After several attempts in t' past two weeks I was finally able t' launch a finless rocket clearly over 500 meters usin' launch and recovery GPS coordinates (740 meters). Blimey! T' rocket was powered by 65% KNO3 and 35% sugar (sobitol), t' same fomulation used in t' Sugar Shot t' Space project. T' propellant was case bonded t' t' EMT steel motor casing, nose cone was turned from wood. I wish t' thank Google Lunar X-Prize Team Selene for sponsorin' this competition.
