The STACK figures are the basis of competition flying, but some of them are hard to make out from the static diagrams. In order to make them clearer, I have produced a set of animations of all of the figures. The animations now allow you turn both the grid and figure lines on and off. This can give flyers an idea of how the figures look when seen against a clear sky (how the judges will view them).
The animations are produced in Flash. In order to view them you will need to have (at least) the Flash 4 plug-in. You will still be able to view the animations with version 3, but the new buttons won't work.
The figures are flown against an imaginary grid in the sky which fills an area 53° to either side of the flyer and 53° up. This grid is calibrated in percentages, which can be read as feet if you are flying on 125ft lines - see explanatory diagrams of the Wind Window and Grid. The figures can be reversed left to right.
NOTE 1: These figures have now been superceded by the new IRBC figures. They have now been animated and you can see them here. The figures on this page marked NEW were never official STACK figures, but were being considered for acceptance in April 2004. Any decision on these was pre-empted by the adoption of the new IRBC figures.
NOTE 2: These figures are Flash only. They will never be updated to SVG/HTML5 and are only left here for the sake of history.
