 Frequently Asked Adhesive Questions
 

Having a balanced chassis will help your suspension do its job. To find out how much force each wheel is exerting on the track, you can use four cheap kitchen scales. Wal-Mart has them for about $4 each. You will need four of them.

Set up the scales on a flat surface, such as a table. Place your touring car on the scales so each tire is resting on a scale. ALL of your radio gear should be installed. Line up the wheels on each scale so the axle passes through the center of the scale. Before you check the weight of each wheel, make sure all the scales are level and set up correctly.
Now it's time to start reading the scales.

Record each of the measurements
Front left wheel. The scale reads ______ ounces.
Front right wheel. The scale reads ______ ounces.
Differences in the weight can largely be attributed to the fact that the batteries are located on this side of the chassis. Depending on the weight of your Servo, ESC, Motor, and Receiver, they might not be enough to balance out the weight of the cells on the opposite side of the chassis.
Rear left wheel. The scale reads ______ ounces.
Rear right wheel. The scale reads ______ounces.
Depending on how your chassis is set up, having the front and rear exerting different amounts of force isn't always a bad thing. Having more weight in the back of the car will give the rear wheels more traction.
Now knowing how much force each wheel is exerting on the track, the right and left sides can be equaled out. The first way is equalize sides is to use lead weight to balance out the chassis. The next is to arrange the electronics, so the weight equals out the sides. Use a fake transponder to simulate what the car will be like during actual racing conditions. Remember, the ROAR limit for minimum weight is 53 ounces (Don't forget the weight of the body and don't included the transponder). If you go over this limit when you add lead weight, try to bring your chassis's weight down by replacing heavier parts with lighter parts. Good examples of these types of parts are steel turnbuckles (replace them with titanium), steel CVDs (replace them with plastic or aluminum), or chassis (replace it with a graphite or milled version). The last way to compensate for more weight on one side of the chassis is to add more "Pre-Load" to the shock. Pre-Load is the force the spring is exerting down on the shock. You can compensate for the extra weight by compressing the spring on the shock. This will help to balance out the forces. This is sort of a trial and error method, since it's hard to measure the extra force the pre-load is compensating for.
