ok, then my second thought ask (the people that dropped it for you) about the air vents.

He said it assumed its normal path and didnt even know there were air vents.


I dropped it, and air vents may have been there, I couldn't tell. It did show signs of gettin hit by air at one point, (a bad, quick wobble that quickly stablized) and some other teams all drifted the same direction. Other than that it looked normal. Slow and steady falling, it didnt speed up, but at the same time it looked more like 10 meters than 15.

Also it got nearly the same time exactly as what we get when testing with a 9.6 meter drop.

Don't know but almost all of the ones I watched were obviously using parachute drag and not auto gyro. One that was well over 10 seconds rotated maybe 10 times on the way down. Almost all of the top ten would have been tier 2 at our state. They probably should change the name to parachute egg drop.

They need new, unbias, event supervisors next year for rotor egg drop. Last year I got first for this event at nationals, and they some how knew that. They were not taking anything I said seriously, and they were like, trying to tier me. My blade would easily have gotten first this year, but they said that my rotor (not even close to a parachute) was a third tier rotor, which kind of ticked me off. I asked them to give me 5 minutes, to literally, re-build the whole thing. The event supervisor, knowing that I won't be able to do it, said yes. I managed to pull it off, my new rotor being half the size of the old one. Even though they tried to tier me, I managed to get 11th... which isnt very good...
1st for rotor egg drop at nationals 2011-2012

I'll essentially repost here what I put in another thread when a similar statement was made about another event supervisor:

Wow... are you seriously implying that a LONG TIME NATIONAL EVENT SUPERVISOR is in this purely for the ego and thrill of playing 'gotcha' with kids just to impose his viewpoint? If so, I humbly suggest you review the Science Olympiad code of ethics printed on the back of every rules manual and online at http://www.soinc.org/ethics_rules and in particular rule #1. The event supervisors don't have a dog in the race regarding individual teams, and generally err when possible on the side of the teams while ensuring as level a playing field for everyone as possible.

Now, for some actual data: There were NO teams that got over 10 seconds of descent time. The average time across all teams was 6.14 seconds. 37 teams were in tier 1 and the majority of the rest were in tier 3.

You connot assume that just because it gets a good time it is illegal, we have been to five competitions, we never got tiered, and we got top ten.

I just want to say that our team got 37th in egg drop at Nats, we dropped our rotor egg drop, and it caught on the third balcony so didn't drop the 4 balconies height, instead it dropped one balcony height. So our time was horrible. We asked the judge for a retry, but he wouldn't let us. I'm not complaining that the judge was unfair or biased, because I am sure he interpreted the rules fairly and accurately. Also, after discussing, our team decided not to complain. But if we had complained, do you think we would have been able to get a retry?

Our teams did not go to nationals, but we had long discussions of how the ES might interpret the "parachute" rule.
I would hope that it would get better definitions for 2014. Our teams will gladly live with any understandable definition.
It might be minimum revolutions per foot, or chord length or height of the camber or ?????
