[@charlesmoore5268]

I was there the day Larry flew his glider. My spelling may be wrong but: Klaus Hill, Don Beuch, & Red where there. I believe he only flew it once. :)

[@quadruplane]

Thanks for your memory. Good comment.

[@ocsalt001]

Thank you for sharing.

[@quadruplane]

It took about an hour to rig. I did ridge soar it but never really thermaled it.

[@greyfreeman5537]

Wow, the landings are so nice! So smooth. It looks to me that a little tail piece hits softly, right before the weight of the pilot comes down. And the speed is on the lower side, then, the louvres. So cool!

[@rentatrip1videos]

OK, thank you - this is a real dream, of a ship- back in 1971 we used to draw cartoons of HG's like this! wow what a perfectly balanced unit!

[@quadruplane]

That is Klaus Hill, designer of the Mountain Green Sailwing, original Superfloater, Fledgling and others, helping me launch.

[@portnuefflyer]

Epic! I got see Klaus fly his first Hummer.

[@quadruplane]

Yes, the stall speed was low. I don't remember the exact number.

[@charlesmoore1708]

Luckily, I was there that day and enjoyed every things from Don's wind dance to Klaus Hill's attention to detail.

[@dudul69003]

Je me souviens de cette machine .Elle était très délicate à mettre en virage , elle avait tendance à engager...Cela reste quand même une trés belle réalisation....Une oeuvre d'art .

[@MagnarNordal]

What an amazing design! I started to fly Rogallos in 1978 with a glide ratio of 4:1. The Quadruplane must have a better glide ratio despite the myriad of struts and wires.

[@jwserge]

+Magnar Nordal Sorry, what is the glide ratio? (i'm a pot in it :)

[@georgehunter2813]

Four narrow wings in a stack has less induced drag than a single wing of equal area size having fatter tip chord width. The width of the wing tip is a key factor in a wing's flying drag . 8 small wing tips causes less wingtip spill-off swirl drag than two huge wing tips. Rigging drag is a different issue, but obviously matters too as seen by airplanes evolving into monoplanes from bi or tri planes. Flying airspeed range is the key factor in rigging drag. A hangglider with four narrow wings fly very slow, and so the rigging drag is not so critical. In powered high speed flight the rigging drag would overshadow any of the advantage of wingtip layout that the low speed quadraplane enjoys over the fatter winged monoplane.

[@rogerwilco4736]

4 : 1 glide ratio would make for a very heavy landing!

[@yvesbajulaz]

Super cool...

[@overback2328]

I was surprised at the maneuverability of four wings so I believe the 65 pounds! Very well designed but I would hate to repair a crash! Thanks for posting.

God has said in the Quran: { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 ) [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) Quran

[@garrykennedy5484]

That's pretty amazing, but the LD ratio must be horrible? Not sure the extra lift is enough to compensate for the drag. Hmmmm..... Lot of set up and break down. Transport and storage also. Still very cool!!!!!!!!!

[@dimdim6107]

Narrower wingtips with some twist may decrease drag a little, but anyway speed range of this stairway-to-the-sky seems to be very small. But looks perfect, and for the moment of creation flies just awesome - i still remember first -second generation hg wings - dragonfly's wings of free flight pioneers

[@willswingwilly1950]

Wow , I had to watch the video a few times , one would think to see a improved gliding compared with other single surface hang glider constructions at that time , I like the adjust ability of the pilot point of hang in :)

[@wateaman]

Weight control was well managed with this quadwing. Looks like it good performance for 1978 but higher speeds would have increased parasitic drag in a big way.

[@chuanist]

Have to hand it to them: it works well. Wonder if he caught any thermals or did slope soaring?

[@dimitristripakis7364]

Are you sure the weight was only 65 pounds ? Thats amazing! I dream of one such thing laid with PV cells (plenty of area) and an electric motor.

[@izzyplusplusplus1004]

***** That would add a LOT of weight.

[@dimitristripakis7364]

Joash Church There are flexible ones

[@izzyplusplusplus1004]

***** I wonder if that would be enough power. Great idea though!

[@dimitristripakis7364]

Joash Church Im not an expert but I have figured out a decent combination = 10 kW motor, 0,5kWh 20C battery (good for 3 minutes full power), and 500 W PV cells (good to charge the battery in one hour). That is, charge time / powered flight time = 20. But it is plausible and not very expensive. AFAIK, there is no reasonable-cost way to make it run on the PV cells alone (I mean no need to charge).

[@izzyplusplusplus1004]

***** 20 minutes isn't bad. Considering you could simply put it in the sun to recharge, one could get a decent amount of takeoff and landing in one day.

[@christophrufle5811]

+Legend Length the steering is by weightshift? Aber is the C.G.? The wings have any washout?

[@kajlauritzen9765]

Pitch control is weightshift, but if you look closely you will see the rudders for roll control between the two lower wings. (No, I had nothing to do with this wonderfull plane, just read all about it back then. I´ve flown flexwings since 1976).

[@fabiopakk]

Very interesting. It has some control surfaces, doesn't it? How does the pilot control them?

[@BASMEN-ie8fq]

Did it ever go up? i.e.360 in a thermal?

[@sellthefrog8923]

Nice... But why 4 wings?

[@tinolino58]

With 4 wings you have very little induced drag!

[@jerricroft937]

Point of the mountain SLC

[@jlkoelker]

This would win the red bull flugtag

[@huh387]

It has short wings, which wud not lift the person, so, the craft compensates by having multiple wings, multiple wings is equivalent of a big wing in lift power. But that design is very bulky tho, and the maintenance must be hell.

"melhor" is not the word. This model could fly at very low speed with no stall and this is the main problem in modern hang-gliders when you need to land in small fields.

You are Pretty stupid answer. In the video you can see a hang-glider flying at same speed as paraglider. You can not do this with modern hang-gliders. In places where you don't have big fields for landing (like Mallorca) this design is superb.
