Customer Reviews

The Estes Major Bertha rocket is a single of the most hassle-free, but satisfying rockets to develop and fly.
Initial, the design is straightforward - quick to construct, even for the beginner.
Second, the rocket is impressively major. Kids like to launch big rockets, and the Major Bertha fills the bill. Given that of its substantial size, the Major Bertha has a slower take-off, one you can actually see, instead of the "zip and gone" take-offs of the smaller rockets. Also, considering that of its size, this is a rocket you will not most likely shed. It will not go so high, even with a C6-5 engine, that you will lose 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 happen with the Huge Bertha. It is a fantastic 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 more than and more than with consistent efficiency.
Lastly, it has a substantial parachute which is painless to spot in the sky and floats the rocket to earth safely.
I hugely recommened the Big Bertha rocket to all beginner rocketeers. It will offer hours of fun and it a outstanding way to study the fundamentals about model rocketry.

Estes Big 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 continually that way.
Initially off, Estes has re-designed propulsion to single engine simplicity.
For a large number of years, Big Bertha was cluster-powered it sported 3-engine
power. It required a "whip", a network of various engine clips for ignition - when things went correct.
Cluster power supplied a significant benefit three C.8 engines legitimately yielded even 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 3 C.8's cost less than a dollar. Those were the decent old days.
If you had been a power-freak, clustered C.8's had been the only way to go. Large Bertha nevertheless, almost in no way co-operated. Very 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 had been distinctive back then, plain nichrome and not the squib.
Lift-off frequently involved only a single or if you were lucky, twin-engine power. Large Bertha would veer wildly off the pad. The older version of BB freqently had a payload compartment. Heaven assist you if there were live animals on board. Massive Bertha also exhibited a different benefit - it could bounce back from prangs with minimal damage.
Nonetheless, there had been uncommon occasions when every thing went ideal, and BB was a thing of beauty. It was worth the trouble.
I appreciate this chance to walk down memory lane. Huge Bertha is nevertheless basic to construct, and is readily customizable at smaller extra expense, to two-stage configuration, payload compartments, even single-engine D or E power, whatever. Maintain the fin size as specified, even though. It is primed for terrific enjoyable and the basis of new memories, but new rocketeers have no notion what they've missed.
