How will I know how far I'll fly?
I’m high flying and free
There’s a sun rising for me,
There may be cities beyond the roof tops
Oceans beyond the seas
I'll fly out to a faraway sky,
No one has traveled so far
Out to a faraway star
There’s a new world out there,
Coming to find me
Everything’s waiting up ahead
Nothing is behind me,
If I don’t dream,
If I don’t try,
How will I know how far I'll fly?
There may be mountain peaks,
I want to slide down,
There may be rivers fast and wide
I want to ride down.
If I don’t dream,
If I don’t try,
How will I know how far I'll fly.

What is this?
At frist blush , it possibly could be a freight- hauling craft of some type.
With the open area in the center and the four prop set-up seems to indicate this could lift a great weight.
But upon further investigation - it is the latest prototype of the Makani Power, Inc. team -
Experimental Wind Turbine Flying Craft with a potential to invert wind into 20 Kilowatts
- This craft can hover , remaining in sustained directional attitude.
US Hawks discussion thread:
Tony Prentice, hang glider pioneer of UK, offers:
When doing low level testing the skis provided a fail safe allowing a belly landing without damage. Some of the slopes used for testing were very shallow and extended glides in ground effect would bleed off speed leaving insufficient for a full flare stand up landing. The skis also allowed a complete novice (see attached photos) to master the landing without too much drama.
[Note expressed on 8Jan2012 concerning the 1970s explorations.]
In this Safe-Splat project at US Hawks, someone may consider advancing a deployable version of what is seen.
All experimentation invites the highest of safety practices.
No warranty of function or safety is implied in any note in this project.

Tradition of wing running on flatland continues!
test with wings!
==This video http://www.humanbirdwings.net/about/first-test-with-wings/ has been put up by Jarno of his first flight attempts. Some suggestion that the image has been done by computer generated graphics. The quality of the video does seem to diminish during the "flight" sequence. With all the effort shown on the site having just one camera poorly sited to cover the flight would seem rather remiss of his team. Also panning down to the ground at the beginning and end also seems strange. A lot of effort if it is a just a stunt? Tony
==Fun. Part of a loooooonnnnng tradition! Wing running! (WR)

2. Glider-only branch
__2a. Hang glider running practice
__2b. Serious high -performance wing with intent to glide over a flat field for distance.

Reply by Russian observer - Yesterday at 20:01:38 I think that Jarno has chosen a very good concept. While this video does not appear, some of the advantages such an approach are obvious. Previously, it seemed that the main advantage of its design in the management, ease of manufacture with an eccentric drive (well, light weight, thanks to an electric model aircraft engine), and ease of repetition. Like, on the basis of this concept will be able to repeat the followers of other apparatus, but with more powerful engines, enhanced design, etc., that sooner or later lead to the flying pattern. Moreover, the shape (elongation, area, construction of the wings), it could be a machine, quite unlike the wings of Jarno.
But now, after watching the movie, in my view, priorities are shifting. In the foreground is felicity drive. Due to the large elongation and very low amplitude swings, it came out that the carbon fiber spar ending work effectively in an elastic mode (see video). This potentially eliminates the problem of compensation of inertia. A setting of the control software engines with appropriate time delays, we can use this effect and significantly reduced power consumption. Now there certainly drives spinning at a constant power, so when the wing is stalled in the extreme positions, the currents increase and bask in vain engines. But at this point can be engines "off", wait at the expense of the elastic wing spar will be an extreme point, and will return in the opposite direction, and then "turn on" at full capacity for the power mach. And as all this can be done programmatically, but I see no problems in implementation. In the hard drive is a mechanical crank so it would be difficult to focus. And then return the graph cursors current consumption (typically the work of model aircraft engines is being watched by the current, it is their full-time function), by which we can determine in what points need to reduce power.
Another advantage become apparent when tested turned out that due to the large elongation and elastic rails, real strides amplituha was more than a mechanical drive issue in itself. And it was at the end of the wing. Thus, the wings in a similar geometry to lengthen and the amplitude of the swings in fact working as motor glider, only instead of the engine with the propeller thrust is creating end portions of the wings. So on the whole flight should be on the dynamics is similar to a hang glider with motopodveskoy, which is quite acceptable. Center section is created in the main load-bearing function. And because of that up too mahah creates a positive thrust (or negative buoyancy), the center of mass of the apparatus should not be very jerky vertically. This mode is actually reduced to Mach vibration end parts, which so far comes from a long wing to the pilot, may come to naught. Unlike the bird maholetov that make max power only down and up passive, there is a fluctuation of the pilot will be more difficult ... (Although there also has its advantages).
Therefore, the chances of a good and practical flying machine in such a very, very great, IMHO. And we can expect a whole class maholetov just such a plan. In a sense, similar in geometry and mode swings. First to fly in calm weather, well, then to the extent of use of statistics and tests, who knows, maybe in termichku. Then the possibility of self-launching motor and flight between thermals and the thermals themselves in planning with fixed wings, would be an ideal application for this maholeta. Given the electrical nature of engines with a small reserve, but easy-to-home storage, low noise, etc. This is certainly the dream of many people on free hovering flight, without reference to the winches and other airfield infrastructure.
The quality and quantity waver surface aerodynamic forces - these are trifles. The former can improve the frequency of the ribs, with Jarno they are very rare. A second increase engine power, is now available for sale almost four times the power supply (2 * 7 kW = 14 kW instead of the present author used 2 * 2 = 4 kW kW). Weight is not particularly increased and will remain within acceptable limits for the knapsack. The key point - this is a great extension, low amplitude and high frequency of strides strides (or with great force by powerful engines.) And more likely to control dazhkammi eventually reduced to the joystick, which will simply increase or decrease the engine speed as the throttle on the paramotor. And, perhaps, change the frequency differential of the left and right engine to turn. But while the test manual control mahami is what you need. END OF MACHINE TRANSLATION FROM RUSSIAN COMMENT."

Here a rough study from available rigid and fabric hang gliders.
Tarifs - swift light d'aériane en France: planeur rigide décollable à ... (about 25000 $; 12.5 m², 48 kg; about 520 $/kg; about 2000 $/m²)
Parapente.pro : Fun 42 MK2 (Apco / 2011.00 / apcotandem) (about 4900 $; 8.7 kg; about 563 $/kg; about 116 $/m²,best ratio L/D is about 8 or 8.5).Note: for a ram kite the price is two times lower:280 $/kg and 60 $/m²,but for a lesser ratio L/D.
Swift as power kite/m² would be about 6 times Apco (In fact a lesser value because of tether drag). So a 12.5 m² Swift roughly = 1.5 Apco .
In one hand 25000 $ for rigid wing (Swift); and 7350 $ for fabric wing (Apco).
If the duration of rigid wing is more than 3 times (taking account of resistance but also the probability of destruction by crash) the duration of fabric wing it can be preferred for some uses.
