Description

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!  Stnading 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 ft!  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:

Motor Predicted Altitude
Estes 16-4 710 ft
Aerotech E20-4 815 ft
Aerotech E30T-4 930 ft
Aerotech E15W-4 930 ft

Estes F15-6 1113 ft
Aerotech F23FJ-7 1267 ft
Aerotech F20W-7 1478 ft
