Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Thank you USWR!

We have cameras temporarily installed to cut viewports and the servo is now in place. The servo arm is acting as an internal door latch directly instead of using bands across the outside of the door.

The internal door latch system can be a great modification. It is always a tradeoff between how hard a system is to build versus the ease of construction. If you make a system with a lot of precise moving parts, people are unhappy if it crashes and has to be rebuilt. The rubber band systems are a lot less work to repair in a crash, so we steer people to those ideas. A completely internal system is a great project for people who want to take it to the next level.

Just curious, what does SPEW mean?

So this one has not launched yet unfortunately due to other priorities, but I think we will be able to this year.
