Hey what does everyone think times will be like at nats this year?

I'd say top 10 would probably be between 2-3 seconds.

What's an example of a useful sighting device for this event?

Rifle scope works. PM me for pictures if you're interested.

I know this might be a pretty stupid question but where would you place the Scope, on the actual ramp or on the vehicle when you're aiming it (If you have no guide rails)

my vehicle is experiencing major skid when it brakes. My wheels have good traction but I dont know what else I can do.

Clean the floor. Clean the wheels.

Clean the floor. Clean the wheels.

Good suggestions. Additionally: how fast are you going when you brake? What kind of brake are you using? If youre going fairly fast and have a "lock" brake (such as a wingnut), youre gonna have skid regardless of how good your brakes are and you may want to consider finding a way to have your vehicle slow down before you brake.

My current design, not built yet, has a spring on the end of the axle. The wingnut will start to slow down from the spring, but will not immediately stop the vehicle. I'm sure this is a common idea, though. Has anyone tried this?

I've been trying to find out how this works as well, but I was wondering how the car would fully come to a stop since it is never going to hit up against something to make it come to a full stop?

The wingnut will compress the spring. The spring will eventually either be all the way compressed, or it will exert a significant enough force against the wingnut, both of which will stop the vehicle. Writing this now makes me realize that, if you're not careful, the spring may be able to push your vehicle backward.
