    Hi from Denmark

    Hi all I am a 50 year old guy, who has been flying small and simple rocket models with my son. Now I have bought a Mid-power Aerotech Initiator 3 feet tall. So still a small rocket. I don't know about any club in Denmark to small hobby rockets, so if there is any other from Denmark here, write :-)

    I’m sure people have tried this by now... what are y’all’s thoughts on drone recovery of rockets? I see this being helpful for reconnaissance of a property you don’t have permission to be on.. looking around for the rocket. Then maybe even actual recovery by installing a hook and landing on top...

    Using Side Thrusters on a missile to create an angular acceleration

    Assume a rocket is standing on the ground with mass = 1000 kg, and near the top of rocket we apply a force of 100 N for say 1 sec,now assume that this is sufficient to tip rocket over/start tipping over. If the rocket is mid air and accelerating at 30m/s^2, then likewise how much force would be...

    Pressurizing and Cooling liquid fuel rockets.

    Hi! I am 11, and I’m quarantined at home and bored. So, I started building an imaginary rocket! I’m not sure what thread to put this in, so if anyone wants to give me some advice on using this forum I’d be grateful. This is my question: I had an idea, of using helium (does that even absorb a...
