Three years after startin' this project and I finally got t' maiden flights in. First flight was on 3 D12-5's and was expected t' be about 564' accordin' t' t' simulator tests I ran. Well, blow me down! When t' launch button was pressed all 3 motors roared t' life and she left t' pad on a column o' smoke. Avast! I estimate it reached about 550' more or less.  Parachute deployed at apogee and rocket started a long descent driftin' with t' wind and landed halfway down range. Begad! Recovery was made after range opened and rocket be recovered with a small din' t' one fin tip. Blimey! No other damage was noted and rocket be taken back t' table and prepped for next flight.
