In all honestly, unless you get down to the very untricky SULs (ProDancer SUL), most sport kites will require smooth winds, foot motion, noticeable arm waving and 50# lines to fly below 3 mph.
3 mph is about 4.5 ft/ sec, a moderately quick walk is about 3 mph. Next time you are walking near that speed, see how much apparent wind you feel on your face. It is not much.
Remember tricks are about knocking the pressure off the sail, which is the very opposite of what an SUL needs to do to fly in such low winds.
People who have kites which fly from the wind of a bird sneeze at 2 blocks away are probably pretty good fliers or perhaps prone to stretching the truth a bit.
I'll definitely take your advice there John - I did kinda think the difference between a SUL and a UL would be degrees...
It's good to hear realistic opinions on what's actually achieveable
I think I'm really just after a kite that flies just lower than my Talon UL
Today I was trying to fly it in about 3-5km of wind and had to REALLY work it to axel and 540
I'm told that the Talon UL isn't a true UL - more of a light STD - and even the Deep Space UL flies lower - so yeah, it gets a little confusing to an intermediate pilot like myself
That's nonsense, the talon is a true ul it's just that the ds ul is it's most natural comparison and that flies nearly like an sul.
You need to decide whether you want a true no wind kite or something that is a touch more weighty that has a higher aspect ratio and more trickable. You also can't break the laws of physics and you will need to move a bit.
