Intermediate Skill
(Formerly Skill Level 1)

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. John A.

    Fantastic rocket. Built it as a kid and just build another one 30 yrs later. Estes, don’t ever let there be a time that Big Bertha is absent from your lineup.

    One small change request. Incorporate a baffle system so we don’t need to use wadding. I’ve flown this model so many times I bet I’ve put 10 packs of wadding in it over the years. I’ve added on to my new build and love it even more.

      Thank you John, as Vern Estes’ favorite rocket, we don’t see it going anywhere! Also if you love the Big Bertha, be sure to check out the brand new Boosted Bertha, with the same Bertha feel in a multi-stage package.

  2. Scott

    One of the best all time!

    One of the best rockets of all time in the Estes rocket collection! A must have for any rocketeer.

    Bertha Baby!

    I got back into model rocketry to keep my grandkids entertained and have to admit, I’m hooked again, I built a Big Bertha recently and launched on a C6-5 with a keychain HD camera (which we didn’t have back in the day) and got some awesome video…try it! Since I built Big Berta I’ve just finished the Mercury Redstone and have a V2 on order. We are lucky to have a big field at a local county park very close, so we are launching rockets on a regular basis…it’s fun!

    One Of A Kind

    I had Big Bertha and I really liked it. Most rockets launch fast but I liked how Big Bertha had a really realistic launch

  5. Andrew

    Classic rocket

    I used to fly this rocket when i was a kid, just got one for my kids. Very easy build and great in the sky. Very durable rocket

  6. Andrew

    Awesome

    flies straight. loves the C6-5. Big tube is easy to pack. love the huge chute it comes with, but I might refrain from using that on a windy day… Good predictable flights. pretty easy build and I love the look of it. If I ever lost this one I would get another to replace it. one of my favorites and a classic for a reason (its great)

  7. Dean

    A true classic.

    I built and flew a Bertha kit when I was a kid some 40 years ago. This is a time-proven classic that still generates excitement when brought to the launch pad. I modified my current Bertha to include an E-sized motor mount and ejection baffle. It’s a great flier on D12-5s, but I’ve never gotten up the nerve to try the E. The C11 option gives a little more kick off the pad, too. Everybody should have a Big Bertha in their fleet.
