I remember when we had the 1st gen of the BOOST stock software...I blew up (4) 13.5 motors within 3 hours (until I ran out of 13.5 motors, then I go to the 17.5...3 more blew up within another 2 hours)...1 motor per round, less then 3 minutes each. How many motors you can provide and how many DNF you can afford?
