Re: Testing your car on a guided track,when racing on a lane track

Think hard. Your goal is to decrease Friction. Setting up a basic rail rider, only the very bottom inside of the Dfw (dominant front wheel) ever touches the guide strip. One front wheel is raised to save "Rotational Energy". If the car is set up to run the raised wheel into the side rail you have in...

Re: Testing your car on a guided track,when racing on a lane track

MJ, I'm not following your last post. A raised wheel should never touch anything. Only the Dfw should ever touch the guide strip. Depending on what your rules allow, it might be wise to build a Hershey bar car, set the balance point 1/2" in front of the rear axle slot, and do a Super job on axles an...

Re: Testing your car on a rail track,when racing on a lane track

Up in the top right corner it says "Search". I would keep searching, using different worded questions, to see what different racers have to say. Those tracks are not very popular but if you find one expert you'll be way ahead of the game.
Best Wishes.

Re: Track material vs. track length vs. speed

Gramps, You can probably get in this years Mid America race and you're going to find out what it will do. I'm sure they have a scout class for the car and also an Adult class so it can be run somewhere following your rules. Don't change anything on the car. You can mail it in and watch the race on y...

Re: Homemade track

Lots and lots of variables. If you have a District race and they score with Elapsed time, you will then know what the fastest car ran. You'll also know what your car ran. If it turns out you have the fastest car, you're on the right track. If you give us the details of the car you are racing we migh...

Re: Degree of Wheel Cant

If rules allow the 2.5 degree cant on the rear wheels is probably the best. I suspect at 2.5 degrees the angle keeps the wheel on the nail head. Our Cub Scout rules will not allow us to do that so I'm forced to bring the cant back to 1.5 degrees where the wheel appears to be sitting closer to straig...

Re: Brand new to forum and pinewood derby

Sloroller, please allow me to share my story with you. In 1996 I was given 2 beautiful, 2 lane, professionally built wood tracks that had the guide strips with a 4" center to center. I equipped them with Microwizard timers. They served us well. A few years ago I bought a 2 lane Best track. The Best ...

Re: Design Judging Article

The Commodore Perry District is never going to get rid of the Design category and I only brought it up once. The leaders were complaining about losing so much money on the District Race I simply offered a suggestion. They weren't impressed with my suggestion and they've never complained about losing...
