The recovery section is obviously permanently mounted to the main stage. The instructions indicate the nose-cone assembly should be glued together.

How the instructions show the assembly.

Apparently the way to make the 'short-stack' is to sand the plug and internal diameter of the nose-cone to a snug-fit,

Then use masking tape to ensure a snug fit with the payload bay when necessary.

Valkyrie recovery systems just came out with a spool rocket. Check it out here https://www.valkyrierecoverysystems.com/store/p33/Spooligan_Rocket_%2APre-Order_Now%2A.html

This is one of my favorite level 3 rockets that I've seen... https://www.youtube.com/watch?v=4QsEPEhq5yk

Any way to repair dented cardboard tubes?

I have a crossfire isx Estes rocket and the parachute sometimes doesn’t deploy not even the top. I did every step correct building it and it deployed one time a year ago but not this year. Why?

Hey I’m a teen from England and Ive never done this before but I’m really interested in it. I have been wondering is this legal to make a rocket and launch in England ?

If I use latex gloves, and protective glasses, go outside, and use a level 1 (surgical) mask and am there for less than 10 minutes, would that be okay? And what protection do you use?

It uses a Estes D12-5 Rocket engine, and both of the cardboard body tubes weigh 58g each, the nose cone weighs 38g in the simulation but I have to work on it a bit more, It uses a Estes 18 inch PN 2266 parachute, but did I do it right? If not, any tips to point me in the right direction?

Here's the plotted sim as well

Do y'all ever make Co2 cartridge powered rockets? If so, any tips?

This is a the satellite and transition/reducer that was used in two Estes kits listed below.  All measurements were taken from the part in an Estes Geo Sat LV kit.

I massed my rocket and created a simple pendulum (see picture) to take the necessary measurements to calculate the rocket's moment of inertia. For context, I'm trying to create a thrust-vectored model rocket which is why this is important. I just want to clarify that the equation I am using to calculate the moment of inertia is correct, because it's been a hot minute since I've taken physics:

This is what I was planning to use:

I = (T^2 * mgh)/(4pi^2)

Where I is MOI, T is period, m is mass, g is 9.81, and h is the distance between the COM and the string attachment point. What do you think?

I recently assembled my TVC model rocket, and I'm hoping to do a test somewhat soon. I was planning to get an Estes F15 motor for my flight, but I'm a little confused on how to make sure there is no ejection charge. The avionics bay sits directly above the gimbal mount, so any ejection charge would damage it (planning to deploy parachutes using flight computer). Do I just buy a F15-0? Or do I do something else? Because I thought that the F15-0 still has an ejection charge.

For an ad campaign (I can't say which company) I am tasked with launching a beer as high as possible. I am exploring options with trebuchets and potato-style air launchers but the brand has expressed more interest in using rocketry.

This isn't a troll post. I want your honest opinions on how you would go about doing this in the simplest/most affordable manner. Brand is located in Canada

Hello all. I’m going to start exposing my kids to model rockets. They are working on building small Estes Bandits (model 2435) with A3-4T engines.

I am curious if the park near our home would allow enough space for this small rocket. Or do the smaller ones have more drift with the umbrella, because they’re lighter?

Below is a link to the google map view of the park. Hopefully that helps.

Thanks for any advice.

Hi all .first post here .. I'm slowly getting my kit together, I used to do a little rocket launching as a child but has so much fun I needed to .. revisit my youth .. I have a tech question tho if I wanted build my own rocket motors is there any reading material that can be recommended ..?

Thanks in advance

What's going on guys? Here at Hydrazine Design we've designed a new nose cone STL published to Thingiverse for you to download for free and print them on your 3D printer.

This is a nose cone for several kits produced by Estes in the past and are listed below. It fits Estes tube size BT-60. Dimensions are taken from the nose cone of an Estes Geo Sat LV kit.

On the launch pod there is a long stick attached to it that helps rocket to fly to that direction, but unfortunately it got broken in my case. What would happen if I launch it without it? I still have part of it on the launch pod but only 30 cm of it. Which is a little longer than the rocket itself. In case it won’t work what can I use to replace it?

Do you think 2mm plywood will hold up like the fins of this rocket, or what wood would hold up?
