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