I've tried a hand pump, a 12 v compressor, a 120 v compressor with a 1 gal tank, and an 11 gal tank filled by the same compressor. I'm looking at switching to...

Apollogies for the late reply. I don't have any experience with CO2 or paintball, but can try to address your second question: How many launches you get from...
Thanks, George. Reading the reviews of the paintball tank/nail gun regulator, it seems some people had reliability problems. I'm considering something like...
This was mylast launch, after almost one year. This time the rocket carried an altimeter and a camera on board. I made some attempts, some successful and...
That's a nice find on the adjustable regulator. 0-200psi is a great range for water rockets. :) Though the price tag on the more advanced adjustable model is a...
Congratulations Bolivar on your new altitude personal best! It looks like the whole team had a lot of fun on the launches. What altimeter are you using on your...
Hi George, Thanks for the tips. In the next launch will see if I can make these corrections. The leak occurred due to a problem of the quick release spring,...
Sounds like a good plan without being too expensive. If you want finer control over the final pressure with the fixed pressure regulator, you can put an...
Hi guys, Over the last 8 months dad and I been working on an all-fiberglass rocket called the "Shadow". It has a capacity of 5.8L and is 60mm in diameter....
Thank you so much for working to bring all that detail to the web. Your rocket was awesome. Your pressures are fantastic. No wonder you set records. Sorry...
Thanks Henning and Mike, Though crashes are always dissapointing, I find it interesting to at least try to understand the root cause of what went wrong. A...
Hey guys,What about if you had a pressurised container in the noscone section pushing out a piston and thus no more need for BP. Just an idea and then you can...
Back when I was still flying I used a speed-flap arrangement but as the rockets got slimmer and faster I researched Soper-Roc and went for gliders ... but in...
This approach certainly has some advantages, but also some minor drawbacks. I believe several people have used a similar approach in water rockets already. You...

There are two common all mechanical approaches for parachute deployment. Have a look at Dave Johnson's air speed flap concept. The original webpage is no...
Alas, my original web page is no more (I finally ditched earthlink/mindspring). I still have the source files, of course, and one of these days I'll get around...
We have had great success with the air-stream flap. We even had to modify it so it had no metal parts. You have to engineer it so the nose cone does not jam...
Hi George, Yeah. The reason for the piston approach was partly to protect the chute from heat partly to drive off the nose cone cleanly and partly because I...
