You may have seen stunters flying one above the other, from two up to as many as 10 or more. This is called stacking and results in exceptionally high tensions which can create opportunities such as jumping and skiing. Bear in mind that this has the potential to be very dangerous and unless you are keen to see the inner workings of a hospital, we suggest you venture into this side of the sport with caution.
Stacking lines for deltas consists of FIVE lines with overhand knotted loops at each end, each between 60-90 cm (24-35 in). All stacking lines MUST be exactly the same length, 80 cm (31 in) is usually the standard length. The 5 lines connect onto all the bridle connection points and then on to the corresponding points on the following kite and so on. If you find the kites jostle when in flight, shorten the length of all the stacking lines. As the number of kites stacked increases, so will the pull and you will have to change your flying lines to be able to cope with the increase in tension.
This is a very simple process if you follow the steps below and consists of attaching 5 lines to each of the bridle connection points on the lead kite to the corresponding positions on the following kite.
Set up the kites in the order you want them to fly. This system is suitable for stacks of up to four kites depending on the size of kite.
Starting with the lead kite feed the stacking line through the wing slot and over the fitting. Do this for all four leading edge connectors.
The following kite is connected the same way.
The spine line is now connected and adjusted to fit. The slipknot is then locked in place.
Hold the kites by the bridle loops of the lead kite and make sure all lines are equally tensioned. Adjust if necessary. The stack is now ready to fly. Remember that kite stacks can produce a lot of power so be careful!
