Sirius Rocketry - For the Serious Rocketeer!

Estes Big Bertha


  • Model: EST-1948
  • Manufactured by: Estes

There is the Estes Alpha, and there is the Big Bertha.  Both competing for the quintessential definitive Estes Rocket.  Big, burly, realistically slow liftoffs are all reasons that the Big Bertha is one of the oldest and best-selling Estes kits. 

Big Bertha is an Estes original! Big, burly, black and beautiful perfectly describes this classic. She's an all around Estes favorite that has truly withstood the test of time. Over the decades, Big Bertha has been most modelers' first big build. While standing on its massive fins, this big black rocket checks in at an impressive 2 feet tall. If you've never flown a Bertha, get one and launch it. Once you've flown it, you'll take it to every launch!

The Big Bertha gives you a slow, realistic liftoff. What a thrill it is to watch! Propelled by powerful standard Estes engines, this beauty travels to 500 feet and comes back to earth with a decorated 18 inch parachute. Quality Estes body tubes, laser cut balsa fins, molded plastic nose cone and easy to apply self-stick decals make for an afternoon of building enjoyment. In one afternoon your Bertha is ready for an exciting time at the launch field!
