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.

creating unstable launches?

I was launching a 2 liter with an air tank hooked up to the launcher, and it seemed like the launcher reserve tank volume was kicking the rocket into a spin after it cleared the launch tube.
Did not see the same effect with an FTC..........yet.


Each time we removed the tank and resumed normal operation, the launches were fine.

Sorry, we can't help you. We've never had reason to experiment with reserves. If your results are typical, then it is a good thing we never used them. We have a very narrow range of launch angles that we can fly, otherwise we land in trees.
