I will mention again that you should check the rules for the event that you want to enter it in. Balloon bust is mentioned in the AMA rules but I don't know of any one club that holds the event that way. Some clubs figure speed into the event. As mentioned, we used to time 6 or 7 laps from take off, then turn the pilot loose to bust balloons. Speed was factored into your score. For our Jason Pearson Memorial Turkey Shoot, we have been using the old W.A.M. rig and their rules. Just take off, 6 minute time limit for how many you can bust. Jason's Dad donated the original W.A.M. equipment and we use that.
Too cold out for balloons any more this year!
Type at you later,
