AboutJames Bell Expertise 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.
Experience 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.

Answer Donovan -
I am a huge fan of using electronics to assist me in a successful launch and recovery. I would suggest you look at ADEPT ROCKETRY (http://www.adeptrocketry.com/stagers.htm). They have staging electronics for up to three stages. I have never used these particular models, but I have nothing but good things to say about their altimeters.
