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.
Science, yeah!

Made a new team. 7th place at NH states. Officially the champions of Vermont.

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)."
