Thank you, RoverDude! I have started loving Sounding Rockets as the "model rocket simulator" inside my "cartoon rocket simulator", so I look forward to every new update. I'm glad to see you're using slightly slanted fins on your rocket. After watching real-world NASA sounding rockets, I noticed they use tiny thrusters just after launch to start them spinning, but this doesn't work as well in KSP. So I went with slanted fins, and they work reasonably well at helping keep the unguided rockets on track.
