Re: Bottle Rocket B
Clarification on the stuff in the wiki: I would not pay attention to any of the rule stuff it mentions except two liter bottles, and the not changing configuration. Eventually I will get around to fixing the rest of the rule stuff in it, but I don't have time right now.

Re: Bottle Rocket B
I don't think they'd ban backsliders and parachutes in the first year of the event. Maybe one or the other, but I think they might take pity on the competitors this year (especially since it's Div B and people wouldn't have competed in a rocketry event before) and decide to ban all that stuff next year.

Re: Bottle Rocket B
My earlier comment should have been change in shape, which wouldn't ban backsliders.

Re: Bottle Rocket B
In the last few weeks of high school my school's physics class made bottle rockets, and because I had been my own science Olympiad class I decided to make one too. The model I made was crazy simple and was literally like a missile went straight up and strait down with a lot force (bounced a good 7 feet when hit the ground). The model went according to the teacher’s calculations around 125ft all I did was took two 2L bottles and cut the top off one remove the cap and the neck of the bottle and attached it to the pressure vessel. What was key to both to get go straight up and down was the amount of weight I put in the nose of the rocket, if some wants to try this simple design it can be properly weighted to the point that it fall on its side thus giving a decent time. I may post the pictures of the rocket some time if I can ever find them. Two words of wisdom if anyone try’s the design it will take a long time to get correct but will be more consistent than any paper cone rocket that could be destroyed after any test thus having to make another cone, and fins can realy make it spin A LOT if aligned correctly thus allowing to travel strait up in the presences of wind.
I really want to find the pic’s I took of it, I named it The Predator, because the I thought it would be more fun to see my rocket come down like a missile like in Call of Duty. If a parshoot or like device are banned side gliders probably going to be what most rockets will become. I think use of plastic bottles is better than paper that is very weather dependent [rain, humidity can be catastrophic for these cones], I seen one at regionals sheer to peace’s when it was launched because it was raining and windy.

Re: Bottle Rocket B
If anyone has the rules yet, can you tell us the answers to some of these questions?

Re: Bottle Rocket B
all of my statements have been based off the draft rules I saw. I am being vague so that if they change I am not totally wrong >.>

Re: Bottle Rocket B
Here's a new twist: Para. 3.g "Rockets may not change shape or deploy any type of recovery system."
This would seem to limit rockets to some type of backslider/glider.
Other parameters:
.....1. 1 or 2 rockets
.....2. 2-liter bottle
.....3. Blunt nose/minimum radius
.....4. 75psi
.....5. May not change shape
