I remember when my now late father helped me build my first Estes rocket as a kid. Now, as a father myself, I'm handing that down to my little one. Kids love rockets 🚀 and I actually work in aerospace now, so yes,... very inspiring hobby. Big big bang for the buck... great video series!
The original Berthas had balsa nose cones and a longer engine tube,which traveled about halfway up inside the main body tube. This helped to pressurize the ejection charge much better so chute failure was kept to a minimum. Since they changed the engine mount tube to a standard 2 and 3/4 inch tube,parachute failure is much more frequent because there's so much more area inside to pressurize.
I really did like the older kits better. Getting that nose cone to be a perfectly smooth surface was a point of pride. You are absolutely right about the engine tube length.
I recall the original Berths. Think it was stripes on the package. Nice flying kit. Think 3rd launch had shock cord failure or engine ejected (in the 70s). Estes wasn’t on the engine hooks til they bought out Centuri. And Big Bertha became a lovely lawn dart buried 4-5” deep. What can ya do. ¯\(ツ)/¯
Sort of. If they get wet for a while in the rain and you bump them they might tear. You can always apply a light coat of clear acrylic spray paint to help protect them.
My uncle got me addicted to model rocketry, and ever since, i have loved all of estes rockets and i love how shiny and reflecting your rocket is😊
Thanks! They're just so much fun.

It's so much fun! AND you learn about physics.
Yep. i am addicted in aeronautics
Love watching this. I built and launched Big Bertha with my late father in the early 1970’s. It is an absolute legend.
Great Video. these Cliff hangers really keep me hangin' on !
More to come!
Thanks for your time

Quite the unusual hair dew. I am glad you like it, lol
Great paint job!🚀
Thanks! 👍
Good to see ya,
Loving it.
Let’s go Dino!

Great video
I missed how the nosecone goes on, the parachute was put inside? the shock cord attached? I never built one, so I don't know the process
Are the decals weather proof?

I built a big bertha probably 50 YEARS AGO. I built another 20 years ago still have that one. painted them red and black
