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.

Launchpad altimeter

Post by kitestring » Sun Nov 15, 2015 1:59 am

Hi, I have built a launchpad altimeter and want to delete all memory and REINSTALL the software from scratch. I had used an old servo and when i turned it on, it went crazy ... so i turned it off. Tried another and same thing. Board seems fine though. Thought if i used a new servo and tried again would be OK?
Any help appreciated.
