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

Since our founding in 2003, we've become 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.

I posted a personal best as designed by my friend kevin and I. I did paste the thrust imformation from a simulator because I thought they were reliable. This might be wrong.

Repliglorandrockets. As I said, the altimeter may be wrong. As stated the rocket hit the ground at highspeed. Also I have check this altimeter with a estes altimeter and they read differently by about 80' when the GPS said we were at about 500' above start point. The second stage valve did not let air to the second stage so it failed but did release.
Can you answer my question? How are you preventing the FTC booster from bending at launch? Some kind of reinforcement?

I was not having much bending trouble with bending but I found that using wooden dowels helped reinforce the FTC.
