Weight-jacking for Optimum Performance
The addition of flat sheet lead weights (part TSC15) to improve or change the handling characteristics of your car is an important factor, regardless of the type of track, tires of if you use the down force-generating traction magnet or not.
First, analyze the situation to find the correct solution:
1/ The car under-steers: when attempting fast cornering, it either jumps out of the slot and wants to go straight, or stands on its side and lifts the guide out of the slot. In this case, lead weights can be added to the front and sides of the car on top of the flat areas of the steel pan, and even under the nose where the steel pan has a step on front of the guide blade. Add a little at a time until the car corners flat. There will be a limit to as much weight you can use versus a loss in acceleration and straight line performance due to...too much weight for the motor to carry. If it wants to "tilt", or stand on its side, it is also due to too much mechanical grip from the rear tires, and can be cured by using a harder tire compound or actually cutting down the width of the actual thread contacting the track surface. This can only be accomplished on a tire-cutting lathe available at specialized electric model car racing stores. Only the INNER part of the tire should be cut.
2/ The car over-steers: the car's rear wheels slide and it wants to spin when cornering. It needs more down force on its rear tires, or better rear tires for the situation. Lead weights can be applied on the flat surfaces at the rear of the steel pan, ahead of the rear wheels and even on front of the motor as needed.
3/ How to apply the weights:
-Select and cut the sheet lead pieces needed to exact size with a pair of sharp scissors.
-Press all pieces flat between two flat hard surfaces such as blocks of hard wood or aluminum.
-Apply to clean steel pan areas where needed.
