oops meant :)
There are many ways to do it. Read the wiki. Lots of useful info. to those getting started.

can you turn in the pages when you go to test your vehicle?
Read the rules. It's 4 pages at impound.
Hopefully the vehicle part is just a careless mistake...
Electric Vehicle C or Scrambler B are the build events that involve vehicles. Air Trajectory B/C involves launching a projectile by air pressure.

Would they let you switch out air chambers between launches if you included the other chambers at impound? This obviously isn't the best way to design the device but in the rules it says that you can recalibrate the device but I'm not sure if they would let you change out parts.

I see no reason why not

Are there any changes to the scoring system?
Are there basic design that someone could suggest?

I don't think there are any changes to the scoring system. I did a air chamber.

The bucket shots are now worth 300 points. Instead of 100 for hitting the side and 100 for getting it inside the bucket, it's now 200 for getting it inside the bucket.

Im still confused on the concept of the left and right of the centerline. So if it was a xy coordinate plane, the x-coordinates of the targets could only be -2, 0, and 2? Or can it be any other x-coordinate in between -2 and 2. Thanks in advance!

By rule 4.e., the far target can be up to 2.00 m to the right or left of the imaginary centerline, in intervals of 0.5 m for Regionals, 0.25 m for States, and 0.10 m for Nationals. So for State, your x-coordinate can only be: -2.00, -1.75, -1.50, -1.25, -1.00, -0.75, -0.50, -0.25, -0.00, 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, where the centerline is located at x = 0. The near target must be centered (i.e. its x-coordinate can only be 0).

Do you think a trebuchet would be too strong for Air Trajectory? I am in Division B.

Also, is the graph template for Division B available yet? On the event sheet it says that it is available on the website, but it says that it is not available yet.

What is the max degree for div B that the target can be placed away to the right or left from the center?

The far target is the only one that does not need to be on the centerline, and it can be placed up to 2.00 m left or right of the centerline, and between 2.00 and 8.00 meters in the launch direction. The largest angle you would turn your device happens when the target is 2.00 m away in the launch direction and 2.00 m left or right of the centerline. This angle is arctan(2.00/2.00) = 45 degrees. This assumes your device launches the projectile perfectly straight towards the launch direction.

Do you believe a trebuchet would be able to shoot perfectly straight? I am worried about it launching with too much velocity and that it will go too high and go over the target.

Also, will I be allowed to pull a string to release the hook and activate the trebuchet?
