Rocket 13mm

Two rocket variants using 13mm motors. Both eject the motor. The straight fin rocket is more stable based on open rocket calulations but both seem to work well. I've included pictures of the calculations from open rocket. I had one fail on impact at landing as shown in the picture. I used Estes A10-3T engines for launch. It will probably work with 1/2 A3T-2 although I did not try it. It will probably NOT work with 1/4 A3T-3.
