This be t' team's third P motor test, shiver me timbers, and our most successful one t' date. Avast! Usin' only 3 grains, t' motor's volume loadin' increased. T' new propellant formula burned slower, me hearties, and with better specific impulse. All combined, our various improvements yielded 15% higher performance than last year. Blimey! We are preparin' t' fly this motor in March. Ahoy! https://wikis.mit.edu/confluence/display/RocketTeam/P9100
