Fantastic Jul 08, 2010
Easily the best flying rocket of my fleet. It goes straight up levels off into a graceful arch. Just as it starts to fall the parachute deploys. Beautiful every time. Also it is very durable. The first launch i stuffed too much wadding and the cap failed to come off. It crashed right into the ground at great speed and with a good thump, but suffered no damage. A great Rocket and a great buy.

 Didn't know I needed other items for it to operate Dec 29, 2009
Dang - I bought several of these only to find out I need about $50 - $100 additional items in order to make it work. Money down the drain.

 A classic rocket that withstands the test of time. Mar 29, 2009
You can't go wrong with an Estes rocket kit. The Big Bertha is one of the longstanding entires from their lineup. The only differences between this Big Bertha kit and those that I built in the 70s are the decal package and the fact that the fins are now laser cut. Other than that it's precisely the same.
* A joy to build
* A riot to fly
* Dynamite learning experience -- building and launching the rocket
* Good quality materials

Big Bertha has come a long way May 11, 2008
Estes Big Bertha traces its lineage to 1963, and it has evolved over the years to a non-frustrating afternoon fun in rocketry. It wasn't always that way.
First off, Estes has re-designed propulsion to single engine simplicity.
For many years, Big Bertha was cluster-powered; it sported three-engine
power. It required a "whip", a network of multiple engine clips for ignition - when things went right.
Cluster power offered a huge advantage; three C.8 engines legitimately yielded more than 20 nt-sec of impulse. Even the D-series, when it was introduced, was rated at 13.5 nt-sec. A cluster of three C.8's cost less than a dollar. Those were the good old days.
If you were a power-freak, clustered C.8's were the only way to go. Big Bertha however, almost never co-operated. First, there is the inherent 15% variation from engine to engine, which affected thrust, duration, and delay train. Then, that whip colluded to stimy simultaneous engine ignition. Even the ignitors were different back then, plain nichrome and not the squib.
Lift-off frequently involved only a single or if you were lucky, twin-engine power. Big Bertha would veer wildly off the pad. The older version of BB freqently had a payload compartment. Heaven help you if there were live animals on board. Big Bertha also exhibited another advantage - it could bounce back from prangs with minimal damage.
However, there were rare occasions when everything went right, and BB was a thing of beauty. It was worth the trouble.
I appreciate this opportunity to walk down memory lane. Big Bertha is still simple to build, and is readily customizable at small additional expense, to two-stage configuration, payload compartments, even single-engine D or E power, whatever. Maintain the fin size as specified, though. It is primed for terrific fun and the basis of new memories, but new rocketeers have no idea what they've missed.
VERY BIG, VERY Fun Mar 05, 2008
This rocket is a classic and flies very well. I also like the size of this rocket. Unfortunatley, I lost this one upon my first launch to a tree. I do plan to get another one, so that should say something. The only negative I would say it that is the rocket did not launch "slow" like a real rocket. It launch just as any otehrrocket does, but its still fun.
