Save the good stuff? Mousetraps only cost about 2 dollars right? And my region is really competitive. Troy's car, which I saw at regionals, probably had a time of about 12 seconds and a distance score of 3.7 cm. It's pretty hard to beat a score of -4.3

I didn't need to replace them in order to have a good vehicle for regional’s but for my state I needed to get some better stuff I remain completive.
Winneratlife: You will not get to do that state I am 100% sure that you will not be able to do have any runs the day of down there. I have gone to State the last 5 years [this year will be 6] and never has that been allowed!

I know it has no official standing, but the National Event Supervisor told us at a coaches' clinic that there was no limit to the size or number of the holes drilled in the mousetrap base.


Really? When and where was this clinic at? How did you know it was the national event supervisor, I tried looking this information up on the soinc website and couldn't find a listing of National Event Supervisors.

But if the National Event Supervisor tells you that it's okay, then it must be okay right (at the very least at the National level)? Since they'd be the ones scoring the event at Nationals.

*edit meant soinc website not scioly.

Well, he said he was the National event Supervisor, and the State Director said he was the National Event Supervisor, and I believe he had a little name tag saying National Event Supervisor, but I suppose it is theoretically possible that they were all making it up. The clinic was in Poughkeepsie, NY, on October 20somethingth.

Alright, so I managed to finish building the mousetrap vehicle, but with one significant problem: it doesn't go backward. :lol: Which is odd. The winding is correct (clockwise -> once around pin -> counter clockwise), but when I release the lever arm it simply stops halfway. When I push the lever arm forward to simulate how the vehicle would move, it goes forward a bit more then starts moving backward, indicating the problem is perhaps in the mousetrap itself? Has anyone run into a similar issue?

Yes, this is a rule that can be questionable yet at the same time I agree why the rule is in place [if you find that the vehicle is not handling like it does at practice you obviously would change something on your vehicle to correct it] now that opportunity needs to be open to all that would like to have a practice run. That can't happen at State because there is 46ish teams there and you HAVE to provide equal treatment to all teams thus if all teams cant get a practice run the NO one can gets one. That rule is in place to prevent giving teams an unfair advantage. Their is no good way to allow equal treatment if you allowed for open runs before the event started on the tracked on which you will be judged. Case and point I would show up 1.5hr before the impounding starts and I might end up staying there until I feel the vehicle is adjusted perfectly to the floor.


But, this is perfectly allowed: because you can’t run on the track you can have some test runs in areas that are not taped off. What happens is there is always a huge line to impound so to pass time some teams made a few test runs to see how the vehicle was doing. Not perfect but that may make you a little happier.

Haha that's what I did. I meant that you test it in random places, not on the actual track...

At regionals, they hadn't even laid down the track yet.

So all 46 teams can test... There's lots of space.

So I guess I'm good :D

How there the times at your regional? I got 22second with my old vehicle how did that compare to what you saw at your regional? [Vehicle V3 = not done yet]

Does the string have tension on it for the entire run? [if there is nothing pulling on the axel that can be the cause of why your vehicle will not reverse]. I don’t exactly use your design but the principal that you use works on my vehicle well. Is the string being hocked on something? Or is our mouse trap being using all of it’s energy and your vehicle only goes halfway back? Not exactly sure what your problem may be. I’m just gave you a list of problems that I have seen happen.

that is a very good time! If you can work on your stopping distance you will have a very solid vehicle.

Also did the person that submitted the rule clarification on the track bonus ever get a reply. I'm Still waiting on mine that has sent over 3weeks ago and have yet to hear a response. Is there a limit to one question per year or something with the national clarifications I have sent 2 this year and have only got one response? I have sent more than one the last few years and have gotten a response quickly, I was just curious if they had set a limit on the clarifications one person could ask for?


They posted the answer on the National Web Page:
http://soinc.org/node/581

"The lane bonus will be given to any device whose pointer remains within the 1.5 meter lane throughout the entire run. This is consistent with the example at the end of the rules."

Thanks, I still am confused, that’s another great National Clarification, they sometime word the rules so weird. So what are they saying?

no bonus if [x = pointer of vehicle, | = 1.5 lane, _ = finish line/8m line]
__
| | X
| |
| |
| |
| |

but this one would get the - 20 bounus?

if the second pic would not get the bonus then their example is wrong!?

In your second example, the run is over when the pointer crosses the line, therefore it was still within the lane at all times during the run even if it crosses the line? In your first example, it crosses the lane boundary BEFORE the run is finished.

It should, the string is still taut when the lever arm is being pulled.

The axle was two lego rods connected with one of those blue pieces with a hole through it? I think the string keeps getting snagged on the blue piece, since when I push the lever arm, it goes forward then backward as it should....I'm planning on switching the axle, ultimately.

I agree with fleet130 that the 2nd picture should get the lane bonus......afterall, the clarification states that the example is correct......maybe that's why they put that statement there *shrug*
