Well, winter's approaching so I'm thinking about my level 1 rocket for next year. I've attached some pics and I'm hoping to get some feedback on a couple of things that might be a problem.
First, the rail buttons will need to be on standoffs. The "payload" section is a 3.9" tube and the booster is a 3" tube. I was thinking of using well nuts to attach them and hardware store nylon spacers for the standoffs. Any idea if this will be rigid enough?
Second, it is a bit overstable. Not sure how much of a problem this will be. With certain 38mm motors installed, RockSim and OpenRocket show about 3.5 caliber stability. I've made the fins a bit smaller, and that helped a little. I thought there might be something about this design that made it over stable, but it could just be the length and the weight of the nosecone and transition.
Any comments are appreciated. Thanks for looking!
