I will be happy to take on questions about low-power rocketry in general, including rocket design, operating characteristics of blackpowder motors, low-power motor selection, rocket construction, aerodynamics, parachute and streamer duration competition, boost glide (and a little rocket glide), egg loft, altitude competition, and scale competition. I can help you with Barrowman stability calculations, but I am not a rocksim user. I know the basics of mid-power rocketry and small composite motors but I don't fly them much (I'd rather stretch my money by sticking with low-power). I believe I can explain many concepts in a way that just about anyone can follow (and maybe even over-explain?). I absolutely do not mind "newbie" questions one bit; the only bad question is the one you don't ask!
I have flown model rockets for some 40 years, including a few early years of NAR competition. I have been active at the local club level as well as in the NAR. I enjoy designing and developing unconventional designs (the kind of thing you look at and say "it won't fly!").

I am an aerospace engineer who has worked professionally in the field for over 30 years. I have worked often with local school, church, and scout groups to lead introductory build-n-fly sessions.

Hi Alan, I don't have information handy on the size of the side conductors, but the Estes-type igniters really only rely on the tiny bridge wire at the tip to get hot. The two leads on the sides could
Hello, Veerendra, It sounds like you have started a very ambitious experiment. I hope you are using good safety practices, and have a teacher or experienced advisor to help build these motors properly
Hi, Dev, I am guessing that when you say "bottle" rocket you mean the kind made from a big plastic soda bottle, that squirts water, and not the kind of bottle rocket that they sell at fireworks stands
Hi Derek, You can make your own body tubes from several different paper materials, and a few plastic ones. If you roll plain old copy machine paper you can make a decent tube (spray one side with contact
Tim, I believe there are plans for a simple launcher on the NAR (National Association of Rocketry) website. Try: http://www.nar.org/NARTS/mahler/ultra.html The Apogee rocketry website may also have
