Its obvious from the complexity and detail that there was plenty of work put into building the wrocket and launch Tue, 07 Jul 2009 13:02:33 GMT Todd http://groups.yahoo.com/group/water-rockets/message/9734 http://groups.yahoo.com/group/water-rockets/message/9734 ... Hi Gazza, thansk for the ideas, its a simple change to test it with the bottle forward, so we will give it a try on the next run :) -todd- HHWRSA Tue, 07 Jul 2009 12:58:24 GMT Todd http://groups.yahoo.com/group/water-rockets/message/9733 http://groups.yahoo.com/group/water-rockets/message/9733 ...

I was looking at some RC drag cars and the ones with the highest speeds (160mph+) are shaped like that, like top Mon, 06 Jul 2009 22:09:37 GMT George Katz http://groups.yahoo.com/group/water-rockets/message/9732 http://groups.yahoo.com/group/water-rockets/message/9732 Hi All, We've had a bit of fun this weekend launching the big 2 stage rocket. After all the weather and launch site construction delays the weather turned out Mon, 06 Jul 2009 22:01:38 GMT GARY DARGAN http://groups.yahoo.com/group/water-rockets/message/9731 http://groups.yahoo.com/group/water-rockets/message/9731 Test looked like fun for the young fellow. A good excuse for being a big kid. Have you tried moving the bottle forward to place more weight over the front Mon, 06 Jul 2009 17:42:32 GMT Ruben Frances http://groups.yahoo.com/group/water-rockets/message/9730 http://groups.yahoo.com/group/water-rockets/message/9730 Hi George, Thanks. Yes I'm too worried about the actual delay time. I'm not sure it's going to be enough. I can always add an extra damper. I'm sorry I can't Mon, 06 Jul 2009 13:50:25 GMT George Katz http://groups.yahoo.com/group/water-rockets/message/9729 http://groups.yahoo.com/group/water-rockets/message/9729 I haven't finished writing up the variable nozzle experiment yet Ruben. We did some follow on tests a few weeks ago to try to determine more accurately the Mon, 06 Jul 2009 13:35:44 GMT George Katz http://groups.yahoo.com/group/water-rockets/message/9728 http://groups.yahoo.com/group/water-rockets/message/9728 hi Ruben, Good work on the delay mechanism on the magnetic tumbler. I like how you solved the problem with the delay. Originally I thought that you were going Mon, 06 Jul 2009 13:20:42 GMT George Katz http://groups.yahoo.com/group/water-rockets/message/9727 http://groups.yahoo.com/group/water-rockets/message/9727 Hi Todd, That's a really nice video and write up. It's great to see the different tests of what works and what doesn't. Some of those drives went really well.
