Israel considered surveillance UAVs balloon aerodynamic stability

The other day I was reading on a design by some students in Israel for a kite as balloon aerial vehicles not Tripulados system was designed to keep track of Hezbollah in the Lebanon and Hamas in the West Back in the event that occurs thought that they could do another barrage of rockets. Looking design, reminded me a few questions asked once another interesting system by another inventor, he was going to use your system to create energy while flying a kite, although a very sophisticated Comet even more than the Afghanistan - in fact you could even be another good use for this kite flyers?

I have therefore asked; "I see is a good start with some problems of stability, but those are soluble, and modifications have been set forth to allow the turbine so that points toward the wind, while the profile wing or comet maintains its high angle of attack"?

Indeed also wanted in each of these cases, although has considered the possibility of putting strakes on the top of the wing Airfoil yaw, creating avant-garde which allow excess relative to by-pass when one wing guiña too far - perhaps in a slider - purely mechanical wind slot-based morphing or configuration dual lines with a lower among them to stabilize or also introduce winglets wing wing?

In thinking about what occurred to me that perhaps a "Gull wing" configuration with the slider border between wings as well as a wing tracks decreases it the elevator on the other hand pulling a spoiler of some kind. And in both cases I was wondering; for now, are their main concerns with stability? Or are there other issues also refers with too much?

You see, I guess that when it's that old saying; Go Fly A Kite, that some friends quite literally means are serious about what could actually make a comet that well-designed and all applications might be able of. Both of these designs appear to be negotiable, no problem, once it is reliable, people want them. Thus, if you tell me "go fly a kite" - I'm all in! But won't believe what will make my kite. Please consider this.
