4. ### Any Experience with Tube Launching model rockets?

Hi everyone! I'm going to be working on my Javelin missile model rocket soon! The launch tube computer will be controlled by a arduino uno to follow a launch sequence. The idea is to use Co2 to pressurize a 3d printed piston that houses the ignitor to push the vehicle. Then it'll eject the model...
5. ### K-9 Model Rocket Landing Legs

Hi everyone! I got a lot of request to open source my landing leg system to soften impact and perhaps even help to propulsivley land a model rocket. Tell me what ya'll think! I love feedback. These were based off of Joe barnard's design. I need to update the leg section on my website...
6. ### How to use Liquid fuel in a standard model rocket

For a project for my world history class, I'm supposed to complete standards about the progression of technology and the development of rockets and nuclear warheads. My plan was to build three. One for the types of fuel during the cold war (still working on) 1 for between the cold war and the...
7. ### Bottle Rocket Project [Help]

Hello! I’m currently doing a project for my Science class. Basically, we have to design a rocket from water bottles and try to make it have the most airtime. This includes from the time it launches to when it falls on the ground, parachute deployed and all. I’ve done a lot of research but...
8. ### Possibility of 3D printed rocket components

Hey guys, this is my first post here and my first excursion into model rocketry, so if you have any resources you think would help me out, let me know! I've wanted to build a small-sized rocket since a few summers ago, but only now am I actually considering going through with the task in a...
