The distance is measured in centimeters, so there is a larger emphasis on speed than last year.

### Re: Mousetrap Vehicle B

I know this really doesn't relate to the current topic, but should I use a braking system? If so, what kind of breaking system (name) and how would I install it on a piece of balsa? I'm already considering the "Wingnut" system but I was just wondering if anyone else had any other methods.

You could use the string that is pulling the back or front axle and wind it the opposite way once around. Hope this helps!

### Re: Mousetrap Vehicle B

This is what the rules has for an example of a run score:

Distance Off Score 155.3 cm
Time Score +28.95 (which is 5.79 seconds x 5)
Total Run Score =184.25

Is the distance off actually being scored as centimeters??? This would weight the time score extremely. For example, Team A gets only 1 cm off from the target point, while team B is 10 cm off. Team A's run took 8 seconds, and team B's took 6, a difference of only 2 seconds. This would mean that team A gets 41 points and B gets 40, meaning B would win. Even though Team A was a mere 1 cm off compared to ten, a run time margin of 2 seconds put B over the top, which doesn't make sense to me.
Is this a mistake in the rules? Is the distance off score actually based off the number of millimeters away from the target point?
The score is measured in millimeters. Five centimeters off equals 50 points, or 10 seconds. Accuracy matters very much, trust me.
A Person, where did you hear that the score would be in mm?

### Re: Mousetrap Vehicle B

NC rule states, "Competitors must start the vehicle by actuating a trigger using an unsharpened #2 pencil, with an unused erased. The trigger must be designed so that its actuation is perpendicular (vertical) to the floor. A non-vertically activated trigger will be considered a construction violation."
Then a clarification came up on the NC website that states, "NC Only - RULE 3.h. has been changed to: Competitors must start the vehicle by actuating a trigger using an unsharpened #2 pencil, with an unused eraser (supplied by the Event Supervisor). The trigger must be designed so that its actuation is perpendicular (vertical) to the floor. A non-vertically activated trigger is a construction violation. The pencil cannot be the actuation switch/trigger. (1/14/13)" (See the last sentence).
Since the pencil cannot be the activation trigger, I was wondering if anybody had any suggestions.

### Re: Mousetrap Vehicle B

Yesterday, at invitationals, I got top 10 in 3 events, but mousetrap vehicle was the only one where I placed (6th). This isn't a good thing, because the only people who worked on it were my partner & his family. I virtually did nothing. I knew how the vehicle worked, and I was busy with other events (rotor egg drop, write it do it, rocks). Who thinks that I should be proud of my ribbon?

Can the extension bar be part of a Fishing rod? Can it be flexible or not?
