Big Bertha Model Rocket Kit

Over the years, Big Bertha has remained an iconic choice for many model rocket enthusiasts. Its slow, lifelike take-offs are a defining feature of this enduring classic.

Big Bertha, an original creation by Estes, can be aptly described as large, robust, black, and stunning. It has solidified its status as a beloved choice among Estes enthusiasts, standing the test of time. Throughout the decades, Big Bertha has been the go-to choice for most modelers looking to tackle a larger-scale project. When perched on its substantial fins, this impressive black rocket reaches a towering height of 2 feet. If you haven't experienced a Bertha launch before, it's time to get one and send it soaring skyward. After your inaugural flight, you'll want to take it along to every rocket launch event!

The Big Bertha promises an exhilarating, leisurely liftoff, a spectacle to behold. Powered by reliable standard Estes engines, this beauty reaches heights of up to 500 feet before gracefully descending back to Earth with the help of an 18-inch parachute. Constructed with top-quality Estes body tubes, precision laser-cut wood fins, a molded plastic nose cone, and easy-to-apply self-adhesive decals, assembling your Bertha becomes a satisfying afternoon project. In just one afternoon, your Bertha will be ready for an exciting adventure at the launch site!

"The best vehicle for key-chain camera rocket videos!"
rbeard2 (Dayton, OH)
All that has been said about the Big Bertha in the other reviews is true - it is a classic, slow take-off, rugged beast that is fun to build and flies great. Easily modified to a 24mm motor mount (just purchase a motor mount tube and extra sheet of 3/32 balsa for reinforced centering rings). Also, if you have discovered the super cheap key-chain style HD cameras for sale online, this is the perfect rocket to strap them onto! Just attach your fully charged micro camera to the top of the body tube just under the nosecone shoulder with 5 or six tight wraps of electrical tape (doesn't pull off the finish like masking tape). The Big Bertha shrugs of any aerodynamic disturbances due to her overlarge fins and the extra weight of the camera appears not affect flight at all!

"Everyone should have one"
gfbullock
This is a great flying rocket and should be in every Fleet. A staple to most Flyers. It is easy to build(good first rocket)and looks great. But I enjoy flying as much as any other low power rocket I have. Also, if you go through old Estes catalogs you can find many different paint schemes that look great.

 
"Big Bertha modified plus 7"
uvawgrad
I had this rocket as a 12 year-old that I built with my Father, and now as a 43 year-old with a 4 year-old Son this was our first. (Okay, I know I'm rushing it) My Son is a big fan of Thomas the Tank Engine, and he wanted a Hiro rocket. I couldn't find any train decals I was happy with, so I just put big letters HIRO vertically on both sides and used some of the original decals. The body tube was crushed a little on one end during shipping, so I cut a few inches off and added an extension which added 7 to the total length. I had someone run a simulation on RockSim and they told me that adding weight to the forward end of the rocket just added more stability, and that definitely turned out to be true. I had toyed with the idea of having a rocket with a huge chute for it to come down as slow as possible because I find the slower the fall the more interesting it is. I used a thin black trash bag, and cut out a chute approximately 27. One plus to the thinner chute material is it's very soft & pliable compared to factory chutes and fills with air very quickly. With a little baby powder there is no way this chute will stick together and not deploy. To me, it is more fun watching the drop than the launch. Definitely not one to launch with any breeze or any trees or obstacles nearby at all. She definitely returns to terra firma S-L-O-W-L-Y And on a C motor it seems to go as high as one without any length addition, and seems to track truer than one with the original length. I like larger rockets, and this one has the maximum diameter you can get from Estes (1.64) without going above a C motor. I highly recommend this as a first rocket due to the ease of build and slow, majestic lift-off.

 
"Excellent first rocket"
Tarasdad (Lancaster)
I received the Estes Big Bertha kit as a gift, my very first model rocket build. This is a very easy kit to assemble, with clear, easy to follow instructions. Parts are high quality which helps significantly with the build. I used Titebond II exclusively throughout the build with great results. The only area where I recommend extra care be taken is in sanding the fin edges. To ensure a good glue joint the root edges must have the burn (brown color) from the laser removed to expose clean balsa. Care is required to keep the edges square and flat. Using the recommended method of stacking the fins works well, although care must be taken to keep them properly aligned. Once the burn residue is gone and the leading and trailing edges have been rounded use the double glue technique in the instructions to glue the fins on. Done right you'll end up with a joint that is stronger than the materials being glued together! I chose not to use the kit paint scheme and supplied decals in order to make my Bertha unique. Red and white were used to create an old school look. Decals were a mix of US flags from a sheet of RC airplane decals and text decals created on my P-Touch printer. This rocket just asks to be customized, or you can peruse old Estes catalogs and reproduce one of the many wonderful paint schemes it has carried throughout its long life. To date I haven't been able to launch my Big Bertha (real life getting in the way, as happens) but hope to do so soon. I can heartily recommend this kit as your first model rocket build, and guarantee that once you've built one many more will follow. I already have plans for my second! And third, maybe fourth....
