This is video from me L2 cert flight on 9/8/18 through Tripoli, slowed down t' 30% o' t' original video speed. Ya scallywag! I flew a Cesaroni K820 in a HyperLOC 835 kit I built earlier this year. T' rocket passed mach 1 on its way up t' a 9100ft apogee before comin' back down about 3/10 o' a mile away from t' launch site.
