Having the lines pre-marked serves 3 purposes. (1) You can use the marks to keep the right and left sides the same length. (2) There are red and green marks on the main bridle as well. TOTL provides suggestions (when you buy a 'real' NSR) about different main bridle vs outhaul combinations. For example, main bridle outhaul effect ----------- ------- ------- red red quick turning, pulls hard... red green good turning, light pull... green red ...etc... green green ...etc... I don't remember the combinations right now (i.e. The above effects are not real!). (3) Since every TOTL NSR is setup with the same colored marks, NSR flyers can compare settings with one another. We found this to be VERY helpfull in trying to find that *perfect* setting for the wind conditions of the moment. Hope this helps...

When you are familiar with the kite, you know that on red mark it turns such and such, on green tighter, on black even more oversteer - or vice versa.

Darrin, are the production NSRs really so identical that setting bridle on same color marks will make them fly similarly?

The outhaul of the NSR is actually composed of two pieces of string. One is a loop tied off with an overhand knot which is larksheaded onto the leading edge. The other piece is a length of line with an overhand loop at one end and the markings at the other, loose end. The loose end is attached via a sort of hitch (the I remember it is that you put the loose end through the second piece's loop, wrap it around back, and then pull it back through the loop). The 4 markings (black, green, green, red) are the suggested outhaul settings and allow you to switch between a dihedral and an anhedral. The kite is delivered with the bridle set between the red and black marks on the main bridle, and on the black mark on the outhaul. I don't know if many people maintain this bridle setting...

YES. Identical... NO. Keep in mind that our (Air Art's) major concern was flight speed and speed changes in gusty wind. We found that the same setting usually made the the kites fly at the same speeds. Some of the handling was a wee-bit different, but not enough to worry about. There were some radically different settings that would have the kites flying at the same speed at 8mph and totally different speeds at 8.5mph. You could spend a lifetime playing with main bridle and outhaul combinations. There is always a better setting for *todays* wind that just won't work for *tomorrows* wind. The NSR has a fairly deep sail. There could be *measurable* differences in the sail area from one kite to the next without it having any appreciable effect on the kite. And then there was that one kite... It was EXACTLY the same size, shape, etc as all the others and it just didn't want to fly. All of the kites made by TOTL share the deep sail idea. This permits greater variation in sewing and assemble while still having a flyable\sellable kite as compared to kites with a flatter sail.
