Estes Big Bertha


Big Bertha is an Estes original! She’s an all-around Estes favorite that has truly withstood the test of time. Over the decades, Big Bertha has been most modellers’ first big build. 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 lift-off. 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 an 18 inch parachute. Quality Estes body tubes, laser cut wood fins, moulded plastic nose cone and easy to apply water-slide decals makes this rocket kit a perfect companion for an afternoon of building enjoyment.

Note: Rocket engines/motors are available for purchase however, they can only be collected from our store in Frodsham, Cheshire.
