  • Chassis tuning with added weight

    This was just a simple test to see if adding weight, and where it is placed had much of an effect on slot car handling on the skid pad.

    The skid pad is just a place to start tuning the chassis and will only give the performance of a car in a continuous turn.

    The final amount and where the weight is placed is determined by the carís total performance on the race track.

    This test was performed with a brass test chassis of the same dimensions as a Slot it Porsche 956 with the motor mounted sidewinder.

    The brass test chassis weighed 65 grams with 41 grams on the rear tires.
    Fastest continuous speed.
    0.780 seconds

    A 9 gram weight was added to the front to give the chassis a weight of 74 grams, 43 grams on the rear, which is equal to a Slot it 956.
    Fastest continuous speed.
    0.730 seconds

    The 9 gram weight was moved to the center of the chassis, placing 46 grams on the rear wheels.
    Fastest continuous speed.
    0.810 seconds

    The 9 gram weight was moved to the rear and placed against the front of the motor, placing 48 grams on the rear wheels.
    Fastest continuous speed.
    0.840 seconds

    The 9 gram weight was moved to the back and attached behind the motor, placing 52 grams on the rear tires.
    Fastest continuous speed.
    0.800 seconds

    All the tests were done using Slot it S1 tires on my polished Sears Semi-Gloss Latex Painted MDF track.
