That's what I asked. And how were your rockets designed?

Winning time was around 28 most of the top ten where between 21-25 seconds. There were tons of 18-19 second rockets.

How was the 28-second one built?

Please take this into consideration when looking at the times:
The timing stopped when the rocket hit the ground (meaning the grass/concrete on the same level as the launcher), out of sight, or it came to a complete rest. The last part is the most important. If the rocket launched up and landed on the roof of a building and rolled down the roof, the time did not stop until the rocket stopped moving completely.

Also a side note. For anyone's rocket that got stuck onto the red roof of the building on the other end of the field. I climbed up there and got them all down and left them at the event supervisors table. I hope a number of people got to get theirs back.

What did the winning rocket look like?

It looked like a rocket, it was red, like a firetruck! My really good friend and her partner built it, congrats to them :D

As in, what were major design elements?

our rocket released pressure at state but they wouldn't put more in

I think 3rd-10th place was all 22 second rockets, if memory serves.

We got 14th with a ~20 second rocket (maybe a few hundredths less or more).

3rd- 10th was not near 22s. We were 3rd with 26. I think 6 was around 24s.

Sorry for the double post, but you need to stop asking this. You've asked this 4 or 5 times. You'll probably see some of the top rockets in the best of 2011 photo gallery sometime soon. All the top rockets pretty much looked the same. Either a long cone or a long tube for the nose. Their fins were tilted or the bottoms of the fins were angled for the rocket to spin upon takeoff. They were all built of the lightest materials possible for max height.
