Re: Junkyard Challenge C

Did anyone do a coin sorter for their state competition. I am interested to see what their final score was.

Re: Egg-O-Naut C

If you don't cut a hole (or I have found horizontal slots to work better) then the parachute becomes a ball of trapped air and will descend faster. I think 8 shrouds is a good number for anything smaller than 4' diameter anything bigger I think needs at least 16. For fins I have found for 1L bottles...

Re: Egg-O-Naut C

Hey guys, do you think its better to make the lightest rocket possible or should the rocket have some weight to it? :ugeek: In my experience lighter is better for the propulsion part of the rocket but the weight of your "nose cone"/ capsul should be heavy enough to keep your parachute from rocking ...

Re: Trajectory B/C

The rule, in my opinion, was up for interpretation even after the clarification. If I read it correctly after your first launch your device could be up to 1.5 m long and 1 m wide if it fit before the first launch? Is this correct and if so maybe a better rule wording would be better for next year.

Re: Egg-O-Naut C

Throughout this whole year I have attempted many different designs and sizes. My best time came from a 9 foot diameter circle with 16 tethers. I used .5 mm plastic for material and tethers made out of braided fishing line. Best time of 21 seconds. Bombed at state though. Bad launcher combined with l...

Re: Trajectory B/C

Had Mo. State tournament yesterday and took 2nd place. My total score was 160 1st place was 68. Our distances were 3m out 80cm tall and 9m. Not pleased with results but considering it was outside with irratic wind it's to be expected. Good luck at nats.

Re: Junkyard Challenge C

Just had MO state yesterday. Got first place with our "Tipping the Scale". I was dissapointed that we didn't get to use our coin sorter. The challenge object was a large bolt and nut at about 253.4g and mystery mat was a cd. Good luck to all people who have a team that is good enough to go to nats.

Re: Egg-O-Naut

I won my regional this week with a total time of 42 seconds. Not sure what the next best time was but was intrigued by how simple most designs were.

Re: Trajectory C

I think the rules should be written so that it gives you a minimum ceiling height for each distance. Without that its a total guess as to what your angle of attack should be. The most accurate way to hit a target consistantly would be to launch the projectile high in the air and have it come down at...
