    Rail Exit Speed, how slow is too slow?

    Hi Folks, I'm simming a collection of mid power rockets of interest, and while OR hasn't given me any warnings yet, how slow is too slow when looking at velocity off the rod? 5 m/s? 6 m/s? etc. Thanks!

    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...

    Adjustable Launch Tower Build

    This is my first build thread, so go easy on me ;) I've flown a few minimum diameter rockets in the past, and I typically prefer to build them with four fins. However, one issue I've ran into with four-finned rockets is with regards to launch equipment. Every time I fly one, I have to use...
