Good afternoon, When weighing to find out front axle weight. As scale heights are different would you elevate the rear axle to the same height as the front axle when weighing? Thank you in advance

This is in the Performance and Conformity System instructions and should be the same for any scale: Be sure the entire weight of the car is resting on the Scale. Wheels should not touch the surface of the table. This may require setting the car on its side or on its top. You can view these instructions in their entirety on our website pinecar.woodlandscenics.com/show/item/P4035

Hi. I try to calculate the center of gravity height of the car. I raise up the front of the car to calculate the center of gravity height; and then I do again, this time I raise up the back of the car to calculate the center of gravity height, I raise up same height but I got the different answer of center of gravity height. Do you know why? Should I need to raise up the lighter side of the car to calculate the center of gravity height?

Hello Gary, Thank you for your interest in our products! If you are trying to find the center of gravity without using our app, you can do so by balancing your car on a pencil. This will tell you where the COG is. If you would like the center of gravity closer to the rear of your PineCar, you will need to move the weights back. If you would like it closer to the front, you will need to move them forward. If you have any questions you can also contact our Customer Service Department Monday through Friday from 8:00 a.m. to 5:00 p.m at 573-346-5555. CST. Thank you and happy racing!

PineCar what is optimum for not flipping??

Racers are propelled down the slope of a track by gravity, turning potential energy into kinetic energy. But, when the racer reaches the flat area of track, gravity is no longer a help. By designing a Center of Gravity (CoG) near the rear of the car, more potential energy is produced because the heaviest part of the car (mass) sets higher and has further to drop. The additional potential energy is converted into a surplus of kinetic energy, which gives the car a push to the finish line. We do recommend as a guideline your car's center of gravity be approximately 3/4" in front of the rear axle and balanced equally on both sides. For example, if the race is being held on a wood track, some believe the 1” in front of rear axle is best. If at all possible we recommend doing test runs on the track that will be used.

How do you weigh the car at the from axel?

fousies Hello! To measure the weight of your car at the front axle, you will need to place the rear wheels on a level flat surface (same height as your scale) and put your front wheels on the scale. This will give you the weight of the Front Axle. If you don’t have a scale, you might be interested in our Performance & Conformity System P4035. Here is a quick link for your convenience: pinecar.woodlandscenics.com/show/Item/P4035/page/1 Hope this helps!
