Rokkaku bridle and bow adjustments

Here are two videos showing the tuning adjustments used on a rokkaku kite.

If either of these adjustments are a long way off the kite will either pull like a donkey and not fly high, or swing around wildly from side to side, or fly forward then drop back repeatedly.

But within a small range of adjustment you can choose how high it flies or how hard it pulls.

Angle of attack or bridle height adjustment.
