I like all sorts of rockets including odd-rocs, scale rockets, unique rockets, spectacle rockets. I like jet rockets, sci-fi rockets, and I love futuristic hypersonic planes.
But sometimes I just want to put a big motor in a rocket and send it.
When I got my Level one last year, I had several goals in mind. Besides just having fun and launching rockets, I wanted to accomplish some other goals:
I started by weighing the contents and running simulations. I don't want the rocket to just dabble in the transonic zone, but I want to pretty decisively and unambiguously exceed Mach 1. So I'm shooting for 1.2+. Already just weighing the parts and electronics I plan to include puts me at 20 oz, which would require a pretty thrusty "I" motor to hit Mach 1.2. I will try to find places to save weight, without sacrificing significant strength.
Simulated maximum velocities (in Mach) with some random motors and rocket weights.
Already 20 oz, with tracker, Eggtimer Proton, batteries, and AV bay parts!
This should be a fun challenge.

When I got my Level one last year, I had several goals in mind. Besides just having fun and launching rockets, I wanted to accomplish some other goals:
- 1+ mile Altitude, achieved with Mach 1 Rocketry Alien Interceptor. (This was easier than I thought it would be.)
- Air start at least one motor (partial sucess with Skunk'd). I'll attempt this again.
- Mach 1+ velocity. This is turning out to be a bit harder than I thought.
