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.

Parachute (nose cone) deployment mechanism

Re-working a parachute deployment mechanism I thought of two years ago. The servo was binding in the original and unable to release the "dart". Today I realized it could work witha proper sear release.

Seems nice!
But I could use some explanation

Probably like the VDTT but the piston isn't connected.

Nice system!!! But what altimeter were you using? A perfectflite?
