Buyer Reviews

The Estes Major Bertha rocket is one of the most rather simple, however satisfying rockets to build and fly.
First, the style is uncomplicated - very easy to construct, even for the newbie.
Second, the rocket is impressively big. Kids like to launch big rockets, and the Big Bertha fills the bill. Mainly because of its massive size, the Large Bertha has a slower take-off, one particular you can basically see, rather of the "zip and gone" take-offs of the smaller sized rockets. Also, given that of its size, this is a rocket you will not most likely shed. It won't go so high, even with a C6-5 engine, that you will shed sight of it. I have flown some rockets that went so high I lost sight of them and lost them to the wind drift. This will not take place with the Significant Bertha. It is a awesome rocket to launch in a somewhat confined lauch field, as it will not drift that far downfield.
Third, this is a basic rocket to operate, and it is durable and reliable. You can launch it over and more than with consistent overall performance.
Finally, it has a large parachute which is quick to spot in the sky and floats the rocket to earth safely.
I extremely recommened the Major Bertha rocket to all newbie rocketeers. It will provide hours of enjoyable and it a excellent way to find out the fundamentals about model rocketry.

Estes Large Bertha traces its lineage to 1963, and it has evolved more than the years to a non-frustrating afternoon fun in rocketry. It wasn't often that way.
Very first off, Estes has re-developed propulsion to single engine simplicity.
For quite a few years, Large Bertha was cluster-powered it sported 3-engine
power. It needed a "whip", a network of several engine clips for ignition - when issues went perfect.
Cluster power provided a tremendous advantage 3 C.8 engines legitimately yielded extra than 20 nt-sec of impulse. Even the D-series, when it was introduced, was rated at 13.5 nt-sec. A cluster of 3 C.8's price less than a dollar. Those had been the very good old days.
If you were a power-freak, clustered C.8's were the only way to go. Massive Bertha but, pretty much never ever 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 several back then, plain nichrome and not the squib.
Lift-off regularly involved only a single or if you were lucky, twin-engine power. Significant Bertha would veer wildly off the pad. The older version of BB freqently had a payload compartment. Heaven aid you if there had been reside animals on board. Significant Bertha also exhibited one other advantage - it could bounce back from prangs with minimal damage.
Even so, there had been uncommon occasions when every little thing went perfect, and BB was a point of beauty. It was worth the trouble.
I appreciate this opportunity to walk down memory lane. Significant Bertha is nevertheless hassle-free to build, and is readily customizable at little additional expense, to two-stage configuration, payload compartments, even single-engine D or E power, whatever. Retain the fin size as specified, though. It is primed for terrific entertaining and the basis of new memories, but new rocketeers have no idea what they've missed.
