Helicopter Egg Drop B [Trial]

[The Architect]

but the people that did said that they got 7.96 seconds

By whose clock? I don't have a copy of the spreadsheet available, but I'm pretty sure there were no times over 7 seconds.

That is correct.

I believe you, I thought that it was a very long dissent time also. I am just relaying what I was told.

[Itsanthonguise]

Any national times? I for a fact had the event supervisor tell me I got the best time of the day with about 7 seconds... to bad my egg broke anyway so I got second teired lol they should really fix that when they make the event rules for next year, especially since I think I deserved my medal :p. But whatever nothing I can do now

Well my dad timed it and he said that the one i made was 5.3 seconds and i got 6th place at nationals

Since there is no standard height from which the helicopter is dropped, these comparisons of time of descent are not meaningful

This event is new and the rules appear to be tentative. I have the following questions :
1. Is it OK to have damage to the helicopter when it lands ?
2. Any restriction on materials that can be used ?
3. Are we permitted to have more than one rotor, one above the other ?
4. Any restriction on number of blades per rotor ?
5. Will the cup holding the egg be supplied by the event organizers ? Or the contestants build it ?
6. What if the helicopter lands at an angle and a rotor blade touches the ground before the (egg holding) cup ?

I have two suggestions :
1. In order to get clearance from walls and similar obstructions, the helicopter could be dropped from the end of a rod,say, about 2 meters long. A hook at the end of the rod could engage a hook or a loop on top of the helicopter. The helicopter could be dropped by turning (rolling) the rod 180 degrees.
2. The rules refer to aerodynamic drag on the helicopter "blade. " A single blade cannot make a helicopter. A minimum of two are required. All the blades in a plane are together called a "rotor." Therefore, the term "blade" should be replaced by "rotor(s)."
