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.
Question We would like to use a fin can for a 3" body tube with replaceable fins. Any suggestions on where to buy?
Answer Esther -
My apologies for not getting back to you sooner. It appears my Spam filter is working overtime.
I have never worked with fin can's, so I don't have any personal preferences to provide you. But, I do have a web page set up with many links to a variety of online rocketry stores
