatal if it hit you in the chest, neck or head, right ? My math sucks, but it's mass x velocity squared, right ? Some smart soul out there should figure out the foot/lbs. of energy ( as is done for bullets ).

[Inferalanding]

An amazing feat. Those things just don't look stout enough to handle that kind of speed.Very streamlined fuselage but when you think of a model going so fast you think of a short stouter wing, possible highly swept. If a hawk or vulture popped over the ridge at the wrong time it could get real messy.

[hamburgrd]

What a fantastic vid. You guys are the talk of the town.

[BikeMeAustin]

Very cool, congrats guys! Dude over on another thread just insisting that's it's impossible to go faster than the wind is blowing-tried to direct him here but not sure if he watched or not.

[turdsurfer]

Amazing! What I just don't get is if this is really dynamic soaring as explained at Dynamic Soaring 101 where there are 2 different wind streams merging together, or is it just a matter of flying loops in a single strong mountain wind.

[sll914]

@turdsurfer

This is 'proper' DS... The different airmasses are the 65mph wind on the front of the hill versus the approximately still air on the back side of the hill. In the video, whenever we are DSing, you're looking at the back of the hill at the still air. The launch shows the front side of the hill where the wind is. Hope this helps.

[ChrisTechTV]

There needs to be an onboard camera on this thing!!

[sll914]

@ChrisTechTV

search 'dynamic soaring on board video' here on Youtube and you'll see just that. An Opus around 250mph at Weldon, ca...

[russ130657]

Watched this over and over, It really is incredible. A real credit to you guys who are seriously "pushing the envelope". What is the all up weight of the plane? I will understand if it is a secret.

Russ

[rcspeeds]

@russ130657

Hey Russ, sorry didn't notice your questions. The Kinetic 240-300oz+!

[askii3]

I wonder what kind of airspeeds are achieved around the flight path? If it's going 468 relative to the observer and climbs into the horizontal wind shear that goes from 0 to 60+ component then the TAS is easily over 500mph, even with the plane entering the shear at an angle. Time to begin designing for supersonic flow! lol awesome

[rcspeeds]

@askii3

That was addressed by Dr. Mark Drela's, (MIT Professor). Spencer's guess is that if the gun could have caught the two passes after the 468mph pass, we'd have seen around 480mph. Combine that with Mark Drela's plot of ground speed and it reveals that the probable max groundspeed was over 520mph on the un-radared dive in part of the circuit. Air speed probably something around 550mph...

More information and Dr Drela's pdf file: Search "rcgroups Dynamic Soaring 468 world record"

[russ130657]

Absolutely amazing, 500 is definetly around the corner, we have tried a bit of DS'ing, but no slopes around Durban are suitable, that you can drive to anyway. What amazes me is how strong these planes are, I notice there is no footage of the planes landing!

[rcspeeds]

@russ130657

I know I blew it, The plane landed very softly in the grass. I was too amped up on my 405mph flight and was trying to get a picture of the radar gun when Spencer landed. You can see a picture of me holding the plane and a 405 on the radar gun on rcgroups .com... You can learn a lot more about the flight, see the results of the onboard data tracker and more.

[Magoebaskloof]

How accurate is the speed determined? Radar gun needs to be in straight line. For instance a car comes down straight line th radar flags it, and then it measures the time in between the flagging. Are these gliders measured between 2 points and time???? Just a question

[sll914]

@Magoebaskloof

Every radar gun that I've ever seen calculates speed by measuring the doppler shift of the returned radar signal. It is very consistent, very accurate and any error from misalignment (called cosine error by radar guys) only lessens the measured speed. It is not possible to measure a speed in excess of the objects true speed. It is consistent and accurate enough to hold up in traffic court and allow municipalities to collect from speeders...

[rcspeeds]

@Magoebaskloof

sll914 had a great answer for you he's the guy that flew the plane to 468mph I flew the plane to 405. It's actually pretty hard to get the top speed. What you have to do is aim the gun where you think the plane will be when it's pointing at you at the lower point in the circuit. The objective is to get the plane at the tangent of the circle and pointing at the gunner so you can get the best speed. Check out rcspeeds.com and rcgroups.com to learn more about the radar guns.

[sensiblenick]

... and then to pass the record-breaking plane over to your mate to have a blast: that's why I love this hobby :o) Congrats on a the 405PB and the new Record! :D

[3dfoamies]

How do you even see the thing. I can barely see the glider in the video. Cool video!!!!!!!!!

[rcspeeds]

It’s much easier to see when you're standing there, well as long as you're not shaking too much... We were both shaking and needed to take a break just to calm down. If you look at the top of the page, find my comments you will see on the bottom a link to Spencer’s, (the first 468mph pilot), page on rcspeeds.com and there you can download the original very high definition version. If you watch the original on a good computer with a big screen and a good video card you'll see a lot more.

[Savvrawr]

Pure awesomeness!!! 500 MPH looks like it will be soon!!

Congrats on the 468!!
