Big Bertha Model Rocket Kit (EST1948)

Big Bertha Model Rocket Kit is an Estes original and a time-tested favorite, perfect for beginners and seasoned hobbyists alike. It’s a big, approachable build that delivers a slow, realistic liftoff and a memorable flight that stands out at the field.

The kit includes quality Estes components—sturdy body tubes, laser-cut wood fins, a molded plastic nose cone, and easy-to-apply waterslide decals—paired with standard Estes engines for reliable performance. When launched, it reaches about 500 feet and returns with an 18-inch parachute, providing a rewarding, confidence-building experience for an afternoon of hands-on modeling.
