One of the most challenging aspects of water rocketry is the design and operation of a reliable recovery system. Once you have mastered a working design that works every time, a whole new world of experiments opens up for you. You can fly altimeters and cameras without fear of breakage, or you can launch other experimental payloads or sensors nobody has even considered. You may even choose to use the system to compete more effectively in egg-lofting or flight duration challenges, or perhaps even use it to qualify for a WRA2 World Record!

No matter your requirements, a reliable system that is affordable and easy to build has proved to be a hurdle that many people are frustrated by. We at U.S. Water Rockets felt that it was time to tackle this daunting problem with innovation and out-of-the-box thinking. We came up with a solution that we believe everyone can use!
Due to the enormous support and encouragement we have received from our friends and outstanding members of the community, we have released our idea as a FREE firmware package and schematic diagram which anybody can use to create a recovery system like the one shown below.
To create the ServoChron(tm), you only need the MSP430 Launchpad, a Servo Motor, a LiPo battery, and a switch to detect launch. We have a tutorial on how to make an ultra lightweight launch detect switch.
