Hi. The real balistic pattern was back in the late 1980's. For Masters their was a list of 45 maneuvers you would pick with different K-factors. You could pick your best 12 maneuvers and try to get the maximum K-factor. I was fortunate enough to win the 1987 Nationals the last time non-turnaround pattern was held at the Nats. That sure was fun back then but now the air space it would take to do that type of flying isn't available any more. You could do slow, 4 and 8 point rolls from horizon to horizon with no box to worry about. Jim
