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 modelers’ 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 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 an 18 inch parachute. Quality Estes body tubes, laser cut wood fins, molded plastic nose cone and easy to apply waterslide decals makes this rocket kit a perfect companion for an afternoon of building enjoyment.

  1. William

    Iconic rocket kit

    Almost every rocketeer I know has a BB in their fleet. I’ve had quite a few, and a few of the variants. This is a low and slow, straight-flying gem.

  2. Mikey Taco


    I don’t like the new paint scheme, I like the one from the 80’s, but whatever it looks like doesn’t matter the great thing about it is it flies great.

  3. samman


    This thing is amazing!. I launched mine three times and it worked perfectly. It was my first rocket so I had a little trouble but nothing huge.

  4. Been there done that

    Best rocket ever owned

    This thing is a classic! It is great for the first time builder and pros alike. It may not be the highest flying by building it from scratch gives you the best sense of accomplishment ever! Everyone should own one of these classics!

    good for anything

    my teacher retired this year, and i wanted to give him something special. i got a Big Bertha and had the whole class sign the body tube. it is good for mildly windy days.

  6. Mike

    Good first rocket

    This was my first rocket over 30 years ago. I performed flawlessly until of course it got stuck in a rather large tree.

  7. Joeschmo


    In my opinion the Big Bertha is a great, fun rocket to have, it is fun to watch when launching, and lands smoothly. Building it is also a pleasure, and a challenge. This is another one of Estes great products! Very pleased.

  8. Hackwood

    Very nice

    I “happened” upon an older “Super Big Bertha” and this thing is fun. Not the fastest or highest flier, but straight and true and very easy to track. Everybody should get one of these. 🙂 🙂 🙂 🙂

  9. doug

    tons of fun

    slow takeoff straight flying and easy to follow. recovery is easy to track just don’t aim into the wind, it’ll weather vain on it’s own. oh i forgot the best part, you get to build it yourself.

  10. joey


    this roket may not be “snap together”but this rocket is one of estes’s BEST rockets
