On February 2, 2011 Spencer Lisenby flew his own design the Kinetic 100 DP to 468mph setting a new world record at Norco California in winds gusting over 65mph.
Here is a video compilation part of that flight. The radar gunner, Chris Bosley also flew the plane and his flight is included in the second half of the video. Unfortunately in the second portion of the flight the plane is more visible than the world record passes for three reasons. One the plane is flown less aggressively at a much slower rate, 405mph (borrowed plane :o) two, the second pilot is wearing a helmet camera so the camera is naturally following the plane and nobody fly's as well as Spencer. During the record passes the radar gunner was more concerned about getting the speed on radar and not thinking about filming the flight so there's a bit of quick camera movement.
EDIT:
PLEASE DOWN LOAD THE ORIGINAL VIDEO AT: rcspeeds.com/pilot.aspx?p=74
I understand during Spencer's flight many RU-vid viewers can't see the plane and wish they could. If you like the video and would like to see the plane carving up every lap try downloading the original HD video and viewing it on a lage computer screen!

If I recall correctly, their loop allows them to get lifted up via wind being compressed against the hill (the plane can gain altitude for free) before moving away from the hill / updraft, and gliding at a steep descent to gain speed. Then once at the bottom of it's drop, it turns back over to the hill and gets boosted up again. This all happens in one big, smooth loop.

INCREDIBLE !! That craft is incredibly strong and the piloting SMOOTH to not plow the hill - WELL DONE !! This is a fantastic effort - the sound of it ripping through the air is fantastic !!

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.

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

How the heck did that thing stay together! No wing or control surface flutter at all! Very impressive!!! Congratulations!
@RobinCernyMitSuffix
@RobinCernyMitSuffix 6 лет назад
because most of the weight is in the wingtips, and the whole wing and servo assembly is optimized against fluttering

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.
@sterby1
@sterby1 11 лет назад
The plane travels in circles BEHIND the peak, so on the upper part of the circle the wind is adding speed to the plane, much like a sail on a sailboat. When the plane continues the circle somewhere below the level of the peak the wind calms down and it flies in still air. (There is a turbulent layer and some turbulences, but that doesn't matter here) In the still air the plane can turn with precise conrol without losing any speed, continuing upwards to reach the wind zone and the cycle continues

@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

Congratulations!!! absolutely amazing speed record. thanks for sharing. when I think of all the money I have spent to get my powered planes moving and only tapped 130 mph, my jaw just dropped watching this. I have no idea how you two were able to control the plane at the speed and in that wind. just one little wing dip and BOOM! ps whats with the dislikes?

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?

@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 RU-vid compression. Chris

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!

i'm not one of the ones saying that gps data should be used for this. i understand why it would not be accurate. what is it called when the gps data is corrected by inertial reference systems, like accelerometer data? a friend who used to work aboard a nucular sub explained a similar system, where inertial references were used exclusively underneath the polar ice cap for navigation/positioning.

@JohanVanTonder
@JohanVanTonder 13 лет назад
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
@p1ayaone

@ElGuitard0
@ElGuitard0 12 лет назад
I think the reason shes going 701 Kph is because shes saoring up n down in a nearly vertical circle, as shown in her video and she appears to be making tighter revolutions with each pass until the glider is literally catching up with its own tail! Most likely that kind of speed is being obtained because the build-up and release of energy is happening at much faster rate.

So, the lead is to keep the wings from snapping off from the weight of the fuselage? Wow! I was wondering why in a frame at 4:15 why the wings were not arcing up. Looked like they were flat. Fantastic idea! I suppose no matter how tough the wings were constructed, in turns that tight, it would snap them right off. Now I understand how they stay so flat during the turn.

@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...

@davidwebber2888
@davidwebber2888 8 лет назад
Are you using a radar to read the speed? Its very hard/impossible to see this speed machine but if you are using radar i am sure you are aware that it only gives acurate info if the object is coming straight at you or directly away from you? Its just it appears as though the reading is being taken side to side. Have to say great flying and a hell of a beast youve made there.

@alohadotmorgan
@alohadotmorgan 10 лет назад
WOW!! Great video of a great record! I did the backwards math - speed in feet/sec, approximately 3 sec per pass) and got a diameter of 655 ft for the roughly circular flight path. Is that about right?
@Fuggs70
@Fuggs70 10 лет назад
A 655ft diameter seems reasonable from what I could see in the video. When I could even see the plane, of course. Assuming the camera had a NTSC-like framerate, ~30 frames a second is pretty much going to limit the view of a motherfucking natural-energy-sucking speed demon from hell contraption going 468mph *maybe* 1 frame to be captured. The thing is seriously so fast it's practically invisible to that camera. This is exactly the principle on which The Flash operates. This glider is like actual superhero shit, on video. But it has the superpower of invisibility against cellphone cameras, causing a video taken by one to be a paradox. Bow, mortal. Edit: The flightpath may be more elliptical than circular, so the backwards math might need calculus. But 655ft across is something I'd totally believe based on the video perspective and 6-7 foot-ish wingspan.

That is an ingenious method. So, the fuse is just along for the ride! Ha ha! After thinking about it, I understand why a GPS wont work either.. the refresh rate being too slow for such tight circles.

@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

The Lead; it also adds weight, (we want the planes to be heavy, to have a high wing loading) and since weight is along the wing the center of mass will be at some distance from the fuse,,, Helps to increase Moment of inertia...
@3dfoamies

How do you even see the thing. I can barely see the glider in the video. Cool video!!!!!!!!!
@rcspeeds
@rcspeeds 13 лет назад
@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"
