The Baby Bertha rocket is a half-sized version of one of Estes' most popular rockets: the Big Bertha. The Baby Bertha stands just 13 inches, making it an ideal intermediate building experience. This model rocket is both high-performance and easy to build.
Assemble and finish the Estes Baby Bertha within just an hour of building. You can paint it like the package or create your own Go Wild design! The kit features laser-cut wood fins, a blow-molded nose cone, and easy-to-apply self-stick decals.
When you power it with Estes standard model rocket engines, it streaks to 575 feet. It can be easily recovered due to its included colorful 12-inch parachute.

Customer Reviews
I bought this along with three other rockets. This one arrived with the balsa sheet containing the fins split in two with two of the fins broken. They were easily repaired by gluing them back together but shouldn’t have been broken in the first place. Aside from that, the model was easy to assemble and looks good.
I built a Big Bertha and a Baby Bertha with the intention of using the Big Bertha for the gender reveal. However, at the last minute, there was a change in plans for the launch area. I quickly set up the Baby Bertha and used it for the reveal. This rocket's large diameter body tube carried streamers and red chalk powder to an altitude of 250 feet with no problem on a B engine. I wasn't going for altitude, but I needed to keep from crop-dusting the crowd. The launch was an absolute success!
I am happy with my purchase. Well packaged and everything is in tacked. We haven't built it yet. Waiting for the grandson this Thanksgiving to help build them launch.
