Analysis

During a pleasure flt in an experimental acft, during the takeoff roll, the eng sputtered, however, the plt continued the flt. After takeoff at aprx 30 ft the eng sputtered again. The plt made a sharp 45 deg turn which put him on downwind, however, the acft was kept in a nose high attitude. At aprx 300 ft the eng sputtered again then quit. The left wing dropped and the acft completed one turn and impacted the terrain in a 70 deg nose down attitude. There were no mechanical failures or malfunctions reported.
