The Gomberg Fled is a cross between a Sled kite and a Flare kite. This is a framed, light wind kite designed for 4 - 11 knots. It will happily lift my gopro in quite light conditions where my foils would not fly. It's quite stable and flies at quite a steep angle - I have occasionally seen it fly directly above my head. The Fled has an adjustable line on the back of the kite for adjusting the bow of the kite. I haven't experimented too much with this - I put a slight bow in it and it flies nicely - I haven't measured the distance between the line and the back of the kite. I assume adding some bow into the kite is something like dihedral on a glider's wings which adds stability. Seems to work pretty well - you can see it clearly in the two photos below.
The kites are made in China and the workmanship is adequate. Certainly not confidence inspiring. It just all seems a little light to me - particularly the horizontal spar pockets which are velcro pockets. The Fled comes with a drogue attached which seems to work quite well. There is certainly plenty of pull in light winds and if you wanted the kite to sit at a lower angle, you could always try a long fuzzy tail.
The vertical spars are sewn into their own pockets and stay in the kite, you only need to assemble the two piece horizontal spar for it to fly. The only downside to this is when it's in it's bag, the bag is 5ft tall. I don't ever remember this kite waving wildly side to side or looping or showing signs of any bad behavior at all - it's quite well behaved. Which is just as well as I wouldn't want to see this hit the ground with any force being fairly light weight. I have mine on 150 pound line and it pulls this with no problems at all. Pulls the gopro up with ease too. It would handle a small compact camera but a SLR might be a bit of a stretch.
Overall, I think this is an excellent light wind KAP or line laundry rig. A nice, taught flier that doesn't flap or misbehave.
