Client Evaluations

The Estes Major Bertha rocket is one of the most effortless, however satisfying rockets to create and fly.
1st, the design is uncomplicated - uncomplicated to construct, even for the novice.
Second, the rocket is impressively huge. Youngsters like to launch massive rockets, and the Massive Bertha fills the bill. Simply because of its huge size, the Significant Bertha has a slower take-off, one you can basically see, as an alternative of the "zip and gone" take-offs of the smaller rockets. Also, because of its size, this is a rocket you will not likely shed. It will not go so high, even with a C6-five 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 happen with the Massive Bertha. It is a terrific rocket to launch in a somewhat confined lauch field, as it will not drift that far downfield.
Third, this is a straight forward rocket to operate, and it is durable and dependable. You can launch it more than and more than with constant performance.
Finally, it has a large parachute which is effortless to spot in the sky and floats the rocket to earth safely.
I very recommened the Significant Bertha rocket to all beginner rocketeers. It will give hours of entertaining and it a wonderful way to study the fundamentals about model rocketry.

Estes Massive 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.
Initially off, Estes has re-designed propulsion to single engine simplicity.
For a number of years, Significant Bertha was cluster-powered it sported 3-engine
power. It necessary a "whip", a network of many engine clips for ignition - when factors went correct.
Cluster power supplied a large benefit 3 C.eight engines legitimately yielded far more than 20 nt-sec of impulse. Even the D-series, when it was introduced, was rated at 13.five nt-sec. A cluster of three C.8's price less than a dollar. Those had been the excellent old days.
If you had been a power-freak, clustered C.8's were the only way to go. Significant Bertha yet, practically by no means co-operated. 1st, 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 distinct back then, plain nichrome and not the squib.
Lift-off frequently involved only a single or if you were lucky, twin-engine power. Huge Bertha would veer wildly off the pad. The older version of BB freqently had a payload compartment. Heaven assist you if there had been live animals on board. Major Bertha also exhibited one other advantage - it could bounce back from prangs with minimal harm.
Yet, there were rare occasions when anything went ideal, and BB was a factor of beauty. It was worth the difficulty.
I appreciate this opportunity to walk down memory lane. Significant Bertha is nevertheless basic to make, and is readily customizable at modest 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 entertaining and the basis of new memories, but new rocketeers have no notion what they've missed.
