Big Bertha Model Rocket Kit

Over the decades this is the first big rocket for many modelers! Slow, realistic lift-offs from this true classic!

Big Bertha is an Estes original! Big, burly, black and beautiful perfectly describes this classic. 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. While standing on its massive fins, this big black rocket checks in at an impressive 2 feet tall. 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 a decorated 18 inch parachute. Quality Estes body tubes, laser cut wood fins, molded plastic nose cone and easy to apply self-stick decals make for an afternoon of building enjoyment. In one afternoon your Bertha is ready for an exciting time at the launch field!

"Good Rocket, Good Price"
bsgauthier
Hobbylinc has great prices on Estes model rocket kits. Big Bertha is a fine Estes model kit with clear instructions, though I'm not fond of the rubber band shock cord or the way Estes mounts it. I like to see the shock cord attached to the motor mount with Kevlar string. Previous comments referred to the double glue bond fin attachment technique. I use the technique but take it one step further by using my hobby knife to drill small holes along the fun guide lines. This makes tiny glue rivets when the glue dries, giving a little more strength to the fin attachment.

"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!

 
"Very good first step up model!"
dewaldron1 (110A S Gallivan Ave, East Camden AR 7170)
Since I was 14 years old I have probably built 3, no 4 Big Berthas. Now I'm 63, so that tells you how long Big Bertha has been around. The reason why is it is just a very solid model rocket. It's an easy build, easy to paint and a great flyer. I have even flown mine on Quest D16 engines! Try it as a step up from your first beginner model. You won't be disappointed.

 
"An Absolute Favorite to Build and Fly!"
miataman1
I have an entire fleet of Estes rockets, and this is easily one of my favorites. It is an easy build for beginners, yet even seasoned rocketeers count it among their must haves. It is always taken along on launch day due to its reliability and beautiful, comparatively slow lift-off. There are really no negatives that come to mind. It has a good price point and is a proven winner. That's probably why Estes has offered this rocket for so long. One tip that Estes seldom mentions is a tip to avoid excessive drift when launching with a C6-5: You can cut a hole in the parachute center about 3 inches in diameter. The rocket will still have a gentle landing but will not drift too far if there is a breeze. I have done this with Big Bertha and many other rockets with no mishaps due to cutting the parachute center hole.
