Thanks for your effort to educate the masses on rocketry. I have learned a lot from you & so have many others, thanks.

Short, simple and to the point.. You learn something new everyday! Thanks for the great video

Using whichever design program you choose, and finding the necessary nose weight is extremely vital in home designs. But, you also need to factor in the weight of the epoxy (if using BB's or shot), so the nose weight wouldn't be excessive, giving you a different (and potentially dangerous) unstable flight condition for a top-heavy rocket.

I put modelling clay in my rcket as a kid. Used a dowel to smush it to the tip of the nose cone. Been there since the 80s, never shifted. Many launches. However, with a E, F G not sure if itd stay put.

I always use ROCKSIM...great program for building rockets and kits. Nice video as always Tim!

Very helpful information. I launched my first full scratch-build (2- stage) and it got off the rod and flew a hundred or so feet and spiraled out of control. Hopefully, this will solve my issue!

I've used clay with Estes kits, and added the same BB's to MadCow rockets such as my 4' Patriot. with that project it required a large amount of nose weight and I added a metal rod through the nose to give the BB and epoxy to hold on to. Is it normal to have clay, BB's and epoxy together or was your example more for demonstration on you tube?

Great info thanks. I'm yet to see an american cordless drill that sound good quality though

Thanks for the great instruction videos you provide. I am just starting back into the hobby after 50 years away. Back then CP wasn't even talked about with the Estes rockets. Now I discover just how important CP is. I discovered I needed to add nose weight, and this video provided a very easy way to accomplish that. Thanks.

The real rocket science is trying to add little to no dead weight. We can achieve this by making appropriate sized fins that are both as light and as stiff as possible. Ideally weightless

Right. I always encourage modelers to design without having to put in nose weight. But if you must...

@greenlex518 11 ай бұрын

Great video Tim! How do you calculate how much weight to add?

@apogeerockets 11 ай бұрын

As much as it takes to move the CG forward of the CP in the rocket. I use the RockSim software to do this, because it is faster than trying to hand calculate it.

Some epoxies are poorly adherent to plastics. Have you had an issue with it letting go? If that epoxy you used works well, can you specify which one it is? JB Weld makes an epoxy specifically for plastics, I use it to attach plastic (ABS) Estes engine retainers to motor mount tubes.

I haven't tried JB Weld for nose weights. Sorry. Give it a test.

Recently i started making my own rockets just by copying estes kits ive bought in the past..i dont copy them 100% which leads me to my question?how do i determine the number of fins to put on??whether it be 3 or 4 which seems to be thee most common..does it have anything to do do with the length of the body tube or the weight of the nose cone or perhaps both??

The more fins a rocket has, the greater the margin of stability. So if you need more stability, you need to add more fins, or make them bigger. To figure that out, you have to find the CP and the CG of the rocket. For that we recommend the RockSim software. You might also want to see the book: "Model Rocket Design and Construction." You'll find that on our website too.

Well, fins affect the rocket in a few different ways. By adding more fins you increase the mass of your rocket as well as the aerodynamic drag. However more fins also increase the rocket stability in flight as well as move the center of pressure further toward the base of your rocket. Assuming your center of mass stays ahead of your center of pressure and the motor you use is enough to compensate for the additional resistance, the number of fins is entirely up to you! Give the Rocksim software a free trail, play around with the fins and you can get a better understanding of how it impacts your rocket.
