This is it! Big Bertha takes a flight along with a few other rockets.

Been building and flying model rockets since 1972. I have never tested a model built from a kit. I always assumed the manufacturer of the kit did, and if it was properly built, it was already properly balanced and ready to fly. I now design and build my own rockets. I always put talcum powder on the parachute before putting it in the rocket, to prevent the plastic from sticking to itself.

Used to fly those back in the day. i had Big Bertha, sidewinders, and others. The Sidewinders were awesome doing their rotations as they ascended ! I still have a four place launch pad and firing box I built.

Great fun to watch this adventure. Tinkering and learning about building my own rocket motors here Downunder. Fun little hobby I must say. 😉

Good job Doc Brown. We now know how craters are made on the moon.

As a kid I had a two stage rocket. It was Estes, but I don't remember the rocket name. Anyway, I launched and it went sideways. It angled towards the ground when the second stage fired directly over a rural rd. Well, the rocket was obliterated. Stuff of life. And I always cut holes in my chutes. Used streamers sometimes.

We followed the part 1 and part 2 to build, but now we stacked to put the engine in because the medal hook in the engine mount block it

B Bertha can be built as a payload rocket. A 3.5 oz payload to roughly 1300' on a d12-5. For better results use a 15" chute.🙂

I had a Big Bertha style rocket that had the clear payload tube section. It wasn't the Big Bertha, but the same design and size...little longer. Silly story, the kit came with an illustration of a child putting their pet Gerbal in. It read, "Turn your pet into a cosmonaut". I kid you not. So I put in some Gypsy moths from a nearby tree as a kid. They came back as green goo in the bottom of the payload tube. 😢

How high did Big Bertha go? When I was a boy, we would balance by hanging the rocket by a string at its COG and point into fan/blower of a wind air conditioner. But I thought we were testing if the fins where straight. This was 50 years ago.

About 800 feet.

Very nice explanation of the CG/CP as related to stability. The Big Bertha is a great park flyer. The Proto is a nice looking rocket also. The X-15 seems like a tough one to fly correctly, you've done a very nice job 3d printing it. Did you make the decals on this one? Very nice job! Look forward to seeing to future rocket builds.🚀

@HackaweekTV 2 жыл бұрын

Yes I found a decal sheet image in Google then printed them out on some adhesive vinyl. Very pleased with the final result. I may try launching it again with a bit more nose weight and a higher thrust "A" engine.

QUESTION! I just found your CB750videos, awesome!! The Hondabond you use- is it the high heat HT stuff or regular blue-and-white label stuff?

@HackaweekTV 2 жыл бұрын

Blue white as I recall.

@keithkrause3386 8 ай бұрын

Wasn't the x-15 nose heavy? More weight in the back?

@albert_vds 2 жыл бұрын

X-15 is more of a glider so maybe an angled launch would be better. That might not be allowed? Or the rocket motor is too powerful?

@4seasons4handlbars 2 жыл бұрын

Any chance you still have your CB 750 carbs? I need a carb body for my 1973 Cb750.

Why I don’t see the engine mount with the medal hook when you insert the engine into the body tube?

@BillKurn 8 ай бұрын

The engine mount simply works as a spring that bends out of the way and then snaps back when the engine is inserted.

professor dino, have you made a diy rocket engine ?

Nope. Might try sugar rockets one day though. Could be BADASS!
