I had some fun this afternoon launching my new Vesta II rocket for the first time.
No recovery system yet (besides NOAA -> hope and pray ), although it is designed to use an in-line deployment system like the one from AirCommand water rockets.
Inaugural launch:

Basic Specs:
Volume: 3.35 liters
Fill volume: 0.88 liters
Height: 79 cm
Diameter: 9 cm
Dry Mass: 196 grams
Nozzle: 9 mm Gardena
For a little fun, I calculated the theoretical Isp of this rocket, which is about 3.02 seconds.
Cu plăcere! I'm glad you enjoyed them. The bottles are just Robinson-coupled base to base with some clear silicone sealer in place of the o-rings. I have a prototype electrical timer circuit that works with a dc motor for deployment, but it's not ready for flight yet.

In-line deployment systems are the best. We've never trusted any other type of parachute system. The dual deploy parachute system we created in 2004 was dual in-line parachutes. One chute deployed out from below the nosecone and the other was deployed below the electronics bay. It was a good system but we eliminated to save weight and decrease our setup time so we could get in 3 launches within the 2 hour time limit for world records. It's cool to see you guys trying some of these same experiments. If you have any questions about our system, feel free to ask.
