The Super Big Bertha is the upscale version of the 3-model classic line: the Baby Bertha, the original Big Bertha, and now the Super big Bertha! Standing 36.8 inches tall, with a monstrous 2.6 inch (BT-80) diameter, it draws on 29mm motors to power this mid power model up to 1475 feet! While instructions may indicate that white glue is sufficient for this build, it's best to use mid-power building techniques, It's best to use epoxy instead of white glue or CA glue, and use rail buttons instead of launch lugs to ensure straight and stable flight. A number of Aerotech single use motors fly well in this rocket, in addition to the recommended Estes motors:MotorPredicted AltitudeEstes 16-4710 ftAerotech E20-4815 ftAerotech E30T-4930 ftAerotech E15W-4930 ftAerotech E30T-7980 ftEstes F15-61113 ftAerotech F23FJ-71267 ftAerotech F20W-71478 ft
