Congratulations on breaking 2000! That is really impressive guys!

I thought you said you were building X-16. Why did you set the record with X-12 again? Did you have a problem with the new rocket???

[U.S. Water Rockets1]

Thanks Tim,

We replaced a lot of components on our launcher with new higher pressure rated ones so we decided to test it before launching X-16. When the first flight hit 2068 we decided to fly a second flight and set a new record using X-12. Since the class A rules require that we use the same rocket for both of the averaged flights we had to use X-12 agaiin.

Wait until you guys see what X-16 can do. Heh Heh

Are you guys ever going to get something off the ground?

[Drag_Racer408a]

Well i am getting ready to get somthing off the ground if anyone cares. Haha.

Looks great. Keep up the good work you guys!

BTW, how did you manage to reack the rocket while zoomed in that 3rd video? It's 10 times better than anything I've been able to do.

[Team Seneca]

As Darth Vader would say: "Impressive".

There might be some logic in changing focus to the class "B" or "C" records for us. I still think your approach is losing too much energy to drag. My way is a lot more efficient and doesn't need all that composite just to keep it together. But, I'm pretty jazzed about multi-stage right now.

Rick,

"reack"? You mean "track"? We have a variation of a camera boom that we made over the winter. It's in the experimental stages because the rocket goes so high that it is still virtually impossible to keep it in-frame. We're addressing that issue, but as you can see we have a few bugs to work out. It still managed to make a reasonably good video.

People use these things all the time for R/C planes and rockets.

Who witnesses launches to ensure compliance with safety rules.

Currently, either secretary of the WRA2 or I "inspect" the rocket. Either by seeing the actual rocket in person, or by seeing a few photos of the rocket in cases where physically being near the rocket to see it are cost prohibitive. We respect the privacy of our competitors and that of any witnesses. We have a public review of the videos and altimeter data on this forum as well. Submissions of names of witnesses or design specs are welcome but not required.

This contest is supposed to be a friendly competition, and there are no great stakes to be won by cheating, so we allow a bit of leeway and rely on our competitors to be honest in their descriptions of their designs. The honor system will previal until we have been given reason to change. We have a lot of members who are very well versed in various aspects of water rocket design and if anyone submitted a design that was questionable, they would surely point it out.

If that ever happened, we would perhaps ask for some supporting evidence.

Thanks for your question. We are looking forward to your participation. Please register for membership in the WRA2 if you wish to compete for our prizes.
