I successfully did me HPR L1 certification attempt on September 17, matey, 2016, arrr, in Berwick, Maine, with an Estes Leviathan. Aye aye! T' motor was a Cesaroni H133 with a 9-second delay. Begad! Apart from a little mud on one fin, thar was no damage. Ya scallywag! T' rocket was recovered lookin' straight out o' me workshop.
