I am a member of Tripoli Rocketry Association, and am certified to fly hi power rockets. I can answer questions anyone may have about design, materials selection, stability calculations, motor selection, altitude and performance predictions, and parachute and recovery options.
I make my rockets from existing kits or parts readily made through commercial channels. I do NOT make my own motor propellants (they are challenging enough even for the companies that do this for a living), and I do not advocate making rockets using "typical household item" such as paper towel rolls.

Justin - I can't speak for cell phones as I am not familiar with the various brands and their features. Most model rocketry entheusiasts use trackers designed for the task. http://www.adeptrocketry
Dear LM - I will admit I am not familiar with the concept of bungee cord rockets, but I did look them up through a variety of web sources. In essence, I think the main thing you are looking for is
Joseph - Have you looked into AdeptRocketry ( http://www.adeptrocketry.com/)? They have altimeters that can stage ejection charges. I have one that goes off at apogy to break the rock in two, making
Jarett - There are three ways you can calculate a rocket's maximum altitude. I have examples listed on a webpage I set up for rocketry: http://id3433.securedata.net/bellhomeworks/home/tips.html
Thomas - The Estes Interceptor "G" is the big brother to the Interceptor "E". As the name states, it is designed for a "G" motor. The minimum specs I have seen for it are an F62-4. I don't know the
