Matt Johnson's Cosmostrator, me bucko, modified for one launch rod. Avast, me proud beauty! Matt previously tried a three launch rod construction, but it be too difficult t' align t' rod, so Joe Mosher o' SMASH suggested he modify t' rocket for one launch rod, me bucko, right though t' center. T' nose cone was hinged t' flip back into place after t' rocket left t' rod, but t' whole rocket flipped!
