Rotor Egg Drop B
Re: Rotor Egg Drop B
I have a question and a comment.
When attaching the cup to your device, are you allowed to tape over the top of the cup so the egg doesn't fall out? I'm thinking not, but we have had a fair amount of eggs fall out of the cup and trying to prevent that.
Secondly, I saw some suggestions that you have a cup on your device that you slip the cup the supervisor gives you into it. I don't see how this can be legal since the provided cup would NOT be the first thing to touch to floor -- your cup would be.

Re: Rotor Egg Drop B
Usual caveat, this isn't the place to get clarifications, not official, opinion only, blah, blah
Given that weight is your enemy, why would you WANT a double cup, legal or not.
If I remember correctly, tape is to attach device to cup, so probably doubtful on legality to hold egg in. But that would really depend on your event supervisor.
Now, it wouldn't be all that hard to build a lid into your device so you keep the egg in the cup. Make a simple X with 1/16 balsa sticks, slightly larger than the cup top. Run 4 strings from the bottom of your rotor system, tie them to ends of the X and then hang down a couple of inches. Tape strings hanging down to sides of cup so X closes the top. Simple, lightweight, no issue with rules.

Re: Rotor Egg Drop B
I wonder if people are confusing the two-dimensional diagonal that would occur if the device was oriented in a flight-ready position (giving a diagonal length of a little over 72 cm) with the three-dimensional diagonal between two opposite corners (giving a length of 90 cm).hogger wrote:If you look at the national website in the rule clarification, it says that the rotor with length made to fit diagonal of the 51x51x51 cube is illegal. The proctors should have instead put that device in at least tier 3?ckssv07 wrote:I was just wondering because people were making rotors that went across the diagonals of the box, but they made a rules clarification that you have to measure it when thebox has at least one face parallel to the ground. Because of this most proctors make you drop it diagonally

You could cut the bottom out of a cup and pre-attach it to the device so you can slip the egg cup into the mounted cup at the competition. This would add very little weight and would require little tape.
Also, par.3.c states the tape can be used to secure the egg and cup to the device and 2.b to seal the bag. So it looks like tape can be used somewhat liberally if needed.

Re: Rotor Egg Drop B
I just finished states and I managed to score a 5.09 sec drop from about 6.5m high... that wasn't what we were hoping for, yet we blew the other competition away by about 2.5 seconds. I was wondering if anyone had an idea to lighten my design and if so please msg me.

If it is true, then it is really good. But, I have Never seen a team that had a time of 6.1. It's sort of unreal.

Re: Rotor Egg Drop B
It's against the rules, because it has to fit in the cube in flight position. Mine was 70cm x 70cm, and it only fit in the box if I tilted it, while bending the wings.If it is true, then it is really good. But, I have Never seen a team that had a time of 6.1. It's sort of unreal.

You did not know the rule? This specific violation has been discussed here and posted on national clarification faq.Cade wrote:It's against the rules, because it has to fit in the cube in flight position.

Re: Rotor Egg Drop B
I believe that you cant tilt the device in any way, as long as it is flat. So then you could get a 70 X 70 device, however it would do best if it was square.
