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.

I am finally getting around to making one of these. Got a couple questions:

1. Is there a option for apogee deploy?

2. Have you considered a LCD readout?

3. What's for supper? :wink:

I got all the parts on order hopefully they will be here soon! Thanks for the wonderful design!

The deploy can be set for apogee or up to 30 seconds delay past the apogee point. You can deploy either a servo or use the digital output to control you own deploy circuit. The idea of an LCD would be cool, but we were trying to keep the cost down. Most people would just buy an off-the-shelf altimeter if the do-it-yourself version was not significantly cheaper. If the price becomes close to equal the only great advantage to our design is the servo deploy output.

Let us know how the build goes!

I was going to build it yesterday, but the post office decided that I had to pick up the box with the MSP430 at the counter, which of course was closed.

I got the rest of the parts though! Hopefully I can put it together this week.

Hi
Is there someone who knows how to write the apogee deployment on an arduino? I couldn't find the parts for the altimeter like you guys made it. and we also want to save it on a sd card

question about 3d nozzle

Post by beginingrocket » Tue Mar 31, 2015 9:55 pm

hello us water rockets im new and I am wondering if you can put in a downloadable link to get the nozzle and so I can print it with my schools 3d printer they said they might let me use it and I also been wondering if you could sell me a nozzle you can make some good money by doing that and please check out my first 2 stage rocket and tell me if there is a flaw

Good project.
Hope to provide more pictures.
Too many words.

Hello,
I was wondering if someone could help me build a water bottle rocket that stays in the air for 15 seconds. Carries an egg and that is a 1 Liter bottle rocket.

The rules to this event are in the pdf link below:

Thank You!

It has been 10 years since U.S. Water Rockets set the WRA2 World Record Altitude for Water Rockets.
Join us in two weeks for a very special announcement.

Hi U.S. water rockets. The link is not working...are there any news? Or maybe some new projects for the altitude record? It would be nice to see you back on the top!
