A 250mm difference means that the bridle element is entirely wrong. If you have flown kites you will know that 25mm of pull on the flying lines will cause sufficient asymmetry to make the kite turn. 1 element of a bridle effectively missing may well make this size of kite unflyable imho!
I attach the manufacturer's specs for the bridles' lengths. The hand-written lengths besides each bridle are the actual measured lengths .
I am pretty sure that b2 on the red side ( 1210 mm) is 250 mm shorter than the specs length of 1525 mm). Even on the blue side, b2 is still shorter, but only by. 65 mm
For the other bridles,too, differences in length do exist, both as compared to the specs and also between right and left sides. Depending on the bridles, these differences range between 20-60 mm. Aside from the b2, shouldn't 10-60 mm difference affect the kite?
Does the length of the bridles determine the angle of attack of the kite? I have a hunch it does, but I don't quite understand how. May be, if my measurements are correct, the angle of attack may be completely off, on account of this: either too steep ( stall) or too small, or( even negative ! Add to this the length differences between the two sides!
Any comments ?
